Triterpenoids from Glochidion eriocarpum

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.
