RESUMO
Objective: To investigate the chemical constituents from the stems of Ficus auricalata. Methods: The constituents were isolated and purified by silica gel, Sephadex LH-20 column chromatography, and preparative TLC. Their structures were identified on the basis of spectral data and physiochemical characteristics. Results: Fourteen compounds were isolated from 95% ethanol extracts and identified as stigmast-4-ene-6β-ol-3-one (1), stigmast-4-ene-6α-ol-3-one (2), stigmast-4-ene-3-one (3), stigmast-5-ene-3β-ol-7-one (4), stigmast-4-ene-3, 6-dione (5), ergosterol peroxide (6), (20S)-3-oxo-hydroxytaraxastane (7), anabellamide (8), aurantiamide acetate (9) palmarumycin BG1 (10), 7-oxodehydroabietic acid (11), coniferyl aldehyde (12), S-(+)-dehydrovomifoliol (13), and 4-hydroxy-3-methoxy-benzoic acid (14). Conclusion: Compounds 2, 5, and 7-13 are reported from the plants in genus Ficus Linn. for the first time. All compounds are isolated from this plant material for the first time.
