海滩植物厚藤（Ipomoea Pes-caprae）抗氧化活性研究

Extracts from Ipomea pes-caprae (Linn.) Sweet in ASE and Study on Antioxidant Activity

摘要:

采用ASE加速溶剂萃取技术快速制备厚藤活性提取物，并以DPPH法对厚藤茎叶不同溶剂提取物抗氧化活性进行评价。抗坏血酸抗氧化能力>乙酸乙酯提取物抗氧化能力>乙醇提取物抗氧化能力>甲醇提取物抗氧化能力>石油醚提取物抗氧化能力，其IC50值分别为0.2034 mg/mL、0.8362 mg/mL、0.8688 mg/mL、1.8675 mg/mL、6.6283 mg/mL。结果显示厚藤茎叶提取物具有一定的抗氧化活性，且以乙酸乙酯为提取溶剂时，效果最佳。

Abstract:

The Ipomea pes-caprae (Linn.) Sweet leaves extracts were extracted with different polar solvents by ASE. The antioxidant activity of different extracts were evaluated by DPPH assay. The antioxidant activity of ascorbic acid > ethyl acetate extract > ethanol extract > methanol extract > petroleum ether extracts, its IC50 values were 0.2034 mg/mL, 0.8362 mg / mL, 0.8688 mg/mL, 1.8675 mg/mL and 6.6283 mg/mL. The results showed the Ipomea pes-caprae (Linn.) Sweet leaves extracts had an antioxidant activity, and ethyl acetate extract was highest in all extracts.
