Triterpenoids from Glochidion eriocarpum
摘要
Six lupane triterpenoids (1–6), including an undescribed one, 3,23-di-O-isopropylidene-lup-20(29)-ene (1), along with two oleane triterpenoids (7, 8), were isolated from the Zhuang ethnic medicinal plant Glochidion eriocarpum. Their structures were identified based on comprehensive NMR, MS, and physiochemical data analysis. Compounds 2, 7, and 8 significantly inhibited the production of nitride oxide (NO) of the LPS-induced RAW 264.7 cells, which may be attributed to the anti-inflammatory activity of this plant.
