| 摘 要： | 目的]研究不同溶剂提取对无花果叶抗氧化能力的影响。方法]以不同溶剂对无花果叶进行超声提取,比较各提取物抗猪油氧化及清除DPPH（1,1-Diphenyl-2-picrylhydrazyl）和ABTS2,2-Azino-bis-（3-ethylbenzthiazoline-6-sulfonic acid）]自由基的能力。结果]各提取物对猪油的抗氧化能力为：蒸馏水提取物﹥70%乙醇提取物﹥甲醇提取物﹥乙酸乙酯提取物﹥无水乙醇提取物;对DPPH和ABTS自由基的清除能力为：蒸馏水提取物﹥70%乙醇提取物﹥甲醇提取物﹥无水乙醇提取物﹥乙酸乙酯提取物,水提物清除DPPH的IC50值为0.49 mg/ml,清除ABTS的IC50值为1.54 mg/ml。结论]无花果叶水提物具有较强的抗氧化性能,有开发功能性抗氧化剂的潜在价值。
