目的 研究大果榕Ficus auriculata茎的化学成分。方法 运用硅胶柱色谱、Sephadex LH-20凝胶柱色谱,以及制备薄层色谱等方法分离纯化,通过波谱数据和理化性质鉴定结构。结果 从大果榕茎95%乙醇提取物中分离得到14个化合物,分别鉴定为6β-羟基豆甾-4-烯-3-酮(1)、6α-羟基豆甾-4-烯-3-酮(2)、豆甾-4-烯-3-酮(3)、3β-羟基豆甾-5-烯-7-酮(4)、豆甾-4-烯-3, 6-二酮(5)、麦角甾醇过氧化物(6)、(20S)-3-oxo-20-hydroxytaraxastane(7)、伞形香青酰胺(8)、金色胡椒酰胺乙酸酯(9)、palmarumycin BG1(10)、7-羰基-脱氢枞酸(11)、松柏醛(12)、S-(+)-dehydrovomifoliol(13)、4-羟基-3-甲氧基苯甲酸(14)。结论 化合物2、5、7~13为首次从该属植物中分离得到,所有化合物均为首次从该植物中分离得到。
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.
