摘　　要：AIM:To investigate the chemical constituents of Glinus oppositifolius.METHODS:The compounds were isolated by silica gel chromatography.The structure of the new triterpene was elucidated by extensive 1D and 2D NMR spectroscopy.RESULTS:The dichloromethane extract of the air-dried leaves of Glinus oppositifolius afforded a new triterpene,oppositifolone(1),spinasterol(2),squalene(3) and lutein(4).The structure of 1 was elucidated by NMR spectroscopy,while 2-4 were identified by comparison of their 13C NMR data with those reported in the literature.CONCLUSION:A new triterpene was isolated from G.oppositifolius.AIM： To investigate the chemical constituents of Glinus oppositifolius. METHODS： The compounds were isolated by silica gel chromatography. The structure of the new triterpene was elucidated by extensive 1D and 2D NMR spectroscopy. RESULTS： The dichloromethane extract of the air-dried leaves of Glinus oppositifolius afforded a new triterpene, oppositifolone （1）, spinasterol （2）, squalene （3） and lutein （4）. The structure of 1 was elucidated by NMR spectroscopy, while 2-4 were identified by comparison of their 13C NMR data with those reported in the literature. CONCLUSION： A new triterpene was isolated from G oppositifolius.
