Abstract
OBJECTIVE: To isolate and identify chemical constituents of Uvaria tonkinensis var. subglabra. METHOD: The column chromatographic techniques were applied to isolate constituents, and their structures were elucidated by means of spectral data analysis including 1D and 2D NMR, IR and MS techniques. RESULT: Seven compounds were isolated and identified as subglain C (1), beta-senepoxide (2) , 2, 4-dioxohexahydro-1, 3-diazepin (3), kaempferol-3, 7-di-O-alpha-L-rhamnoside (4), anolobine (5), (-)-lyoniresinol (6) and schizandriside (7). CONCLUSION: Compound 1 was the new natural product; compounds 2-7 were isolated for the first time from U. tonkinensis var. subglabra.
