RESUMO
From the ethanol extract of Glinus oppositifolius, collected at Phu Yen province, Viet Nam, one new triterpenoid saponin (1) and four known compounds (2-5) were isolated. By means of NMR and HR-ESI-MS analyses, their structure was elucidated as 3-O-(ß-D-xylopyranosyl-(1â3)-ß-D-xylopyranosyl)spergulagenin A or glinusopposide V (1), glinusopposide L (2), spergulin B (3), vitexin (4) and astralagin (5). Two compounds (1-2) showed weak inhibitory activity against α-glucosidase.
