摘要: 对红树植物木榄内生忽视拟盘多毛孢菌Pestalotiopsis neglecta的次级代谢产物进行研究。利用硅胶柱层析,Sephadex LH-20凝胶柱层析,半制备高效液相色谱仪等分离手段对木榄内生P.neglecta的提取物进行分离纯化,并利用各种波谱方法,结合文献对照,确定化合物结构。从提取物中分离得到7个化合物,经鉴定为麦角甾-6,22-二烯-5α,8α-环二氧-3-醇(1),麦角甾-4,6,8(14),22-四烯-3-酮(2),24β-乙基胆甾-4-烯-3β-醇(3),24-降胆甾-22-烯-3β-醇(4),麦角甾-5,7,22-三烯醇(5),胆甾醇(6),24-甲基胆甾-5-烯-3β,7α-二醇(7)。这7个化合物均为首次从木榄内生真菌P.neglecta中分离得到。

Abstract: To investigate the secondary metabolites from endophytic fungus Pestalotiopsis neglecta which was isolated from the leaves of mangrove plant Bruguiear gymnorrhiza. A variety of chromatographic purification methods like CC,PTLC,HPLC,and Sephadex LH-20 were applied and seven compounds were isolated. Their structures were identified according to their physicochemical properties and spectral data,they are as follows:1,6,8-trihydroxy-3-(hydroxymethyl) anthraquinone (1), ergosta-4,6,8(14),22-tetraen-3-one (2), 24β-ethylcholest-4-en-3β-ol (3), 24-norcholesta-22-en-3β-ol (4),ergosta-5,7,22-trienol (5),cholesterol (6),24-methylcholest-5-en-3β,7α-diol (7).These compounds are isolated from endophytic fungus P.neglecta for the first time.

Key words: mangrove plant, Bruguiear gymnorrhiza, endophytic fungus, Pestalotiopsis neglecta
