| 摘要: |
| 采用不同溶剂从七叶树中提取有效成分，并用乙酸乙酯萃取，将所制得提取物干品定量加入油脂中，通过对强化保存期间过氧化值（POV）的测定表明，以体积分数70％乙醇为溶剂的提取物的抗氧化性能最优，在油脂中的添加量为0.08％时效果最佳，且超过0.02％的BHT，化学预试法和薄板层析法补步鉴定出，体积分数70％乙醇提取物中含有酚类及鞣质，有机酸，黄酮类化合物，植物甾醇等活性成分。 |

| Abstract: |
| The extracts containing oxidation resisting constituents were obtained from the leaves of Aesculus Chinensis Bunge by different extracting methods.The activities of oxidation resistance of the extracts were measured by using rape oil as a substrate.It was found that the extracts obtained by 70% ethanol with an added amount of 0.08% showed the highest activity and better than 0.2% BHT. The extracts contain phenolic compounds,tannins,organic acids,flavonoids, phytosteriols,etc. |
