The free radical scavenging properties of six Aloe species are to be investigated in some modified chemical system. The antioxidant was purified by silica column and thin layer chromatography and analyzed by HPLC. A fraction was purified from A. brevifolia Mill showed the most effective scavenging activities on 〓 and ·OH (66. 01% and 38. 98% respectively). With the analysis of IR spectrum, UV spectrum and mass spectrum, the structure of FA was identifed as 8-C-D-glucopyranosyl-2- [2-hydroxy] propyl-5-methyl-7-hydroxychromone. Its scavenging activity on free radicals is higher than that of aloe-emodin. Its antioxidant activity may be due to the phenoxyl on glucosyl chromone which can be react with free radicals and form relatively stable free radicals.

本研究利用分别产生超氧阴离子自由基和羟自由基的化学模型体系研究比较了不同品种芦荟提取物的清除活性氧自由基的抗氧化作用，进一步利用硅胶柱结合薄层层析法和反相高压液相色谱法，从短叶芦荟叶子中首次分离了具有较强自由基清除能力（超氧阴离子自由基和羟自由基清除率分别为66.01％和38.98％）的成分FA，利用红外光谱、紫外光谱和质谱等仪器分析结果推断出该活性成分的分子结构为8-C-吡喃葡萄糖-2-[2-羟基]-丙基-5-甲基-7-羟基对氧萘酮，它的自由基清除能力高于芦荟大黄素，是一种天然抗氧化剂。
