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.
