YANG Bing-huo, TAN Xuan-zhong, LANG Yong-ying. Quality Standard of Compound Yiqi Gutuo Granules[J]. Chinese journal of experimental traditional medical formulae, 2015, 21(21): 70-73. DOI: 10.13422/j.cnki.syfjx.2015210070.
Objective: To establish the quality standard of Yiqi Gutuo granules. Method: Qualitative identification of Astragalus
Angelica and Citrus Aurantium in the formula was carried out by thin-layer chromatography (TLC). HPLC method was used for the determination of astragaloside and ferulic acid contents. Result: TLC spots were clear and well-separated without negative interference. The linear range of calycosin glucoside
ferulic acid were 0.012 0-0.120 and 0.112 0-1.120 g·L-1
respectively
with good linear relationship with the peak area integral value. The average recoveries were 98.54% and 97.79%
respectively. RSD were 2.2% and 1.9%
respectively. Conclusion: The qualitative and quantitative method is simple
convenient
accurate and reliable with good precision. It can be used for the quality control of Yiqi Gutuo granules.
