目的:通过体外抗氧化活性测试评价猫须草醇提取物的抗氧化活性。方法以DPPH、ABTS自由基清除,FRAP还原法及金属螯合能力这三个体系的体外抗氧化活性进行分析。结果猫须草醇提取物对DPPH自由基的清除率( IC50为13.45μg? mL -1)高于BHT( IC50为46.78μg? mL -1),但低于Trolox (IC50为6.08μg? mL -1),而对于ABTS自由基的清除率(IC50为6.06μg? mL -1)则高于 BHT(IC50为12.49μg? mL -1)和Trolox (IC50为6.45μg? mL -1);猫须草醇提取物(FRAP为516mmol? L-1)具有较强的还原能力。此外,猫须草醇提取物的金属螯合能力(8.35%)高于柠檬酸(3.86%),低于EDTA(48.32%),具有一定的金属螯合能力。结论通过体外抗氧化活性检测,得出猫须草醇提取物具有较强的清除DPPH和ABTS自由基的能力,且随提取物质量浓度增加而增加。
目的:通過體外抗氧化活性測試評價貓鬚草醇提取物的抗氧化活性。方法以DPPH、ABTS自由基清除,FRAP還原法及金屬螯閤能力這三箇體繫的體外抗氧化活性進行分析。結果貓鬚草醇提取物對DPPH自由基的清除率( IC50為13.45μg? mL -1)高于BHT( IC50為46.78μg? mL -1),但低于Trolox (IC50為6.08μg? mL -1),而對于ABTS自由基的清除率(IC50為6.06μg? mL -1)則高于 BHT(IC50為12.49μg? mL -1)和Trolox (IC50為6.45μg? mL -1);貓鬚草醇提取物(FRAP為516mmol? L-1)具有較彊的還原能力。此外,貓鬚草醇提取物的金屬螯閤能力(8.35%)高于檸檬痠(3.86%),低于EDTA(48.32%),具有一定的金屬螯閤能力。結論通過體外抗氧化活性檢測,得齣貓鬚草醇提取物具有較彊的清除DPPH和ABTS自由基的能力,且隨提取物質量濃度增加而增加。

OBJECTIVE To evaluate the antioxidant activity of alcohol extracts from clerodendranthus apicatus through the vitro antioxidant activity test .METHODS The vitro antioxidant activity was analyzed through the fol-lowing aspects:the DPPH,ABTS radical scavenging ,FRAP reduction and met al chelating ability.RESULTS The scavenging rate that the alcohol extract from clerodendranthus spicatus on the DPPH radical ( IC50 13.45μg? mL-1 ) was higher than that of BHT ( IC50 46.78μg? mL -1 ) ,but lower than that of Trolox ( IC50 6.08μg? mL-1 ) ,while for the ABTS radical,the scavenging rate (IC50 6.06μg? mL-1) was higher than that of BHT (IC50 12.49μg? mL-1) and Trolox (IC50 for 6.45μg? mL-1);the alcohol extract from clerodendranthus spicatus (FRAP 516mmol? L-1) had a strong reducing capacity.In addition,the met al chelating ability of the alcohol extract from clerodendranthus spicatus (8.35%) was higher than that of citric acid (3.86%),but lower than that of EDTA (48.32%),with a certain met al chelating ability .CONCLUSION Through the vitro antioxidant activity test ,it is concluded that the alcohol extract from clerodendranthus spicatus has a strong ability ,which increases with the extract concentration ,to scavenge the free radicals of DPPH and ABTS .
