草果精油的化学组成、抗氧化及抑菌活性研究
Chemical composition,antioxidant and antibacterial activities of the essential oil from Amomum Tsaoko
摘要
Abstract
The essential oil from Amomum tsaoko was extracted by n-hexane and analyzed by GC-MS,meanwhile,the antioxidant and antibacterial activities of the essential oil were researched.The results showed that the composition of the essential oil from Amomum tsaoko was complex and 23 constitutes were identified,the main constitutes were geraniol (29.42％),nerolidol (9.87％) and octadecenoic acid (8.62％).The essential oil from Amomum tsaoko showed a good efficiency to scavenging the DPPH and ABTS,the EC50 were 3.84mg/mL and 3.20mg/mL respectively.The antibacterial test indicated that the different concentrations of the essential oil showed definitely antibacterial activity against the five test microbe,and which showed a best efficiency for Escherichia coil,the MIC was 2.0mg/mL.关键词
