Steroids and polyketides from Uvaria hamiltonii stem bark

Kamrun Nahar Asha et al. Acta Pharm. 2004 Mar.

Abstract

Two known steroids, stigmasterol and 6b-hydroxystigmasta-4,22-dien-3-one (1) and two unusual polyketides, cis-4-hydroxymellein (2) and trans-4-hydroxymellein (3) were isolated from the stem bark of Uvaria hamiltonii. The structures of the compounds were elucidated independently by high-resolution 2D-NMR techniques and confirmed by comparison with previously reported values.
