Morphological and Physicochemical Analysis of Ipomoea cairica Leaves

In this study the preliminary pharmacognostical studies such as, morphology and transverse section of the leaf were observed. Physicochemical evaluation such as, foreign matter, moisture content, different extractive values, different ash values and fluorescence analysis were performed to explore the constants of noxious weed Ipomoea cairica. The foreign matter adulterated in one gram powder was found to be 0.15gms, alcohol soluble extractive 0.25g and chloroform soluble extractive 1.75g. Total ash value 1.02g, Acid insoluble ash value (dil. HCl) 0.85 g; Sulphated ash value (H2SO4) 0.43g; Water soluble ash value (H2O) 0.78g. Fluorescence analysis showed Orange fluorescence in concentrated sulphuric acid and 1N NaOH but no colour in Nitric acid, concentrated HCl, IN HCl and Dilute Nitric acid.
