韭菜有机溶剂提取液的气相色谱-质谱分析及其对香蕉枯萎病菌的抑制作用研究

采用气相色谱-质谱法对韭菜茎和叶的石油醚、三氯甲烷、二氯甲烷、丙酮、乙酸乙酯有机溶剂提取液进行了检测.结果表明:有机溶剂提取液中有二甲基二硫、二甲基三硫、甲基甲烷硫代磺酸盐、二甲基酯硫磺酸、甲基2-丙烯基二硫及杂环等多种含硫化合物,另外还检出较复杂的3-乙烯基-1,2-二硫代杂环己-5-烯类物质.低温条件下,茎中石油醚...

GC-MS Analysis of Solvent Extracts from Chinesechive and Their Inhibitory Action on Banana Vascular Wilt

The components extracted from Chinesechive by different solvents,such as petroleumether,chloroform,dichloromethane,acetone and ethylacetate were detected by GC-MS.The results showed that various sulfocompounds were obtained in solvent extracts,such as dimethyl disulfide,dimethyl trisulfide,S-methyl methanethiosulfinate,sulfuric acid,dimethyl ester,disulfide,methyl 2-propenyl and heterocyclic,etc.Some rather complicated substances as 3-vinyl-12-dithiacyclohex-5-ene,were also detected.At low temperature,the kinds of detected substances at stem and leaf extracted with petroleumether,chloroform,dichloromethane,acetone and ethylacetate were 21,27,10,9,15 and 14,6,9,3,9,respectively.At high temperature,the detected substances at stem and leaf were 92,73,22,126,47 and 29,18,undetected,24,9,respectively.The kinds of main compounds at different parts of Chinesechive and different temperatures were different.The extractives from Chinesechive stem were excessive and complex.The compounds detected at high temperature were more than that at low temperature.The effect of solvent extractives on Fusarium oxysporum f.sp.cubense spore was also investigated.The result indicated that some chemical compositions existed in solvent extractives from Chinesechive with inhibitory action on the germ.
