摘要
为了解藏青果中有效成分没食子酸的含量,采用高效液相色谱法,开展精密度实验、稳定性实验、重现性实验、加样回收率实验等,并测定藏青果中没食子酸的含量.结果表明,没食子酸在0.12～0.40 μg范围内线性关系良好,试验仪器稳定,样品稳定性、实验重现性较好,样品回收率高,并且藏青果中没食子酸的平均含量为 101.40 μg·g-1,表明藏青果中没食子酸含量较低.
Abstract
In order to understand the content of gallic acid in Tibetan green fruit,precision test,stability test,reproducibility test and recovery test were carried out by high performance liquid chromatography,and the content of gallic acid in Tibetan green fruit was determined.The results showed that the linear relationship of gallic acid was good in the range of 0.12～0.40 μg,the test instrument was stable,the sample stability and experimental reproducibility were good,and the sample recovery was high.Moreover,the average content of gallic acid in Tibetan green fruit was 101.40 μg·g-1,indicating that the content of gallic acid in Tibetan green fruit was low.
