chelonoides as shown in Table 3. The moisture content of all three species, S. chelonoides, S. tetragonum and R. xylocarpa are found to be in acceptable range. The total ash and acid insoluble ash were performed to find the residue of the extraneous matter (e.g. sand and soil) adhering to the plant surface and measures the amount of silica present, especially as sand and siliceous earth. 15 Alcohol solubility and water solubility analyses were made to estimate specific phytoconstituents present in crude drug to know the amount of active Abiraterone manufacturer constituents extracted with solvents from a given amount of medicinal plant material. 15 Therefore the percentage of total ash, acid insoluble ash, alcohol solubility and water solubility

determined are tabulated in Table 4. The total ash content of S. chelonoides and S. tetragonum is (6.2 and 7.8%) within the limits prescribed in API for S. chelonoides (Patala) whereas, R. xylocarpa shows more ash percentage (9.5%) which represents the presence of siliceous matter. As a comparative estimation, water solubility extraction values are found

to be more than alcohol solubility. It implies that water is the best solvent of extraction for the formulation than alcohol, 16 but it’s reverse to R. xylocarpa. The results obtained from physicochemical analysis for S. tetragonum is in accordance with all aspects and quality standards limits prescribed in API for S. chelonoides as Patala. The preliminary phytochemical screening of all root extracts of three species from different accessions revealed the presence of carbohydrates, saponins, proteins, flavonoids, gums and resins. Glycosides are only present in S. Gefitinib ic50 chelonoides and R. xylocarpa but not in S. tetragonum. Table 5. HPTLC technique is widely employed in pharmaceutical industry in process development, identification and detection of adulterants in the herbal products and helps in identification of pesticides content,

mycotoxins and in quality control of herbs and health foods.17 HPTLC fingerprinting studies of methanolic root extracts of S. chelonoides, S. tetragonum and R. xylocarpa from different geographic regions showed distinct Rolziracetam bands with similar and dissimilar Rf values to distinguish the species. Similarly root extracts showed the presence of 16 phytoconstituents in all the accessions of 3 study species with same and different Rf values. Among these, two compounds with Rf value 0.37 (p-coumaric acid) and 0.62 are found to be common in all three species. Likewise the bands with Rf values 0.05, 0.24, 0.39 and 0.54 are found only in S. chelonoides and S. tetragonum. Therefore, based on Rf values obtained S. tetragonum is more similar to S. chelonoides as compared to R. xylocarpa Table 6. The compound with Rf value 0.37 is identified as p-coumaric acid ( Fig. 2). The densitometric scan was performed for all tracks at 310 nm to check the identity of p-coumaric acid in root samples ( Fig. 3).
