目的考察愈风宁心分散片中葛根素的体外溶出度。方法参照《中国药典》2005年版第二部附录XC溶出度测定法第二法(桨法),以脱气蒸馏水500mL为溶出介质,温度控制在37℃±0.5℃,转速100 r/min,采用高效液相色谱法进行检测。结果葛根素在0.123 2~1.108 8μg呈良好线性关系,平均回收率98.8%,RSD为2.14%,50 min时葛根素的溶出接近90%。结论愈风宁心分散片的溶出度符合规定。
Objective To investigate the in vitro dissolution of puerarin in Yufengningxin dispersible tablets. Method Refer to “Chinese Pharmacopoeia” 2005 edition second appendix XC dissolution method second method (paddle method), with degassed distilled water 500mL dissolution medium, temperature control at 37 °C ± 0.5 °C, speed 100 r / min, using HPLC detection. Results The puerarin showed a good linear relationship between 0.123 2 and 1.108 8 μg. The average recovery was 98.8% and the RSD was 2.14%. The puerarin dissolution was close to 90% at 50 min. Conclusion The dissolution of Yufeng Ningxin dispersible tablet meets the regulations.
