Composition Analysis and Antibacterial Activity of the Essential Oil from Cymbopogon citratus
摘要
Abstract
In order to investigate the essential oil from Cymbopogon citratus and the antimicrobial activities of its predominant element,to provide a theoretical basis for further exploitation of plant pesticide,this paper extracted essential oil from Cymbopogon citratus by steam distillation and analyzed the component of essential oil by gas chromatography coupled with mass spectrometry (GC-MS).Total 26 components were identified representing 93.57％ of the essential oil,including citral (75.73％),the most predominant compound,terpenoids having the highest relative content (93.13％).Besides,aldehyde took the highest proportion of essential oil by 76.35％,followed by alcohol,ketone,cyclic ether and ester.The bacteriostatic activities of Cymbopogon citratus essential oil and citral against 4 important pathogenic fungi from vegetables and fruits Pythium,Botrytis cinerea,Alternaria and Fusarium oxysporum were tested in vitro.The results indicated that among these 4 pathogens,both essential oil from Cymbopogon citratus and citral had the best antibacterial effect against Pythium aphanidermatum,especially the effect of citral is 35.30％ higher than that of the essential oil from Cymbopogon citratus.关键词
