Abstract

General phytochemical screening on the bark of Kopsia singapurensis Ridl. (Apocynaceae) revealed the presence of steroids, terpenes and alkaloids. Stigmasterol 1 was isolated from the hexane crude extract of this species. The structure of this compound was elucidated based on spectroscopic analysis such as ultra-violet (UV), infrared (IR), gas chromatography - mass spectroscopy (GC-MS), nuclear magnetic resonance (NMR), and involving also comparison with data from the literature. This compound has never been reported from this species
