Chemical Constituents from Myrsine africana L.

Three new compounds, myrsinoside A (=2,4‐dihydroxy‐6‐methylphenyl β‐D‐(6′‐galloyl)glucopyranoside; 1), myrsinoside B (2,4‐dihydroxy‐6‐methylphenyl β‐D‐glucopyranoside; 2), and (3β,16α,20α)‐3,16,28‐trihydroxyolean‐12‐en‐29‐oic acid 3‐{O‐β‐D‐glucopyranosyl‐(1→2)‐O‐[β‐D‐glucopyranosyl‐(1→4)]‐α‐L‐arabinopyranoside} (3), along with four known compounds, were isolated from the stems of Myrsine africana L. The structures of these new compounds were elucidated on the basis of spectroscopic analysis, including 1D‐ and 2D‐NMR and ESI‐MS techniques, and chemical methods.
