摘要: 采用活性追踪的方法,对一株盐生海芦笋来源真菌Salcoli6发酵产物中的抗肿瘤活性成分进行分离和鉴定。利用溶剂萃取、硅胶柱色谱及制备HPLC等分离手段从发酵产物中分离得到7个化合物,通过理化性质分析及波谱学方法鉴定其化学结构分别为枝孢菌素(1)、异枝孢菌素(2)、2-乙酰基喹唑啉(3)、萘满酮(4)、3-羟基-2-甲级色原酮(5)、3-甲级异苯并呋喃(6)、对-羟基苯乙酸(7);以SRB法评价化合物的抗肿瘤活性,化合物3、4和7对p388细胞具有强的细胞毒活性,IC50值分别为12、24μg/mL和6μg/mL,其他化合物没有活性。

Abstract: The anti-tumor components were isolated and identified from fermentation products of fungus Salcoli6 derived from Salicornia herbacea by bioassay-guided method. Seven compounds were isolated sequentially by solvent extraction, silica gel column chromatography and preparative HPLC. Their structures were identified as cladosporin (1), isocladosporin (2), naphthalenone (3), 2-acetyl-quinazoline (4), 3-hydroxy-2-methyl-chromen (5), 3-methylisobenzofuran (6) and p-hydroxyphenyl-acetic acid (7) by physicochemical properties and spectral analysis, respectively. The anti-tumor activity of the compounds was evaluated by SRB method. Compounds 3, 4 and 7 revealed cytotoxicity with IC50 of 12, 24 and 6μg/mL against p388 cell line, respectively; however, other compounds were inactive.

Key words: Salicornia herbacea-derived fungus, fermentation product, anti-tumor activity
