Moringa oleifera native to India, grows in the tropical and subtropical regions of the world. It is commonly known as ‘drumstick tree’ or ‘horse radish tree’. With its high nutritive values, every part of the tree is suitable for either nutritional or commercial purposes. The leaves are rich in minerals, vitamins and other essential phytochemicals. Extracts from the leaves are used to treat malnutrition, augment breast milk in lactating mothers It is used as potential antioxidant, anticancer, anti-inflammatory, antidiabetic and antimicrobial agent. The scientific effort of this research provides insights on the use of moringa as a cure for diabetes and cancer and fortification of moringa in commercial products. Moringa oleifera have been evaluated for its antioxidant activity. M. oleifera leaves were extracted with methanol, ethyl acetate, dichloromethane and n-hexane. The antioxidant activity of extracts were evaluated by 1,1 diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging activity assay, Ferric reducing antioxidant power, Hydrogen peroxide scavenging assay, Metal chelating Agents. Trolox was used as standard for M. oleifera leaves possess antioxidant.
The leaves of M. oleifera are rich in minerals like calcium, potassium, zinc, magnesium, iron and copper. Vitamins like beta-carotene of vitamin A, vitamin B such as folic acid, pyridoxine and nicotinic acid, vitamin C, D and E also present in M. oleifera. Phytochemicals such as tannins, sterols, terpenoids, flavonoids, saponins, anthraquinones, alkaloids and reducing sugar present along with anti-cancerous agents like glucosinolates, isothiocyanates, glycoside compounds and glycerol-1-9- octadecanoate. Cancer is a common disease and one in seven deaths is attributed due to improper medication. Around 2.4 million cases are prevalent in India, while there are no specific reasons for cancer to develop. Several factors like smoking, lack of exercise and radiation exposure can lead to the disease. Cancer treatments like surgery, chemotherapy and radiation are expensive and have side effects. M. oleifera can be used as an anticancer agent as it is natural, reliable and safe, at established concentrations. Studies have shown that moringa can be used as an anti-neoproliferative agent, thereby inhibiting the growth of cancer cells. Soluble and solvent extracts of leaves have been proven effective as anticancer agents. Furthermore, research papers suggest that the anti-proliferative effect of cancer may be due to its ability to induce reactive oxygen species in the cancer cells. Researchs show that the reactive oxygen species induced in the cells leads to apoptosis. This is further proved by the up regulation of caspase 3 and caspase 9, which are part of the apoptotic pathway. Moreover, the ROS production by moringa is specific and targets only cancer cells, making it an ideal anticancer agent. Tiloke et al. also showed that the extracts increased the expression of glutathione-S-transferase, which inhibits the express of antioxidants. Anticancer agents targeting cancer using ROS induction are common, but these substances should also be able to attack the antioxidant enzymes. However, Moringa leaf extracts have been shown to be antioxidants and anticancer agents which induce ROS. The exact behavior of the two contrary attributes of the leaves is yet to be explored. The compounds of the leaves that are held responsible for the anticancer activities are glucosinolates, niazimicin and benzyl isothiocyanate. Benzyl isothiocyanate has been shown to be linked with cancer. Free radical and reactive oxygen species are well known as inducers of cellular and tissue pathogenesis which is causing some diseases like diabetes, cancer, inflammatory and also cardiovascular. Free radical reactions take place in the human body and food systems can causing injury and death [1].
Free radicals are one of the main factors which necessary to cause DNA mutation, which is involve in the initiation stage of carcinogenesis [2]. Reactive Oxygen Species (ROS) are constantly produced in human body by normal metabolic system. An over-production of reactive oxygen can occur the imbalance of defense system. Therefore, investigations of antioxidants are needed which focused on natural compounds from natural sources. The most widely used synthetic antioxidants in food are butylated hydroxytoluene (BHT) or butylated hydroxyanisole (BHA). Both of them are very effective as antioxidants but their use in food products is not popular anymore due to their instability and also due to a suspected action as promoters of carcinogenesis. For this reason, there is another interest in the studies of natural healthy (non-toxic) additives as potential antioxidants [3]. The total antioxidant capacity values should include methods applicable to both lipophilic and hydrophilic antioxidants, with regards to similarity and differences of both hydrogen atom transfer and electron transfer mechanism [4]. Some methods have been used to evaluate antioxidant activities of natural compounds by using stable free radical DPPH. Ferric Reducing Antioxidant Power (FRAP), indicating strong, concentration-dependent antioxidant capacity. Hydrogen peroxide scavenging assays in Moringa oleifera leaves demonstrate significant antioxidant potential, often measured by the decrease in absorbance of hydrogen peroxide at 230 nm. Methanolic or ethanolic extracts show high scavenging activity, with reports indicating up to 82% efficacy, often comparable to standards like BHT or ascorbic acid. Metal chelating agent against heavy metals (As, Cd, Ni, Pb, Cu) due to its rich content of phytochemicals specifically polyphenols like gallic acid, flavonoids, tannins, and phytates. These compounds, along with functional groups on the plant’s surface. Most of the antioxidant compounds derived from plant source have wide variety and chemical properties. The antioxidant characteristic is based on its ability to trap free radicals. Moringa oleifera (Moringaceae; Indonesian name: kelor) is an ornamental plant native in tropical and subtropical areas, and commonly cultivated in all region of Indonesia as a vegetable for cooking purposes. All parts of this plant had been reported to have variously biological activities such as reducing hyperglycemia [6] anti-inflammatory, anti-diabetic, antimicrobial, anticancer and antioxidant [7]. Kelor Leaves extracts were also found have antioxidant activities with linoleic acid, α-tocopherol and sunflower oil [8]. In Asia and Africa, the leaves is recommended as a supplement because of rich in nutrients for breastfeeding mothers and infant [9]. Nitrile compounds, mustard oil glycosides, benzyl glycosides, phenolic glycosides, flavonoid glycosides, thiocarbamate glycosides and amino acids had been isolated from this plant [7]. The antioxidant activities extract MeOH of M. oleifera leaves showed the IC50 = 1.60 ± 0.03 mg/mL in DPPH assay [10]. M. oleifera leaves contain of natural source of polyphenol that potential to have antioxidant. The purpose of this paper is to evaluate the antioxidant activity of various extract of M. oleifera leaves.
1. PROPERTIES OF MORINGA OLEIFERA
Moringa is rich in nutrition owing to the presence of a variety of essential phytochemicals present in its leaves, pods and seeds. In fact, moringa is said to provide 7 times more vitamin C than oranges, 10 times more vitamin A than carrots, 17 times more calcium than milk, 9 times more protein than yoghurt, 15 times more potassium than bananas and 25 times more iron
than spinach [11]. Children deprived of breast milk tend to show symptoms of malnutrition. Lactogogues are generally prescribed to lactating mothers to augment milk production. The lactogogue, made of phytosterols, acts as a precursor for hormones required for reproductive growth. Moringa is rich in phytosterols like stigmasterol, sitosterol and kampesterol which are precursors for hormones. These compounds increase the estrogen production, which in turn stimulates the proliferation of the mammary gland ducts to produce milk. It is used to treat malnutrition in children younger than 3 years [3]. About 6 spoonfuls of leaf powder can meet a woman's daily iron and calcium requirements, during pregnancy. This study provides an overview on the cultivation, nutritional values, medicinal properties for commercial use and pharmacological properties of moringa. There are no elaborate reports on treatment of diabetes and cancer using moringa.
2. NUTRITIVE PROPERTIES
Every part of M. oleifera is a storehouse of important nutrients and antinutrients. The leaves of M. oleifera are rich in minerals like calcium, potassium, zinc, magnesium, iron and copper. Vitamins like beta-carotene of vitamin A, vitamin B such as folic acid, pyridoxine and nicotinic acid, vitamin C, D and E also present in M. oleifera [12]. Phytochemicals such as tannins, sterols, terpenoids, flavonoids, saponins, anthraquinones, alkaloids and reducing sugar present along with anti-cancerous agents like glucosinolates, isothiocyanates, glycoside compounds and glycerol-1-9-octadecanoate [13]. Moringa leaves also have a low calorific value and can be used in the diet of the obese. The pods are fibrous and are valuable to treat digestive problems and thwart colon cancer [14]. Aresearch shows that immature pods contain around 46.78% fiber and around 20.66% protein content. Pods have 30% of amino acid content, the leaves have 44% and flowers have 31%. The immature pods and flowers showed similar amounts of palmitic, linolenic, linoleic and oleic acids [15]. Moringa has lot of minerals that are essential for growth and development among which, calcium is considered as one of the important minerals for human growth. While 8 ounces of milk can provide 300–400 mg, moringa leaves can provide 1000 mg and moringa powder can provide more than 4000 mg. Moringa powder can be used as a substitute for iron tablets, hence as a treatment for anemia. Beef has only 2 mg of iron while moringa leaf powder has 28 mg of iron. It has been reported that moringa contains more iron than spinach [16]. A good dietary intake of zinc is essential for proper growth of sperm cells and is also necessary for the synthesis of DNA and RNA. M. oleifera leaves show around 25.5–31.03 mg of zinc/kg, which is the daily requirement of zinc in the diet [17]. PUFAs are linoleic acid, linolenic acid and oleic acid; these PUFAs have the ability to control cholesterol. Research show that moringa seed oil contains around 76% PUFA, making it ideal for use as a substitute for olive oil [18]. A point to note is that the nutrient composition varies depending on the location. Fuglie revealed that seasons influence the nutrient content. It was shown that vitamin A was found abundantly in the hot wet season, while vitamin C and iron were more in the cool-dry season [19]. The difference in results can be attributed to the fact that the location, climate and the environmental factors significantly influence nutrient content of the tree.
3. MEDICINAL PROPERTIES
M. oleifera is often referred as a panacea and can be used to cure more than 300 diseases. Moringa has long been used in herbal medicine by Indians and Africans. The presence of phytochemicals makes it a good medicinal agent. In this section the effect of moringa on diseases like diabetes and cancer are reviewed.
Anti-diabetic properties:
Diabetes leads to several complications such as retinopathy, nephropathy and atherosclerosis etc. Moringa can be used to prevent such ailments. When there is hyperglycemia, the blood glucose reacts with proteins and causes advanced glycated end products (AGEs). These AGEs bind to RAGE which gets expressed on the surface of immune cells. This interaction leads to increased transcription of cytokines like interleukin-6 and interferons. At the same time, the cell adhesion molecules are expressed on the surface endothelium of arteries [20]. Moringa is used as an anti-atherosclerotic agent [21]. An anti-atherogenic nature can be accounted for by the antioxidant properties of moringa.
4. ANTICANCER PROPERTIES
Cancer is a common disease and one in seven deaths is attributed due to improper medication. Around 2.4 million cases are prevalent in India, while there are no specific reasons for cancer to develop. Several factors like smoking, lack of exercise and radiation exposure can lead to the disease [22]. Cancer treatments like surgery, chemotherapy and radiation are expensive and have side effects. M. oleifera can be used as an anticancer agent as it is natural, reliable and safe, at established concentrations. Studies have shown that moringa can be used as an anti-neoproliferative agent, thereby inhibiting the growth of cancer cells. Soluble and solvent extracts of leaves have been proven effective as anticancer agents. Anticancer agents targeting cancer using ROS induction are common, but these substances should also be able to attack the antioxidant enzymes [23]. However, Moringa leaf extracts have been shown to be antioxidants and anticancer agents which induce ROS. The exact behavior of the two contrary attributes of the leaves is yet to be explored. The compounds of the leaves that are held responsible for the anticancer activities are glucosinolates, niazimicin and benzyl isothiocyanate [24]. Benzyl isothiocyanate has been shown to be linked with cancer. Research shows that BITC causes intracellular ROS, which leads to cell death. This could be one of the reasons for moringa to be a good anticancer agent [25,26].
5. COMMERCIAL APPLICATIONS
Moringa seeds are used to extract oil called the Ben oil. This oil is rich in oleic acid, tocopherols and sterols. It can also withstand oxidative rancidity. The oil can be used in cooking as a substitute for olive oil, as perfumes and also for lubrication [27,28]. The pods can absorb organic pollutants and pesticides. Moringa seeds also have great coagulant properties and can precipitate organics and mineral particulates out of a solution [29,30]. Chemical coagulants such as aluminum sulfate (Alum) and ferric sulfate or polymers removes suspended particles in waste water by neutralizing the electrical charges of particles in the water to form flocs making particles filterable. M. oleifera seed is a natural coagulant, containing a cationic protein that can clarify turbid water. This property of M. oleifera seeds is attracting much research as other coagulants such as alum, activated carbon and ferric chloride are expensive and rare [31]. They developed a two stage clarifier for the treatment of tapioca starch waste water by placing coconut fiber followed by a layer of sand media mixed with powdered M. oleifera, this lead to improvement on physical and chemical characteristics, stabilizing pH value. Moringa seed extract has the ability to eliminate heavy metals (such as lead, copper, cadmium, chromium and arsenic) from water [33]. M. oleifera functionalized with magnetic nanoparticles such as iron oxide were found beneficial in surface water treatment by lowering settling time [34]. Seed extracts have antimicrobial properties that inhibit bacterial growth, which implies preventing waterborne diseases. These properties of M. oleifera seeds have wide applicability in averting diseases and can enhance the quality of life in rural communities as it is highly abundant.

Antioxidant assay
DPPH radical scavenging assay
The radical scavenging activity of M. oleifera extracts against the DPPH radical was determined by the method of Brand Williams with slightly modified by Dudon?e et al. [11,12]. Determination procedures were as follow: 1 mL of 6 × 10−5 M DPPH radical solution (prepared daily) was mixed with 33.33 μL of methanolic solutions of M. oleifera extracts (maximum dissolved concentration). After 20 min incubation for at 37 °C, absorbance decrease of the mixture was monitored at 515 nm (As). During reduction by the antioxidant, the solution colour changed from violet to yellow pale. DPPH radicals have an absorption maximum at 515 nm. Blank samples with 33.33 μL of methanol in the above DPPH radical solution were prepared and measured daily at same wavelength (Ab). Trolox was used as positive control. The experiment was carried out in triplicate.
Radical scavenging activity was calculated using the following formula.
Inhibition rate (%) =[Ab-As/Ab] ×100
Ab=Absorbance of control
As=Absorbance of sample
The 50% inhibitory concentration (IC50) was expressed as the quantity of the extracts to react with a half of DPPH radicals.
Ferric Reducing Antioxidant Power (FRAP) Assay
Moringa (Moringa oleifera) leaves possess exceptionally high Ferric Reducing Antioxidant Power (FRAP), indicating strong, concentration-dependent antioxidant capacity (approx. 0.49–3.96 mmol/g or 3.05–1752 mg/g depending on drying method and solvent). Air-dried, sun-dried, and protein extracts show superior antioxidant capacity compared to fresh leaves, with values often exceeding those of common vegetables [31].
Key Findings on Moringa FRAP
High Antioxidant Capacity: Moringa leaves have one of the highest FRAP values compared to other leafy vegetables, showcasing strong reduction of Fe (III) to Fe (II).
Processing Effects: Air-dried leaves exhibit higher reducing power than fresh or oven-dried forms.
Extraction Method: Protein extracts and ethanolic/methanolic extracts show significant, sometimes higher, FRAP values compared to aqueous extracts, driven by polyphenols, flavonoids, and Vitamin C.
Measurement Range: Studies indicate varying results based on methodology, such as 0.49–0.7 mmol/g and 0.41–2.68 mg/g.
Factors Influencing Activity: The antioxidant potential depends on drying temperature, soil, season, and geographical location, with some studies reporting 3.05±0.15 mgTE/g.
Biomedres
FRAP, which operates by reducing Fe (III)-2,4,6-tripyridyl-s-triazine (TPTZ) to the intense blue Fe (II)-TPTZ complex at pH 3.6, confirms that Moringa leaves are a rich source of dietary antioxidants.
Hydrogen Peroxide scavenging Assay
Hydrogen peroxide scavenging assays in Moringa oleifera leaves demonstrate significant antioxidant potential, often measured by the decrease in absorbance of hydrogen peroxide at 230 nm. Methanolic or ethanolic extracts show high scavenging activity, with reports indicating up to 82% efficacy, often comparable to standards like BHT or ascorbic acid. [32]
Key Aspects of the Assay in Moringa Leaves
Principle: The assay measures the ability of antioxidants (phenolics/flavonoids in Moringa) to reduce H2O2 to water.
Procedure: Typically, hydrogen peroxide (40 mM) is prepared in phosphate buffer (pH=7.4). Different concentrations of Moringa extract are added, incubated (e.g., 10 min), and absorbance is measured at 230 nm.
% scavenged (H2O2) = [(Ai – At)/Ai] ×100
where Ai is the absorbance of control and At is the absorbance of test.
Results: Moringa oleifera extracts showed values for hydrogen peroxide scavenging between 280 and 340 which indicates substantial, though lower, activity compared to standard ascorbic acid.
Optimal Conditions: Studies have shown maximum scavenging activity in methanolic extracts of Moringa stenopetala at 10-minute intervals, with notable activity at concentrations around 60g/mL.
Biological Significance: The high scavenging capacity of Moringa leaves protects cells from hydrogen peroxide-induced oxidative damage and increases cell viability, as seen in MTT assays on KB cells.
Metals Chelating Agent
Moringa oleifera acts as a natural chelating agent against heavy metals (As, Cd, Ni, Pb, Cu) due to its rich content of phytochemicals—specifically polyphenols like gallic acid, flavonoids, tannins, and phytates. These compounds, along with functional groups on the plant’s surface (carboxyl, hydroxyl), bind metal ions to reduce toxicity, reduce ROS accumulation, and assist in biosorption, particularly using seed and leaf extracts. [33]
Key Metal Chelating Components and Mechanisms
Gallic Acid: Identified as a crucial component in leaf extracts, using its hydroxyl and carboxyl groups to chelate toxic metals such as Arsenic (As (III)).
Polyphenols & Flavonoids: These antioxidants in Moringa reduce heavy metal-induced oxidative stress and bind metal ions to facilitate their removal.
Proteins (Seeds): Moringa seed biomass possesses high binding affinity for metals like (Pb (II)), (Cu (II)) and (Cd (II)) acting as an effective biosorbent.
Functional Groups: The surface morphology of Moringa tissues contains carboxylic, phenolic, and amine groups that act as ligands for metal ions.
CONCLUSION
Antioxidant activies of M. oleifera extracts with various solvents (methanol, ethyl acetate, dichloromethane, and n-hexane) were determined using DPPH. MeOH extracts showed the highest antioxidant activity DPPH free radical scavenging. This finding provides scientific evidence for the Indonesian traditional people way, which used M. oleifera leaves as one of nutrition food to prevent diseases. This study also indicated that M. oleifera leaves can be used as antioxidant source.
