Abstract

Eight new indole alkaloids, alpneumines A-H (1-8) were isolated from the Malaysian Alstonia pneumatophora (Apocynaceae) and their structures were determined by MS and 2D NMR spectroscopic methods. Alpneumines E and G (5 and 7), vincamine, and apovincamine showed anti-melanogenesis in B16 mouse melanoma cells. Copyright 2010 Elsevier Ltd. All rights reserved.
