- Chemical constituent has been isolated from the dry acrial parts of Hedyotis philippensis. The finely choppedmaterial was bextracted with methanol then fractionated into different polarity of solvent; hexane, ethilacetate and buthanol. Needled colorless (Melting point 140-1420C) has been isolated from Ethil acetatefraction and based on its spectroscopic data particularly IR (Infra red) and ‘H-NMR (Proton of NuclearMagnetic Resonantion), it is identified as stigmasterol.
