Triterpenoids,megastigmanes and hydroxycinnamic acid derivatives from Anisomeles indica

Six triterpenoids (1–6), four megastigmanes (7–10) and five hydroxycinnamic acid derivatives (11–15) were isolated from the aerial part of Anisomeles indica (Lamiaceae). Of these components, compound 1 was identified to be a new triterpenoid with the structure of 2α,3α,19α-trihydroxyurs-12,20(30)-dien-28-oic acid based on extensive analysis of MS, 1D and 2D NMR spectroscopic data, while compounds 2–13 were obtained for the first time from Anisomeles species.
