PRELIMINARY PHYTOCHEMICAL ANALYSIS OF LEAF EXTRACTS OF FIVE INDIGENOUS MEDICINAL TREE SPECIES FROM SEMI ARID REGIONS OF KATTAKADA, KERALA, INDIA. -

The present study reports 15 leaf extracts using three different solvents (such as Water, Acetone and chloroform) derived from commonly occurring five native medicinal tree species belonging to different families collected from the semi- arid regions of Kattakada area, Kerala, India. The plants selected for the study were Annonasquamosa, Thespesiapopulnea, Murrayakoenigii, Glyricidiasepium and Moringaoleifera. Most of these plants were reported to treat a variety of diseases in traditional system of medicine. Qualitative phytochemical screening was carried out on aforesaid extracts which revealed the presence of glycosides, phytosterols, alkaloids, phenols, oils, sapponins and flavanoids. The phytochemical studies of all the extracts in three different solvents conclude that acetone and water extracts of leaf samples had more positive results for glycosides, oils, sapponins and flavanoids. The results suggest that the leaves are a rich source of valuable primary and secondary metabolites. - See more at:
