Objective Establishment of quality standards for Xiaoyan Muniziqi granules(XYMNZQG).Methods The qualitative identification of Cuscutae Semen and Dracocephalum moldavia in the preparation was carried out,and the content of hyperin and tilianin in the preparation was determined.Results The qualitative results of Cuscutae Semen and Dracocephalum moldavia in XYMNZQG were clear.The linear ranges of hyperin and tilianin were 11.932 2-95.457 6 μg·mL-1(r=0.999 9)and 25.281 78-202.254 24 μg·mL-1(r=0.999 4),respectively.The average recoveries were 99.11%and 99.52%,with RSDs of 0.47%and 0.72%(n=6).Conclusion The established quality control method is simple,reliable,and specific,and can be used for the quality control of XYMNZQG.
