摘要
目的:建立牛黄解毒片多成分(黄芩苷、黄芩素、芦荟大黄素、大黄素)含量测定方法,完善牛黄解毒片质量控制标准。方法:以Agilent ZORBAX SB-C18(4.6mm×250mm,5μm)为色谱柱,检测波长:260nm,进样量:10μL,柱温:30℃,流速:1.0m L/min,以乙腈为流动相A,以0.1%磷酸为流动相B,进行梯度洗脱。结果:含量测定中黄芩苷、黄芩素、芦荟大黄素、大黄素的线性范围依次是5.06~202.4μg/m L、1.836~30.6μg/m L、0.196~7.84μg/m L、0.992~19.84μg/m L;相关系数R2依次是0.999 7、0.999 1、0.999 8、0.999 8;平均回收率分别是99.17%(RSD=0.72%)、97.46%(RSD=0.85%)、97.91%(RSD=1.97%)、98.23%(RSD=0.82%)(n=6)。结论:该方法准确度高,可以用于牛黄解毒片的质量评价。
Objective: To establish a method for the determination of multi- components( baicalin,baicalein,aloe emodin and emodin) in Niuhuang Jiedu tablets( NHJDT) and perfect the quality control standards. Methods: Using Agilent ZORBAX SB- C18( 4. 6 × 250 mm,5μm) as the separation column,the UV absorbance was monitored at 260 nm by injecting 10μL of the sample solution each time and the column temperature was maintained at 30℃. The flow rate was1. 0m L / min. Acetonitrile was as the mobile phase A; 0. 1% phosphoric acid was as mobile phase B for gradient elution.Results: The linear range in content determination of baicalin,baicalein,aloe emodin and emodin was followed by5. 06 ~ 202. 4μg / m L,1. 836 ~ 30. 6μg / m L,0. 196 ~ 7. 84μg / m L and 0. 992 ~ 19. 84μg / m L,the correlation coefficient R2 was in turn 0. 999 7,0. 999 1,0. 999 8 and 0. 999 8. The average recoveries were 99. 17%( RSD = 0. 72%),97. 46%( RSD = 0. 85%),97. 91%( RSD = 1. 97%),98. 23%( RSD = 0. 82%)( n = 6). Conclusion: The method is accurate and can be used to evaluate the quality of NHJDT.
