[Studies on chemical constituents of herbs of Oxytropis microphylla].

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.
