Quality Standard of Phyllanthus Urinaria
摘要
Abstract
Objective To establish the quality standard of Phyllanthus Urinaria and improve its quality control level. Methods Gallic acid and corilagin were selected as index ingredients. The qualitative and quantitative analyses were performed by TLC and HPLC meth-ods. Results The TLC spots of gallic acid had similar color with the reference solution at the same position. The results of quantitative analyses showed that the linear equation of gallic acid is Y=30. 715 X-0. 1729,the liner range was 0. 66-26. 40 μg/mL(r=1. 0000) and the average recovery was 97. 99%,RSD=1. 44%(n=6);the linear equation of corilagin is Y=13. 192 X+1. 4946,the liner range was 1. 79-71. 84 μg/mL(r=0. 9998),and average recovery was 95. 68 %,RSD=1. 04%(n=6). Conclusion The method is convenient,accurate,repeatable and specific,which can be used for the quality control of Phyllanthus Urinaria.关键词
