Four new triterpene glucosides fromSalacia cochinchinensis Lour
Natural Product Research(2022)
摘要
Four new triterpene glucosides (1–4) were isolated from the 90% ethanol extract ofSalacia cochinchinensis, together with five known compounds (5–9). The structures of the new compounds were elucidated by comprehensive spectroscopic analysis including HRESIMS, IR, 1 D and 2 D NMR analysis. All isolates were assayed for their α-glucosidase inhibitory activity. Compound9 showed remarkable α-glucosidase inhibitory activity with an IC50 value of 0.31 μM, and the triterpene glycosides (1–5) exhibited moderate α-glucosidase inhibitory activity.
