A new triterpene from Glinus 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.
