Abstract:
      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.
