摘要
目的对红树植物海莲内生真菌菌丝体提取物的乙酸乙酯萃取部分进行化学成分研究。方法采用硅胶柱色谱等分离手段,利用理化数据和各种波谱分析方法,结合文献对照,对海莲内生真菌penicilium sp.091402菌丝体中化学成分进行分离鉴定。结果与结论从海莲内生真菌penicilium sp.091402菌丝体乙酸乙酯萃取部分分离得到6个化合物,分别鉴定为:(3β,22E)-麦角甾-5,7,22-三烯-3-醇(1),(3β,5α,8α,22E)-5,8-过氧麦角甾-6,22-二烯-3-醇(2),(3β,5α,6α,7α,22E)-5,6-环氧走角甾-8(14),22-二烯-3,7-二醇(3),(3β,5α,6β,22E)-麦角甾-7,22-二烯-3,5,6-三醇(4),soyasapogenol B(5)和citrinin H2(6)。
Objective To study the chemical constituents from ethanol extracts of endophytic fungus Penicillium sp. 091402 of Mangrove plant Bruguiera sexangula. Method The compounds were separated by column chromatography, and their structures were elucidated based on chemical and spectral analysis. Results and Conclusion Six compounds were isolated from the ethyl acetate fraction of mycelia. Their structures were identified as ergosterol (1), ergosterol peroxide (2), ( 3β, 5a, 6a, 7a, 22E)-5, 6-epoxyergosta-8 ( 14 ), 22-diene-3, 7-diol (3), (3β, Sa,6β,22E)-ergosta-7,22- diene-3,5,6-triol (4), soyasapogenol B (5) and citrinin H2 (6).
