Objective:
To study the chemical constituents from the rhizome of Rabdosia flavida.
Methods:
The compounds were isolated and purified by various chromatographic methods, and their structures were elucidated on the basis of spectral data and physicochemical properties.
Results:
Ten compounds were obtained from ethyl acetate fraction of the 70% acetone extract of Rabdosia flavida rhizome and identified as ferruginol (1), dehydrocostuslactone (2), taraxasterol (3), oleic acid (4), ursolic cid (5), coniferyl aldehyde (6), oleanolic acid (7), 6,12, 15-trihydroxy-5, 8,11, 13-abietetra-7-one (8), 5α, 8α-epidioxyergosta-6,22-dien-3β-ol (9), and daucosterol (10).
Conclusion:
All the compounds are isolated from Rabdosia flavida for the first time.
