Abstract:Objective To improve the quality control standard of Toutongning Capsule. Methods Adopting microscopic identification to make a qualitative identification of Gastrodiae Rhizoma.Using HPLC to determine Astilbin of Smilacis Glabrae Rhizoma.C18 column was used with a mobile phase of acetonitrile-01%glacial acetic acid.The flow rate was 10 mL·min-1.The detection wavelength was at 291nm.Results Gastrodiae Rhizoma could be detected by microscopic identification.The average recovery of Astilbin was 10014% with RSD of 18%Conclusion Microscopic identification characteristic is good, easy to identify.The HPLC method is simple, good reproducibility, and can effectively control the quality of Toutongning Capsule.

头痛宁胶囊的现行标准为国家药品标准WS-11211(ZD-1211)-2002,处方由土茯苓、天麻、制何首乌、当归、防风、全蝎等组成,具有熄风涤痰、逐瘀止痛的功效,临床用于偏头痛,紧张性头痛属痰瘀阻络症。方中天麻息风止痉,平抑肝阳,祛风通络[1],广泛用于头痛眩晕的治疗,为方中主药之一。方中天麻为生药粉投料,且天麻的显微特征明显,采用显微鉴别操作简便,结果可靠。土茯苓也为方中主药之一,现代研究表明[2],土茯苓含多种化学成分,有糖类、有机酸类、苯丙素类、黄酮和黄酮苷类、甾醇类、皂苷类及挥发油等,具有解毒利湿、凉血解毒、祛风止痛的功效。其中落新妇苷为其主要化学成分,与土茯苓临床疗效一致,本研究采用HPLC法对制剂中落新妇苷进行含量测定,能保证更有效地对头痛宁胶囊进行质量控制。
