Objective:
To study the chemical constituents of Oxytropis microphylla.
Method:
The 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).
Result:
Eight 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).
Conclusion:
All 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.
