摘要: 对红树植物秋茄内生真菌Colletotrichum sp.SCSIO KcB3-2的次级代谢产物进行研究,利用硅胶柱层析,中压ODS 反相柱层析,半制备高效液相色谱仪等分离手段对其大米发酵产物进行分离纯化,利用核磁共振、质谱等波谱学手段并结合其理化性质及文献数据鉴定了14个单体化合物的结构:对羟基苯甲醛 (1),2-(4-羟苯基)乙醇 (2),2-(4-羟苯基)乙酸乙酯 (3),2-羟基-2-(4′-羟基苯基)乙醇 (4),2-甲氧基-2-(4′-羟基苯基)乙醇 (5),苯乙二醇 (6),2-氨基-3-苯基-1-丙醇 (7),对羟基苯乙酸甲酯 (8),2-(2-羟基乙基)苯酚 (9),3-chlorogentisyl alcohol (10),4-hydroxymellein (11),diaporthin (12),环(L-苯丙-L-亮)二肽 (13),环(D-苯丙-L-异亮)二肽 (14)。化合物3~14均为首次从红树植物秋茄内生真菌中分离得到。

Abstract: The secondary metabolites of strain Colletotrichum sp.SCSIO KcB3-2,an endophytic fungus obtained from mangrove plant Kandelia candel,were investigated.The extracts were purified by comprehensive chromatography methods of silica gel column,ostade-cylsilane (ODS),and semipreparative HPLC.The structures of the compounds were elucidated by spectroscopic analysis,and comparison with the reported data.Fourteen compounds were obtained and identified as 4-hydroxybenzaldehyde (1),4-(2-hydroxyethyl)phenol (2),4-hydroxyphenethyl acetate (3),1-(4-hydroxyphenyl)ethane-1,2-diol (4),4-(2-hydroxy-1-methoxyethyl)phenol (5),1-phenylethane-1,2-diol (6),2-amino-3-phenylpropan-1-ol (7),methyl 2-(4-hydroxyphenyl)acetate (8),2-(2-hydroxyethyl)phenol (9),3-chlorogentisyl alcohol (10),4-hydroxymellein (11),diaporthin (12),cyclo-(L-Phe-L-Leu) (13),and cyclo-(D-Phe-L-Ile) (14),respectively.Compounds 3-14 were isolated from endophytic fungus obtained from mangrove plant Kandelia candel for the first time.
