title: Four new trimeric stilbene glucosides from Welwitschia mirabilis.
abstract: Four new trimeric stilbene glucosides, mirabilosides C-F (1-4) were isolated from MeOH extract of stem and root of Welwitschia mirabilis (Welwitschiaceae) along with three known stilbenoids, resveratrol (5), gnemonoside B (6), and gnetin G (7). The structures of these compounds were elucidated by spectroscopic methods.
