采用DPPH自由基清除能力、超氧自由基清除能力、β-胡萝卜素漂白抑制、还原力测定及抗脂质过氧化等试验方法对山竹果皮提取物及其二氯甲烷可溶部分、正丁醇可溶部分、水可溶部分进行抗氧化活性评估,同时对总酚含量进行测定。结果表明,山竹果皮提取物的各分离部位以正丁醇可溶部分的抗氧化活性最好,总酚含量也最高。因此,山竹果皮提取物正丁醇可溶部分具有极佳的抗氧化能力,有进一步开发应用的价值。
採用DPPH自由基清除能力、超氧自由基清除能力、β-鬍蘿蔔素漂白抑製、還原力測定及抗脂質過氧化等試驗方法對山竹果皮提取物及其二氯甲烷可溶部分、正丁醇可溶部分、水可溶部分進行抗氧化活性評估,同時對總酚含量進行測定。結果錶明,山竹果皮提取物的各分離部位以正丁醇可溶部分的抗氧化活性最好,總酚含量也最高。因此,山竹果皮提取物正丁醇可溶部分具有極佳的抗氧化能力,有進一步開髮應用的價值。

The antioxidant activities of the extracts from mangosteen(Garcinia mangostana)pericarp and its various fractions including the dichloromethane soluble fraction,butanol soluble fraction,water soluble fraction were assessed using various antioxidant assays,including DPPH free radical and superoxide free radical scavenging assays,β-carotene bleaching inhibition,reducing power assay and lipid peroxidation assay.In addition,total phenolic contents of these extracts were also determined.Results showed that among the various fractions,the butanol soluble fraction exhibited the strongest antioxidant activity and the content of total phenolic compounds in them was the highest.Therefore,the butanol soluble fraction in the extracts of mangosteen pericarp has excellent antioxidant activities,indicating its potential application values for further development.
