Pharmacognostic Studies on Rumex vesicarius

Rumex vesicarius is a branched succulent herb which belongs to the family Polygonaceae and is distributed in India. The whole plant is medicinally important and cures several diseases. Therefore in this context the detailed pharmacognostic study of various parts like leaf,stem,petiole and root has been carried out with the aim to establish its Pharmacognostical standards. The parameters selected were microscopical studies, proximate analysis, fluorescence analysis and preliminary phytochemical screening including thin layer chromatographic analysis.The microscopical studies of leaf,stem and root revealed the presence of sessile glandular trichomes, spiral and scalariform xylem vessels.In physico-chemical evaluation the ash values and extractive values were studied. Fluorescence analysis performed showed the wide range of fluorescence colours for the crude powder as well as the extracts. The powder of R.vesicarius was successively extracted with hexane,benzene,chloroform,ethylacetate,ethanol and water for the identification of the best solvent. Preliminary phytochemical screening was carried out for all the extracts and maximum chemical constituents was observed in the ethanolic extract. The inorganic elementary analysis performed revealed the presence of sodium,chloride and iron.The TLC studies performed produced fluorescent spots for the solvent systems selected for flavonoids,steroids and anthraquinones .
