摘要: | 目的:建立同时测定蟾龙定喘合剂中补骨脂素、异补骨脂素、朝藿定B、朝藿定C和淫羊藿苷含量的方法。方法:采用高效液相色谱法。色谱柱为Welch Materials C18,流动相为乙腈-甲醇(1 ∶ 1,V/V)-水(梯度洗脱),流速为0.9 ml/min,检测波长为246 nm(补骨脂素和异补骨脂素)、270 nm(朝藿定B、朝藿定C和淫羊藿苷),柱温为30 ℃,进样量为20 μl。结果:补骨脂素、异补骨脂素、朝藿定B、朝藿定C和淫羊藿苷的检测质量浓度线性范围分别为8.24~164.80 μg/ml(r=0.999 7)、5.15~103.00 μg/ml(r=0.999 3)、4.06~81.20 μg/ml(r=0.999 6)、5.88~117.60 μg/ml(r=0.999 5)、4.90~98.00 μg/ml(r=0.999 8);定量限分别为0.385、0.179、0.124、0.218、0.348 μg/ml,检测限分别为0.127、0.059、0.041、0.072、0.115 μg/ml;精密度、稳定性、重复性试验的RSD<2.0%;加样回收率分别为97.93%~100.06%(RSD=0.80%,n=6)、96.91%~100.16%(RSD=1.37%,n=6)、96.95%~99.63%(RSD=0.98%,n=6)、96.69%~99.33%(RSD=1.03%,n=6)、96.76%~98.53%(RSD=0.70%,n=6)。结论:该方法操作简便、结果可靠,适用于同时测定蟾龙定喘合剂中补骨脂素、异补骨脂素、朝藿定B、朝藿定C和淫羊藿苷的含量。 |
ABSTRACT: | OBJECTIVE: To establish a method for the simultaneous determination of psoralen, isopsoralen, epimedin B, epimedin C and icariin in Chanlong dingchuan mixture. METHODS: HPLC was performed on the column of Welch Materials C18 with mobile phase of acetonitrile - methanol (1 ∶ 1,V/V)-water (gradient elution) at a flow rate of 0.9 ml/min, the detection wavelength was 246 nm (psoralen, isopsoralen) and 270 nm (epimedin B, epimedin C and icariin), column temperature was 30 ℃, injection volume was 20 μl. RESULTS: The linear range was 8.24-164.80 μg/ml for psoralen (r=0.999 7), 5.15-103.00 μg/ml for isopsoralen (r=0.999 3),4.06-81.20 μg/ml for epimedin B (r=0.999 6), 5.88-117.60 μg/ml for epimedin C(r=0.999 5) and 4.90-98.00 μg/ml for icariin (r=0.999 8); the limits of quantitation were 0.385 μg/ml, 0.179 μg/ml , 0.124 μg/ml, 0.218 μg/ml and 0.348 μg/ml, limits of detection were 0.127 μg/ml, 0.059 μg/ml ,0.041 μg/ml, 0.072 μg/ml and 0.115 μg/ml; RSDs of precision, stability and reproducibility tests were lower than 2.0%; recoveries were 97.93%-100.06% (RSD=0.80%,n=6), 96.91%-100.16% (RSD=1.37%,n=6), 96.95%-99.63% (RSD=0.98%,n=6), 96.69%-99.33% (RSD=1.03%,n=6) and 96.76%-98.53% (RSD=0.70%,n=6), respectively. CONCLUSIONS: The method is simple and reliable, and suitable for the simultaneous determination of psoralen, isopsoralen, epimedin B, epimedin C and icariin in Chanlong dingchuan mixture. |
