TITLE: | |
摘要: | 目的:建立同时测定复方鱼腥草片中绿原酸、黄芩苷和槲皮素含量的方法。方法:采用高效液相色谱法。色谱柱为GL InterSustain-C18,流动相为水-甲醇(55 ∶ 45,V/V),流速为1.0 mL/min,检测波长为270 nm,柱温为30 ℃,进样量为20 μL。结果:绿原酸、黄芩苷和槲皮素的检测质量浓度线性范围分别为1.264~12.64 μg/mL(r=0.999 9)、8.704~87.04 μg/mL(r=0.999 9)、1.212~12.12 μg/mL(r=0.999 9);定量限分别为1.88、2.98、1.94 ng,检测限分别为0.56、0.89、0.58 ng;精密度、稳定性、重复性试验的RSD<2.0%;加样回收率分别为98.02%~101.10%(RSD=1.01%,n=9)、97.48%~101.70%(RSD=1.38%,n=9)、98.31%~101.10%(RSD=1.02%,n=9)。结论:该方法操作简便,精密度、稳定性、重复性好,可用于复方鱼腥草片中绿原酸、黄芩苷和槲皮素含量的同时测定。 |
ABSTRACT: | OBJECTIVE: To establish a method for simultaneous determination of chlorogenic acid, baicalin and quercetin in Compound yuxingcao tablets. METHODS: HPLC method was adopted. The separation was performed on GL InterSustain-C18 column with mobile phase consisted of water-methanol (55 ∶ 45,V/V) at the flow rate of 1.0 mL/min. The detection wavelength was set at 270 nm, and the column temperature was 30 ℃. The sample size was 20 μL. RESULTS: Linear ranges of chlorogenic acid, baicalin and quercetin were 1.264-12.64 μg/mL (r=0.999 9), 8.704-87.04 μg/mL(r=0.999 9) and 1.212-12.12 μg/mL(r=0.999 9), respectively. The limit of quantification were 1.88, 2.98, 1.94 ng, respectively. The limits of detection were 0.56, 0.89, 0.58 ng, respectively. RSDs of precision, stability and reproducibility tests were all lower than 2.0%. The recoveries were 98.02%-101.10% (RSD=1.01%,n=9), 97.48%-101.70%(RSD=1.38%,n=9) and 98.31%-101.10%(RSD=1.02%,n=9), respectively. CONCLUSIONS: The established method is simple, accurate, stable and reproducible, and can be used for simultaneous determination of chlorogenic acid, baicalin and quercetin in Compound yuxingcao tablets. |
