目的:建立同时测定热感赛比斯坦颗粒中没食子酸、迷迭香酸、甘草苷和甘草酸铵含量的方法。方法:采用反相高效液相色谱法。色谱柱为Waters RP-C18,流动相为乙腈-0.2%磷酸溶液(梯度洗脱),流速为1.0 mL/min,检测波长为210 nm(没食子酸、迷迭香酸和甘草苷)、230 nm(甘草酸铵),柱温为28℃,进样量为20 μL。结果:没食子酸、迷迭香酸、甘草苷和甘草酸铵检测进样量线性范围分别为0.274 4~7.546 μg(r=0.999 8)、0.187 0~5.143 μg(r=0.999 6)、0.130 0~3.575 μg(r=0.999 9)、0.254 0~6.985 μg(r=0.999 8);定量限分别为2.67、1.36、1.09、2.11 ng,检测限分别为1.03、0.62、0.87、0.91 ng;精密度、稳定性、重复性试验的RSD<2.0%;加样回收率分别为97.26%~101.00%(RSD=1.1%,n=9)、97.66%~101.80%(RSD=1.3%,n=9)、97.45%~101.70%(RSD=1.4%,n=9)、97.74%~101.70%(RSD=1.4%,n=9)。结论:该方法简便、准确,重复性好,可用于热感赛比斯坦颗粒中没食子酸、迷迭香酸、甘草苷和甘草酸铵含量的同时测定。

ABSTRACTOBJECTIVE:To establish the method for simultaneous determination of gallic acid,rosmarinic acid,liquiritin and ammonium glycyrrhetate in Regan saibisitan granules.METHODS:RP-HPLC method was adopted.The determination was performed on Waters RP-C18column with mobile phase consisted of acetonitrile-0.2%phosphoric acid(gradient elution)at the flow rate of 1.0 mL/min.The detection wavelengths were 210 nm(gallic acid,rosmarinic acid and liquiritin),230 nm(ammonium glycyrrhetate).The column temperature was 28℃,and sample size was 20 μL.RESULTS:The linear ranges were 0.274 4-7.546 μg for gallic acid(r=0.999 8),0.187 0-5.143 μg for rosmarinic acid(r=0.999 6),0.130 0-3.575 μg for liquiritin(r=0.999 9)and 0.254 0-6.985 μg for ammonium glycyrrhetate(r=0.999 8),respectively.The LOQ were 2.67,1.36,1.09 and 2.11 ng,respectively.The LOD were 1.03,0.62,0.87 and 0.91 ng,respectively.RSDs of precision,stability and repeatability tests were all less than 2.0%.The average recoveries were 97.26%-101.00%(RSD=1.1%,n=9),97.66%-101.80%(RSD=1.3%,n=9),97.45%-101.70%(RSD=1.4%,n=9),97.74%-101.70%(RSD=1.4%,n=9).CONCLUSIONS:The method is simple,accurate and reproducible,and can be applied for simultaneous determination of gallic acid,rosmarinic acid,liquiritin and ammonium glycyrrhetate in Regan saibisitan granules.
