郁金茎叶提取物抑杀植物病原真菌活性研究与GC/MS分析
Antifugal activity and GC/MS analysis of extracts from Curcuma phaeocaulis stems and leaves against plant pathogenic fungi
摘要
Abstract
The ethanol extractum of the stems and leaves from C.phaeocaulis had been prepared,then it was not only extracted by n-Hexane,ethylacetate,and methanol,but also the ethanol and n-Hexane extracts were chemically analyzed by GC/MS.Results indicated that both the ethanol and n-Hexane extracts showed well antifungal activities against pathogenic fungi including Fusarium graminearum,Phoma wasabiae,Sclerotinia sclerotiorum and Botrytis cinerea.Relative antifungal activities of three extracts,were compared and the yield of nHexane was 64.68％,higher than those of others while its antifungal activity was also the highest.The G-C/MS results showed that there were 11 components increased and the highest components were curcumenol (24.46 ％) and hexadecanoic acid,methyl ester (13.84 ％) in n-Hexane extract.There were 28 components in ethanol extractum and 23 ones in n-Hexane extractum identified by GC/MS analysis.关键词
