摘要
用体外化学试验和TLC比较法对拐枣用乙醇、石油醚、乙酸乙酯、正丁醇和水提取物的抗氧化作用和抗氧化成分极性强弱进行了比较分析。结果表明拐枣提取物抗氧化作用从强到弱依次为乙酸乙酯提取物>正丁醇提取物>石油醚提取物>乙醇提取物>水提取物。拐枣具有较强的抗氧化活性,抗氧化活性成分主要存在乙酸乙酯提取物中。
The antioxidant activity of extractive extracted with the EtOH,petroleum ether,EtOAc,BuOH and H2O from calligonum were relatively analyzed by the chemical test in vitro and TLC method.The result showed that the order of antioxidant activity was subsequently EtOAc extractsBuOH extracts petroleum ether extractsEtOH extractsH2O extracts.It suggested calligonum had a strong antioxidant activity,and the active ingredient mainly existed in the EtOAc extracts.
