Abstract:
OBJECTIVETo isolate and identify chemical constituents of Uvaria tonkinensis var. subglabra.
METHODThe 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.
RESULTSeven 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).
CONCLUSIONCompound 1 was the new natural product; compounds 2-7 were isolated for the first time from U. tonkinensis var. subglabra.
