Comparative Study on Antioxidant and Antimicrobial Activities of Camphor Essential Oil and Its Main Components
摘要
Abstract
The comparative study was conducted to evaluate the antioxidant and antibacterial activities of Camphor essential oil and its main components:1,8-cineole,α-terpineol,β-phellandrene,and sabinene.The results showed significant differences in the antioxidant and antibacterial activities between camphor essential oil and its four main components.When the mass concentration was 10 g/L,the 1,1-diphenyl-2-picrylhydrazyl radical(DPPH·)scavenging rates of sabinene,camphor essential oil,α-terpinol,1,8-cineole and β-phellandrene were 17.59%,14.40%,8.71%,8.05%,and 2.05%,respectively.In addition,their 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid)radical(·ABTS+)scavenging rates were 12.12%,10.34%,6.78%,6.02%,and 2.07%,respectively.The inhibition zone diameter of α-terpinol against Escherichia coli,Salmonella and Staphylococcus aureus was 15.8,17.5,and 27.8 mm,respectively.The antimicrobial diameter of 1,8-cineole and camphor oil against the three tested bacteria was between 7 and 9 mm,and β-phellandrene showed no inhibitory effect(no detectable zone of inhibition).The minimum inhibitory mass concentration(MIC)and minimum bactericidal mass concentration(MBC)values ofα-terpineol against E.coli and Salmonella were both determined to be 1.25 g/L.In contrast,the MIC and MBC values for S.aureus were found to be 0.156 g/L and 1.25 g/L,respectively.For 1,8-cineole,the MIC values against E.coli and Salmonella were both established at 2.5 g/L,while the corresponding MBC values were recorded as 5.0 g/L for both bacterial species.α-Terpineol and 1,8-cineole demonstrated significantly stronger antibacterial and bactericidal activity compared to camphor essential oil,while sabinene and β-phellandrene showed negligible antimicrobial activity.关键词
