摘要
目的:对碧江乌头内生真菌Alternaria solani次生代谢产物进行研究。方法:将内生真菌Alternaria solani发酵产物用甲醇提取,回收甲醇至浸膏状,浸膏用乙酸乙酯萃取,得粗提物。粗提物用各种柱色谱进行分离纯化,经光谱数据(~1H-NMR,^(13)C-NMR,MS)进行结构鉴定。结果:分离得到12个化合物,分别鉴定为:(22E,24R)-Ergosta-4,6,8(14),22-tetraen-3-one(1),1,3-二油酸甘油酯(2),5-(3',3'-Dimethylallyloxy)-3-methoxy-4-methylphthalide(3),拟盘多毛孢H2-倍半萜内酯(4),过氧麦角甾醇(5),7-dehydroxyl-zinniol(6),麦角甾-7,22-二烯-3β,5,6-三醇(7),9-octadecenoic acid-2',3'-dihydroxy propyl ester(8),8-甲基塔拉胺(9),查斯曼宁(10),滇乌碱(11),crassicauline A(12)。结论:从内生真菌Alternaria solani中分离得到12个化合物,其中化合物9~12均为首次分离得到。
Objective:To study the secondary metabolites of endophytic fungus Alternaria solani from Aconitum Tsaii. Methods:The endogenous fungui fermentation product was extracted by methanol followed by recycling methanol to obtain the extract, and the ex-tract was extracted by ethyl acetate to obtain the crude extract. The compounds were isolated and purified by column chromatography and identified based on the spectral analysis ( MS, 1 H-NMR and 13 C-NMR) . Results:Totally 12 compounds were isolated from A. so-lani and characterized as (22E, 24R)-Ergosta-4, 6, 8 (14), 22-tetraen-3-one (1), 1,3-Diolein (2), 5-(3', 3'-Dimethylallyloxy)-3-methoxy-4-methylphthalide (3), pseudomonas aeruginosa H2-sesquiterpene lactone (4), ergosterol peroxide (5), 7-dehydroxyl-zinni-ol (6), ergosterol-7, 22-diene-3β, 5,6-triol (7), 9-octadecenoic acid -2',3'-dihydroxy propyl ester (8), 8-O-Methyltalatisamine (9), Chasmanine (10), yunaconitine (11) and crassicauline A (12). Conclusion:Totally 12 compounds are isolated from the endo-phytic fungus Alternaria solani, and four of them are isolated for the first time.
