摘  要:目的建立同时测定天麻头风灵胶囊中原儿茶酸、紫丁香苷、绿原酸含量的方法。方法采用HPLC法。色谱柱为Diamonsil C18柱(200mm×4.6mm,5μm),流动相为甲醇-乙腈-0.05%磷酸溶液(体积比20:5:174),流速为1.0mL·min^-1,柱温为35℃,检测波长为281nm。结果原儿茶酸、紫丁香苷、绿原酸质量浓度分别在2.40—24.0mg·L^-1、5.20~52.0mg·L^-1、26.6-266mg·L^-1内与峰面积呈良好的线性关系,r分别为0.9996、0.9997、0.9995,平均回收率分别为101.0%(RSD=0.86%,n=9)、100.3%(RSD=1.9%,n=9)、101.5%(RSD=1.4%,n=9)。结论HPLC法可用于天麻头风灵胶囊的质量控制。Objective To develop a HPLC method for the determination of protocatechuic acid, syringin and chlorogenic acid in Tianma toufengling (traditional Chinese medicines) capsules. Methods The chromatographic separation was achieved on a Diamonsil C18 (200 mm × 4. 6 mm,5 μm)column with a mobile phase of methanol-acetonitrile-0. 05% phosphoric acid solution ( V: V: V = 20 : 5 : 174 ). The flow rate was 1.0 mL· min^-1 and the column temperature was 35℃. Results The calibration curve was linear within the range of 2. 40 - 24.0 mg· L^-1 ( r = 0. 999 6) for protocatechuic acid,5.20 - 52. 0 mg· L^-1 ( r = 0. 999 7 ) for syringin and 26. 6 - 266 mg· L^ -1 ( r = 0. 999 5) for chlorogenic acid, respectively. The recoveries of protocatechuic acid, syringin and chlorogenic acid were 101.0% (RSD = 0. 86 %, n = 9 ), 100. 3 % (RSD = 1.9%, n = 9)and 101.5 % (RSD = 1.4 %, n = 9 ), respectively. Conclusions The method is accurate, sensitive and specific. It can be used for the quality control of Tianma oufengling capsules.
