Abstract

A simple, accurate, precise, and economical Q-absorbance ratio UV-spectrophotometric method was developed and validated for simultaneous estimating Rosuvastatin Calcium and Ezetimibe in combined tablet dosage form. The solvent used was a 1:1 t mixture of Isopropyl alcohol and distilled water. Two wavelengths 244nm (?max of Rosuvastatin Calcium) and 240nm (Isoabsorptive point) were selected to estimate Rosuvastatin Calcium and Ezetimibe for the Q-Absorbance ratio method. The drug concentration was determined using the ratio of absorbance at the iso-absorptive point (?1 = 240 nm) and the ?max of Rosuvastatin Calcium (?2 = 244 nm). This method is linear for both drugs in the range of 5 to 25 ?g/ml at ?1 (R2 = 0.998) and at ?2 (R2 = 0.997) for Rosuvastatin Calcium, and Ezetimibe in the range of 5 to 25 ?g/ml for found at ?1 (R2 = 0.9992) and ?2 (R2 = 0.9993). The percentage recovery was 102.11 % of Rosuvastatin Calcium and 99.72 % of Ezetimibe by standard addition method. The LOD was found to be 1.126 ?g/ml and 1.400 ?g/ml for Rosuvastatin Calcium at ?1 and ?2 respectively. The LOD was found to be 0.713 ?g/ml and 0.396 ?g/ml for Ezetimibe at ?1 and ?2 respectively. The LOQ was found to be 3.412?g/ml and 4.240?g/ml for Rosuvastatin Calcium at ?1 and ?2 respectively. The LOQ was found to be 2.162?g/ml and 1.199?g/ml for Ezetimibe at ?1 and ?2 respectively. The method was precise as % RSD was found to be less than 2 in Repeatability and Interday for Rosuvastatin Calcium and Ezetimibe. The % assay of analyte drugs in the combined tablet dosage form was found to be 101.41% of Rosuvastatin Calcium and 99.24 % of Ezetimibe which showed good applicability of the developed method.

Introduction

Worldwide under health sciences and for therapeutic protocol, ancient and historical literature reported huge knowledge of diseases and medication related    to information provided ayurveda and folk theories [1]. According to Botanical Survey of India, near about 46,000 species of plant were identified and reported , where more than 7,000 plants species were  documented for variety of medicinal features [2]. Among these plants, Ocimum sanctum (OS) commonly known as  Tulsi found as sacred plant according to  Hindu religion all over India . OS most respectful herb in all over the world [3].

In the phytoremedial procedure about all the part like leaves, stem, flower, root, seeds or  even whole plant of OS prominently  used for various  treatments like bronchitis, malaria, diarrhoea, dysentery, skin disease, arthritis, eye diseases, insect bites, anti-fertility, anticancer, antifungal, antimicrobial, cardioprotective, analgesic, antispasmodic and adaptogenic actions. Biochemicaly alcoholic extract of OS reported for  numerous pharmacological activities like hypoglycaemic, immunomodulatory, antistress, analgesic, antipyretic, anti-inflammatory, anti-ulcerogenic, antihypertensive, CNS depressant, radioprotective, antitumour and antibacterial activity [4, 5]. Genus Ocimum belonging to family Labiatae with variety of species with different therapeutic uses including Ocimum sanctum L. (Tulsi), Ocimum gratissium (Ram Tulsi), Ocimum canum (Dulal Tulsi), Ocimum basilicum (Ban Tulsi), Ocimum kilimandscharicum, Ocimum ammericanum, Ocimum camphora, Ocimum minimum L., Ocimum tenuiflorum L. and Ocimum micranthum etc.[6]. Since ancient period, among phytoremedial herb, genus Amaranth has notably reported for to treat conditions like diuretic, useful  in cold and cough, urinary and throat troubles and  gastric problems. Seed of amaranth were used in hypertension, cardiovascular disease, reducing blood pressure, lowering cholesterol, also it is used in piles, blood purify and antiscorbutic [7]. Specially Amaranthus viridis (AV) among the group  has anti-inflammatory feature used in  vermifuse, diuretics and also  for the treatment of  kidney stones as antiurolithiatic agent [8]. In traditional Indian medicines, Cystone is a polyherbal ayurvedic formula known for treatment of, burning micturition , urinary tract complications in pregnancy and other various renal disorders [9]. Each tablet form contains approximately  130 mg  Didymocarpus pedicellate, 98 mg Saxifraga ligulate, 32 mg Rubia cordifolia, Cyperus scariosus , 32 mg Achyranthes aspera, 32 mg Onosma bracteatum , 32 mg Vernonia cinerea, 26 mg Purified Shilajeet  and 32 mg Hajrul yahood Bhasma [10]. By taking account of available phytomedicinal literature and pathological scenario present investigation was focused to find out comparative efficiency and   biochemical screening of main  bioactive compounds from two different plant species, pertaining to understand and upgrade traditional knowledge for its better application against some urolithiatic condition.

MATERIALS AND METHODS :

Plant Sample:

The best quality and non infected  seeds of Ocimum sanctum and Amaranthus viridis was collected from the local market from Kolhapur, Maharashtra, India. The tablet Cystone (Himalaya, Batch No.106221154  ) was procured from local pharmacy.

DISCUSSION :

By the therapeutic point of view generally  phytochemicals were reported as biologically active compounds, which protect animals from natural or induced toxic chemicals, pathogen where disease causing microbes are in association of fruits, leaves , seeds, grains herbs and some time total plant spices [25] . Along with food  nutrients, foods source, plants have rich source of  bioactive phytochemicals or bio nutrients which includes preventing chronic diseases like cancer, diabetes, coronary heart disease and hyper-cholesterolaemia. Some group of phytochemicals have disease-preventing antioxidants, detoxification , immunological  and neuropharmacological activators [26]. In modern pharmacological and nutraceutical industries, phytochemicals played an important role because of wide range of its application like cofactors, modulators, inhibitors, antioxidant. The contents like carotenoids, catechins, curcumin, diosgenin , polyphenol and flavonoids have wide range against treatment of various human disease [27]. [28] documented various beneficiary effects of flavonoid  like  antioxidant, anti-inflammatory, antiallergic, anti-microbial,  effective in hepatotoxicity, cardiovascular diseases, gastric ulcer, rheumatic disease, thrombosis, memory cognition and in cardiovascular disease.  In the  present study   ethanolic extract of  seed of Ocimum sanctum, Amaranthus viridis and Cystone, the GC MS analysis conforms variety of pharmacogenic constituents  like, phytol, octadecanoic acid, Palmitic acid, oleic acid common in all three seed extract. Also Cetane and isocaryophyllene were identified. Along with precursor for vitamin E and vitamin K, phytol showed anxiolytic, metabolism-modulating, cytotoxic, antioxidant, autophagy and apoptosis inducing, antinociceptive, anti-inflammatory, immune-modulating, and antimicrobial effects  [29, 30]. [31] reported 9, 12-Octadecadienoic acid  has the property of antioxidant, anti-inflammatory and antiarthritic in his work.  Cetane number is a indicators of the quality of diesel fuel.  Variety of feedstock vegetables oils with K45 – K67are useful for the production of biodiesel [32]. [ 33] reported ?-caryophyllene has antioxidant, anti microbial and anti bacterial activities. [ 34.] reported phenols and alkaloids have antioxidants properties. [35] reported flavonoid, alkaloid, phenol, tannin and saponin have significant level of antioxidant.

CONCLUSION :

On the basis of result obtained under present investigation study revealed that, comparatively  extract of seeds of   Oscimum sanctum , Amaranthus viridis and Cystone has variety of  bioactive compound which  were screened by assay  including flavonoids, alkaloids, phenols , tannin, saponin, phytol, etc. All these compound known for biological role in the animal body as  antioxidant, antimicrobial, anticancer, anti-ulcer, anti-inflammatory and hepatoprotective. Comparatively OS, AV and CS has hexadecenoic acid chemical compound found prominently which play important role in in dissociation of calcium carbonate content. Both the phytoextract were seems to be useful for the protection of cells from accumulation of crystals and relevant pathological condition in comparison to cystone. The further advance study such as qualitative determination, purification and characterization of phytochemical constituents all extract may help to formulate herbal preparation of medical use.
