| 摘要: |
| 用DPPH法测定了桑椹醋的甲醇、乙醇、丙酮、乙酸乙酯提取物的抗氧化活性,并与叔丁基对苯二酚(TBHQ)进行比较。结果表明,4种提取物对DPPH·自由基均有较强的清除作用,清除能力均高于TBHQ,其大小顺序依次为甲醇提取物>乙醇提取物>丙酮提取物>乙酸乙酯提取物》TBHQ。 |

| Abstract: |
| Antioxidant substances were extracted from mulberry vinegar with methanol ,ethanol, acetone and ethyl acetate respevtively. Their antioxidant activities were determined. The results show that the extracts of mulberry vinegar have more significant effects on DPPH radical scavenging than TBHQ. The different extracts have different antioxidant capacities, that is methanol extractant>ethanol extractant> acetone extractant>ethyl acetate extractant>>TBHQ. |
| Key words: mulberry vinegar extracts,DPPH,antioxidation, |
