Abstract

The antioxidant activities of four Lamiaceae plants, Salvia viridis L., Salvia multicaulis Vahl, Stachys byzantina C. Koch and Eremostachys laciniata (L.) Bunge have been determined by using 1,1-diphenyl-2-picrylhydrazyl (DPPH) as well as by flow injection analysis-luminol chemiluminescence (FIA-CL). All extracts were shown to possess a significant scavenger activity against DPPH free radical and an inhibitory effect on H2O2- or HOCl-luminol chemiluminescence. The extracts scavenged 50% of DPPH radical ranging in the following descending order: Salvia viridis > Stachys byzantina > Salvia multicaulis > Eremostachys laciniata. The most potent extract on H2O2-induced peak chemiluminescence was that of Salvia viridis and on HOCl-induced peak chemiluminescence was that of Stachys byzantina. The results concluded that the extracts have a potential source of antioxidants of natural origin.

摘要

通过使用1,1-二苯基-2-苦基肼（DPPH）以及流动注射分析-鲁米诺化学发光法（FIA-CL），测定了四种唇形科植物—— 绿花鼠尾草（Salvia viridis L.）、多茎鼠尾草（Salvia multicaulis Vahl）、绵毛水苏（Stachys byzantina C. Koch）和裂叶沙穗（Eremostachys laciniata (L.) Bunge）的抗氧化活性。结果表明，所有提取物均对DPPH自由基具有显著的清除活性，并对H2O2或HOCl-鲁米诺化学发光具有抑制作用。提取物清除50% DPPH自由基的能力排序如下（从高到低）：绿花鼠尾草 > 绵毛水苏 > 多茎鼠尾草 > 裂叶沙穗。对H2O2诱导的峰值化学发光抑制作用最强的提取物来自绿花鼠尾草，而对HOCl诱导的峰值化学发光抑制作用最强的提取物来自绵毛水苏。结果表明，这些提取物是天然抗氧化剂的潜在来源。
