TITLE:
摘要: 目的:建立同时测定双参通冠胶囊中脱氢紫堇碱和丹酚酸B含量的方法。方法:采用HPLC-双波长切换法。色谱柱为Waters symmetry C18,以乙腈-0.05%磷酸溶液为流动相进行梯度洗脱,检测波长为286 nm(丹酚酸B)、336 nm(脱氢紫堇碱),流速为1.0 mL/min,柱温为25 ℃,进样量为10 μL。结果:在建立的检测条件下,脱氢紫堇碱和丹酚酸B均能达到基线分离,二者进样量线性范围分别为 0.157~1.259 μg、0.391~3.131 μg(r均为0.999 9);精密度、重复性和稳定性试验(24 h 内)的RSD均小于2.00%(n=6~10);平均加样回收率分别为101.61%、102.85%(RSD分别为3.59%、2.85%,n=6)。结论:建立的 HPLC-双波长切换法可同时测定双参通冠胶囊中脱氢紫堇碱和丹酚酸B含量,且方法操作简便、快速,可用于双参通冠胶囊的质量控制。
ABSTRACT: OBJECTIVE: To develop an method for determining the contents of dehydrocorydine and salvianolic acid B in Shuangshen tongguan capsules simultaneously. METHODS: The HPLC-dual wavelength switching method was used. The determination was performed on Waters symmetry C18 column with mobile phase consisted of acetonitrile-0.05% phosphoric acid solution (gradient elution) at the flow rate of 1.0 mL/min, the detection wavelength was 286 nm (salvianolic acid B) and 336 nm (dehydrocorydine). The column temperature was maintained at 25 ℃, and sample size was 10 μL. RESULTS: Under this condition, dehydrocorydaline and salvianolic acid B could be separated in baseline. The linear range of them were 0.157-1.259 μg and 0.391-3.131 μg (r=0.999 9). RSDs of precision, reproducibility and stability tests (within 24 h) were all lower than 2.00% (n=6-10). The average recovery rates were 101.61% and 102.85% (RSD=3.59% and 2.85%, n=6). CONCLUSIONS: Established HPLC-dual wavelength switching method can be used for simultaneous determination of dehydrocorydine and salvianolic acid B in Shuangshen tongguan capsules. The method is simple and rapid, and can be used for the quality control of Shuangshen tongguan capsule.
