摘要
目的:测定龙芍续骨胶囊中芍药苷的含量,并考察中性氧化铝层析纯化对芍药苷含量测定的影响。方法:采用高效液相色谱法测定芍药苷含量,以中性氧化铝纯化富集芍药苷。液相条件:Kromasil-C18(250mm×4.6 mm,5μm)色谱柱;以甲醇-水(28∶72)为流动相,流速为1.0 m L·min-1,检测波长为230 nm,柱温30℃。结果:芍药苷在0.048~1.68μg范围内与峰面积呈良好线性关系(r=0.9996),精密度和稳定性试验的RSD分别为0.31%和0.86%,平均回收率为99.19%,RSD为0.97%(n=6)。结论:本方法简单,稳定易行,灵敏度高,可控性强,重复性好,可用于龙芍续骨胶囊中芍药苷的含量测定。建议在本品质量标准中规定每1 g内容物含白芍以芍药苷(C23H28O11)计,不得少于0.38 mg。
Objective:To establish a method for determination of paeoniflorin in Longshao Xugucapsule and study on the determination of neutral alumina chromatography purification effect of paeoniflorin. Method:Determination of paeoniflorin content by HPLC,purification and concentration of paeoniflorin in neutral alumina. The HPLC method was carried out on Cromasil C18(150 mm×4.6 mm,5 μm)column using Methanol-water(28∶72)as mobile phase,the flow rate was 1.0 m L·min-1,The detection wavelength was 230 nm,detection wavelength was 230 nm.The tempterature of column was 30℃. Result:Paeoniflorin in 0.048~1.68 μg range showed a good linear relationship(r=0.9996);Precision and stability test of RSD were 0.31% and 0.86%,the average recovery rate of(n=6)99.19%,RSD 0.97%. Conclusion:The method is simple,stable and easy operation,high sensitivity,strong controllability,repeatability,and can be used for content determination of paeoniflorin in long shao xu gu capsule. Recommendations are provided for every 1 g content of paeoniflorin in Radix Paeoniae Alba by containing the quality standard of this product(C23H28O11)meter,shall not be less than 0.38 mg.
