Abstract:
OBJECTIVETo study the chemical constituents of Oxytropis microphylla.
METHODThe compounds were isolated and purified by various column chromatographic techniques and their structures were elucidated on the basis of spectral analysis (EI-MS, 1H-NMR, 13C-NMR).
RESULTEight compounds were isolated and identified as kaempferol (1), baicalein (2), 5-hydroxy-7, 8, 4'-trimethoxyflavone (3), stigmasterol (4), stigmast-4-en-3beta-ol (5), beta-sitosterol (6), lupenol (7), dehydrocostus lactone (8).
CONCLUSIONAll compounds were isolated for the first time from this plant, compounds 2, 3, 5, and 8 were isolated for the first time from this genus.
