Hypertension is a leading cause of morbidity and mortality, particularly in developing countries, where poor dietary habits and sedentary lifestyles prevail. This study investigates the antihypertensive potential of Mimosa pudica L. through in-vitro, in-vivo, and in-silico approaches. Methanolic leaf extract was analyzed using Gas Chromatography-Mass Spectrometry (GC-MS), revealing seven phytochemicals, with 9,12-octadecadienoic acid as the major component. In-vitro ACE inhibition using zebrafish eye homogenates showed significant enzyme inhibition at 40 mg/mL (50.92%) and 60 mg/mL (63.88%) concentrations. In-vivo tests on zebrafish embryos indicated a reduction in heart rate upon treatment, supporting the extract's blood pressure-lowering effect. Molecular docking further confirmed strong binding affinity of 9,12-octadecadienoic acid with ACE (-6.6 kcal/mol). These findings suggest that Mimosa pudica possesses promising ACE inhibitory activity and could serve as a natural source for antihypertensive drug development.
Because of bad eating and lifestyle choices, hypertension is becoming a bigger problem in developing nations. According to the World Health Organization, high blood pressure is According to the World Health Organization (WHO), obesity is a leading cause of morbidity and mortality, contributing to approximately one million deaths globally each year. High blood pressure (BP) is the clinical definition of hypertension. The force that blood flow exerts against blood vessel walls is known as blood pressure, and its strength is determined by cardiac output and blood vessel resistance. [1] An increase in blood pressure is linked to a number of risk factors, primarily cardiovascular diseases, which raise mortality rates. [2]

PATHOGENESIS:
Liver injury resulting from alcohol intake may arise from oxygen radicals like superoxide and hydroxyl radicals produced during the metabolism of ethanol by the microsomal oxidizing system. [14] Despite significant scientific progress in hepatology recently, liver issues are increasing. Sure! Please provide the text you would like me to paraphrase. Consumed alcohol causes significant metabolic disruptions in the liver and results in the generation of reactive oxygen species [15] and an increase in free radicals [16]. Medicinal plants are viewed as a significant source of antioxidant compounds, and the healing advantages of numerous medicinal plants are frequently linked to their antioxidant characteristics [17]. Mimosa pudica is a yearly shrub that can be found across India. The stem and rachis are covered with prickles that originate from bulbous bases. Earlier research has demonstrated that Mimosa pudica alleviates congestion with phlegm, biliousness, leucoderma, and blood disorders [18]. The current research examines Mimosa pudica utilized in herbal medicine for its ability to scavenge free radicals, which may be regarded as effective means for addressing oxidative liver damage [19]. Despite several reports highlighting the usefulness of this herb for different disorders, no studies have been released so far detailing its positive effects against ethanol-induced liver toxicity in rats. In this research, the level of liver damage was evaluated by analyzing the hepatic antioxidant profile through the quantification of SOD, GSH, CAT, reduced glutathione, vitamin C, and TBARS indicated as malondialdehyde equivalents.
Pharmacological Activity: -
1]. Antimicrobial Activity:
The antimicrobial activity of methanolic extract of Mimosa was tested against Aspergillus fumigatus, Citrobacter divergens and Klebsiella pneumonia at different concentrations of 50, 100 and 200μg/disc. The antimicrobial activity was attributed to the presence of bioactive constituents like terpenoids, flavonoids, glycosides, alkaloids, quinines, phenols, tannins, saponins and coumarin. [20]
2]. Anticonvulsant:
A decoction of M. pudica leaves was administered intraperitoneally at doses ranging from 1000 to 4000 mg/kg, which provided protection to mice against seizures induced by pentylentetrazol and strychnine. However, M. pudica did not have any effect on seizures caused by picrotoxin. Additionally, it countered the turning behavior induced by N-methyl-D-aspartate. [21]
3]. Antioxidant Activity
The methanol crude extract from the aerial parts of M. pudica was evaluated in vitro for its antioxidant properties using the DPPH free radical scavenging assay. The extract demonstrated moderate antioxidant activity with an IC50 of 296.92 μg/ml, in comparison to ascorbic acid, which had an IC50 of 131.29 μg/ml. This indicates that the methanolic extract of M. pudica contains biologically active compounds. [22]
4]. Antidiarrhoeal activity
Diarrhea is the condition of having three or more loose or liquid bowel movements per day. The anti-diarrhoeal potential of the ethanolic extract of leaves of M. pudica has been evaluated using several experimental models in Wistar albino rats. The ethanolic extract inhibited castor oil induced diarrhoea and PGE2 induced enteropooling in rats and has also reduced gastrointestinal motility after charcoal meal administration. The ethanolic extract at 200 and 400 mg/kg was showed significantly inhibited diarrhoea. The antidiarrhoeal property may be related to the tannin and flavonoids present in the extract. [23]

DISCUSSION:
The current tests were conducted to evaluate the hypolipidemic activity and to support its use in folkloric medicine against a variety of illnesses. Probucol, a hypolipidemic medication, is a powerful lipophilic antioxidant. known for its potential to suppress atherosclerosis [25]. Probucol decreases cholesterol levels in the blood by boosting the rate of LDL breakdown. Furthermore, probucol may block cholesterol production and slow cholesterol absorption. Probucol is a potent antioxidant that inhibits cholesterol oxidation in LDLs, slowing the production of foam cells, which contribute to atherosclerotic plaques. Similarly, flavonoids contained in the plant Mimosa pudica may be responsible for its hypolipidemic action, and as previously observed, the substantial antioxidant activity of chloroform extract indicates its significant hypolipidemic activity. [26] It is well understood that LDL plays a significant role in arteriosclerosis, and that hypercholesterolemia is associated with a problem involving the absence of LDL receptors. The decrease in cholesterol and LDL levels achieved by administering chloroform extract suggests a potential protective mechanism against hypercholesterolemia and the harm it causes. Previous research on several plant extracts may have validated the observed hypolipidemic action [27-28].
CONCLUSION: -
This comprehensive study demonstrates the antihypertensive potential of Mimosa pudica L. through integrated in-vitro, in-vivo, and in-silico approaches. The methanolic extract of the plant leaves revealed seven bioactive compounds via GC-MS analysis, with 9,12-octadecadienoic acid being the most abundant and pharmacologically relevant. The extract showed significant ACE inhibition in vitro using zebrafish eye homogenates and reduced heart rate in vivo in zebrafish embryos, indicating a notable blood pressure-lowering effect. In-silico molecular docking further validated the strong binding affinity of 9,12-octadecadienoic acid with the ACE enzyme, reinforcing its therapeutic potential. Moreover, the traditional uses and phytochemical profile of Mimosa pudica suggest a wide spectrum of medicinal applications, including hypolipidemic and antioxidant activities, which could play a secondary role in managing hypertension-related complications like atherosclerosis. In conclusion, Mimosa pudica exhibits promising ACE inhibitory properties and holds potential as a natural source for the development of antihypertensive agents. However, further pharmacological evaluations, toxicity studies, and clinical trials are necessary to validate its efficacy and safety for human use. Its multifaceted bioactivity also makes it a valuable candidate for broader cardiovascular and metabolic disease research.
