HPLC Study on HPLC Characteristic Spectrum of Huoxiang(Herba Agastachis)Eliminating Summer-heat Soft Capsule

To establish HPLC characteristic spectrum of Huoxiang(Herba Agastachis)Eliminating Summer-heat Soft Capsule.Chromatographic separation was performed on Tech Mate C18-ST(5 um,4.6×250 nm)column by Agilent 1260 high performance liquid chromatograph,eluted with acetonitrile and 0.05%phosphoric acid in a gradient elution at a flow rate of 1.0 mL∙min-1.The detection wavelength was set at 270 nm.Hesperidin was selected as the reference peak to calculate the RSD of the relative retention time.Precision,stability and reproducibility were investigated as well.80 different samples from 5 manufacturers were included in this study.The HPLC characteristic spectrum of Huoxiang Eliminating Summer-heat Soft Capsule was constructed with 11 specific chromatographic peaks in 80 samples.The method is accurate,reliable and with good reproducibility,and could overall control the quality of Huoxiang Eliminating Summerheat Soft Capsule.

高效液相色谱法同时测定加味藿香正气软胶囊中橙皮苷、厚朴酚、和厚朴酚和甘草苷的含量

目的:建立高效液相色谱法同时测定加味藿香正气软胶囊中橙皮苷、厚朴酚、和厚朴酚和甘草苷的方法。方法:采用Kromasil C18色谱柱(250 mm×4.6 mm,5μm),以水-甲醇为流动相梯度洗脱,流速1.0 mL·min-1,检测波长287 nm。结果:橙皮苷、厚朴酚、和厚朴酚、甘草苷分别在4.47-178.70μg·mL-1、3.42-136.96μg·mL-1、3.49-139.48μg·mL-1、3.92-157.20μg·mL-1范围内与峰面积呈良好线性关系(r=0.999 9),平均回收率分别为99.48%、99.05%、99.57%、99.79%。结论:该方法准确、灵敏、专属性强,为加味藿香正气软胶囊质量标准提高奠定了基础。

藿香正气滴丸治疗感冒风寒兼湿滞证的随机对照试验

目的评价藿香正气滴丸治疗感冒风寒兼湿滞证(普通感冒)的有效性和安全性。方法试验采用随机、双盲双模拟、阳性药物平行对照、多中心临床再评价试验设计,共纳入480例受试者,随机分为试验组(藿香正气滴丸+藿香祛暑软胶囊模拟剂)360例和对照组(藿香祛暑软胶囊+藿香正气滴丸模拟剂)120例,疗程3天。结果中医主症泄泻疗效:试验组愈显率86.1%,总有效率96.1%,对照组愈显率69.2%,总有效率84.6%;中医证候疗效:试验组愈显率87.5%,总有效率98.5%,对照组愈显率69.2%,总有效率91.5%。两组间比较其差异均有统计学意义(P<0.05),说明藿香正气滴丸治疗感冒风寒兼湿滞证(普通感冒)的疗效优于藿香祛暑软胶囊。在用药过程中未发现该药的不良反应。结论藿香正气滴丸治疗感冒风寒兼湿滞证(普通感冒)安全有效。
