摘要: 研究青霉属真菌Penicillium sp.1502 产生的次级代谢产物及其生物活性。采用正相硅胶柱、制备高效液相色谱,从该菌株发酵液的乙酸乙酯提取物中共分离得到6个化合物,通过LC-MS以及NMR鉴定为methyl asterric acid(1)、methyl 3,5-dichloroasterric acid(2)、sulochrin(3)、monochlorsulochrin(4)、dihydrogendin(5)和penipurdin A(6)。进一步测定了化合物1至化合物6对细菌、真菌及豆蚜(Aphis craccivora)的生物活性。结果表明,化合物3至化合物5对猪链球菌(Streptococcus suis)有微弱的抑菌活性,MIC均为200 μg/mL;而化合物1至化合物6对所测试的6种植物病原真菌和豆蚜无明显生物活性。

Abstract: The secondary metabolites and their bioactivities produced by Penicillium sp.1502 were investigated. Six compounds were isolated from ethyl acetate extract of the fungus fermentation broth by silica gel column chromatography and preparative HPLC, and their structures were identified as methyl asterric acid(1), methyl 3,5-dichloroasterric acid(2), sulochrin(3), monochlorsulochrin(4), dihydrogendin(5) and penipurdin A(6) by LC-MS and NMR. Compound 1 to compound 6 were further evaluated for antimicrobial and antifungal activities, and insecticidal activities against Aphis craccivora. The results showed that compound 3 to compound 5 showed weak activities against Streptococcus suis with MIC of 200 μg/mL, respectively, while compound 1 to compound 6 exhibited no obvious bioactivities against the six tested plant-pathogenic fungi and Aphis craccivora.
