Although th ere is no ethnobotanical usage recorded for this species, investigation on non-volatile isolates of this species was undertaken to help in the chemotaxonomy of the genus Heteropyxis. Heteropyxis natalensis is used by traditional healers to treat worms in stock, mental disorders and bleeding nose. It is also used during weaning and as a herbal tea. The chemical investigation of the leaves, stems and roots of Heteropyxis canescens afforded fourteen known compounds whereas that of the twigs and the roots of H. natalensis afforded ten known compounds. The current phytochemical investigation of the Psiloxyloideae has not revealed a significant variance from the chemical profile of the Myrtoideae. NAT-O10 ISOLATION AND CHARACTERIZATION OF A SPINASTEROL FROM T HE LEAVES OF MIMUSOPS ELENGI L. Wong Keng Chong, Faheem Amir and Hasnah Osman School of Chemical Sciences Universiti Sains Malaysia, 11800 Pulau Pinang, Malaysia E-mail: [email protected] Mimusops elengi L, (Sapotaceae) is an evergreen ornamental medium to big sized tree found in the tropical forests spreading from Southeast Asia to northern Australia, typically found in the intertidal zones.

The fruit exhibits antioxidant activity and the seed exhibits antibacterial activity. One steroid has been isolated from the chloroform extract and has been characterized based on its spectral data and is found to be a spinasterol (Stigmasta-7,22-diene-3-ol). 169 23rd-25th June 2010 3rd ICYC 2010 Universiti Sai...
