Alkaloids and a pimarane diterpenoid from Strychnos vanprukii

Phytochemistry. 2003 Oct;64(4):897-901. doi: 10.1016/s0031-9422(03)00508-9.

Abstract

From the stem of Strychnos vanprukii, a gluco-indole alkaloid, 3,4-dehydropalicoside, and a pimarane diterpenoid, 7 beta-hydroxypimara-8,15-dien-14-one, were isolated together with four known alkaloids: palicoside, 3,4,5,6-tetradehydropalicoside, akagerine and 17-O-methylakagerine. The structures of these compounds were elucidated based on spectroscopic evidence.
