| 中文摘要: |
| 本文采用萃取硅胶注层析分离技术，从海黏子（Sargassum kjllmanianum）中分离获得4种海藻多酚类物质，用油溶性自由基引发剂（AMVN）引发氧化亚油酸甲酯（Methyl linolenate,ML），用HPLC测定亚油酸甲酯氢过氧化物（ML－OOH）含量，以BHT和VE为对照，评价了海黍子多酚类物质的抗氧化能力。结果表明：在自由基引发剂（AMVN）作用下，获得的海藻多酚（buylated hyohoxytoluene）（0．2％）对ML氧化的抑制作用均比BHT（0．02％）好，但不如VE（0．2％）的效果好。各种海藻多酚所表现出的抗氧化能力相近。 |
| English Summary: |
| Four antioxidative phlorotannins extracted from sargassum killuanianum were isolated with silicic Gel chromatography.Their antioxidative ability to methyl linolenate (ML) was determined by testing the concentration of methyl linolenate hydroperoxide (ML OOH) in the presence of free radical initator AMVN.The results showed that the antioxidations of four phlorotannins (0.2%) are better than that of BHT (0.02%),but poorer than that of V E (0.2%).The antioxidative ability of various phlorotannins were similar. |
