TITLE: | |
摘要: | 目的:建立同时测定感冒清片中穿心莲内酯和脱水穿心莲内酯含量的方法。方法:采用高效液相色谱法。色谱柱为Thermo BDS C18,流动相为甲醇-水(梯度洗脱),流速为1.0 ml/min,检测波长为 225 nm(穿心莲内酯) 、254 nm(脱水穿心莲内酯),柱温为30 ℃,进样量为10 μl。结果:穿心莲内酯和脱水穿心莲内酯的检测质量浓度线性范围分别为2.25~45.00、1.00~20.00 μg/ml(r=0.999 9);精密度、稳定性、重复性试验的RSD≤0.8%;加样回收率分别为96.96%~99.80%、96.79%~100.65%,RSD分别为1.0%、1.5%(n=9)。结论: 该方法简便、准确、可靠,可用于感冒清片中穿心莲内酯和脱水穿心莲内酯的含量测定。 |
ABSTRACT: | OBJECTIVE:To establish a method for simultaneous determination of andrographlide and dehydroandrographolide in Ganmaoqing tablet. METHODS: HPLC was performed on the column of Thermo BDS C18 with mobile phase of mathanol-water at a flow rate of 1.0 ml/min, detection wavelength was 225 nm for andrographlide and 254 nm for dehydroandrographolide, column temperature was 30 ℃, and injection volume was 10 μl. RESULTS:The linear range was 2.25-45.00 μg/ml for andrographlide(r=0.999 8) and 1.00-20.00 μg/ml for dehydroandrographolid(r=0.999 0); RSDs of precision, stability and reproducibility tests were no more than 0.8%; average recoveries were 96.96%-99.80%(n=9) and 96.79%-100.65%(n=9). CONCLUSIONS:The method is simple, accurate and reliable, and can be used for the quality control of andrographlide and dehydroandrographolide in Ganmaoqing tablet. |
