| 摘 要： | 用干酪素法对龙井茶叶中鞣质含量进行测定。结果表明,龙井茶叶鞣质含量在2.000-11.000μg/m L范围内呈线性关系（R2=0.999 3）;样品平均加标回收率为84.6%,SD为0.226%,RSD为1.8%（n=6）。该方法准确、可靠、重现性好、精密度好,可用于龙井茶叶中鞣质含量的测定。

| Abstract: | Casein method was developed for the determination of tannin content in Longing tea. The results showed that the tannin content present a linear relationship in the range of 2.000-11.000 g/mL （R^2=0.999 3）. The sample average recovery was 84.6% with SD of 0.226% and RSD of 1.8% （n=6）. This method is reliable, reproducible and accurate, and it is well suitable for determination of tannin in Longjing tea. |
