Determination of Gallic Acid Content in Tibetan Green Fruits by High Performance Liquid Chromatography
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.
