【摘要】 目的:建立麻黄汤(麻黄、甘草、桂枝和苦杏仁)配方颗粒剂的HPLC指纹图谱,通过与传统汤剂进行比较,为麻黄汤配方颗粒剂的可行性提供依据。方法:采用反相高效液相色谱法,流动相为甲醇-0.01 mol/L磷酸二氢钾水溶液(磷酸调pH=3)进行梯度洗脱。结果:确定了26个共有峰,得到了以甘草次酸为参照的相对峰面积值。结论:两者主要指标成分的相对含量差别不大,麻黄汤配方颗粒剂有其合理性。更多还原

【Abstract】 AIM: To study the difference in main chemical composition and content between Mahuangtang Herb Ephedrae;Radix et Rhizoma Gly Cyrrhizae;Ramulus Cinnamoni;Semen Armeniacea Amarum;dispensing granule and its standard decoction. METHODS: RP-HPLC was used to create fingerprinits with MeOH-0.01 mol/L KH₂PO₄（H₃PO₄ adjusted pH=3）,a gradient eluting agent. RESULTS: 26 co-possessing peaks were indicated,the retention time and relative peak area were obtained. CONCLUSION: The difference between Mahuangtang dispensing granule and standard decoction is not obvious,the former is rational.更多还原
