摘要:
采用气相色谱质谱联用技术对小叶红叶藤挥发油的化学成分进行分析,并用DPPH?法、ABTS?+法和铁氰化钾还原法对其抗氧化能力进行研究。结果表明:从小叶红叶藤挥发油分离出221个色谱峰,共鉴定64个化合物,占挥发油总量的9572%,主要成分为dl薄荷酮(5343%)、(E)薄荷酮(1420%)、5甲基2异丙基3环己烯1酮(987%)、β萜品烯(816%)、β蒎烯(154%)、α蒎烯(118%)等。抗氧化实验中,不同浓度的挥发油对DPPH和ABTS+自由基有较好的清除能力,最高清除率分别达到6225%和6811%,但其还原能力较弱,抗氧化能力均具有明显的量效关系。
Abstract:
The constituents of the essential oils of Rourea microphylla from Guangxi were separated and identified by GCMS. The scavenging activities on DPPH? radical,ABTS?+radical and reducing power were detected by UVVis spectrophotometry. 221 compounds were isolated and 64 compounds were identified that composed about 9572% of the total essential oils. The principal chemical constituents of the essential oils were dlMenthone(5343%),(E)Menthone(1420%),2isopropyl5methyl3Cyclohexen1one(987%),βTerpinene(816%),βPinene(154%),αPinene(118%),et al. These oils possessed good scavenging activities on both DPPH? and ABTS?+ radical,the scavenging rate reaching to 6225% and 6811%,respectively,but showed low activities on reducing power. All antioxidant activity showed a concentrationeffect relationship.
