| 摘 要： | 通过Folin—ciocalteu比色法测定和HPLC检测分析，对壳聚糖澄清过程中沙棘果汁总酚含量以及一些酚类成分的变化进行了研究，结果显示：壳聚糖澄清对沙棘果汁中的酚类物质有所影响，总酚含量降低了17．2％，澄清后果汁中的儿茶酸、阿魏酸和香豆酸组分损失，没食子酸降低87％，槲皮素减少了62．5％，绿原酸含量变化不大。

| Abstract: | By Folin-Ciocalteu colorimetric analysis and HPLC analysis, the changes of total phenolic content and phenolic compositions in sea buckthorn juice during chitosan clarification were studied. The results showed that after clarification, the total phenolic content decreased by 17.2%, the catechin, ferulic acid and p-coumaric acid in juice were lost and gallic acid and quercetin were destroyed by 87% and 62.5% respectively, but the chlorogenic acid changed little. |
