摘要: | 目的:建立同时测定复方穿心莲片中穿心莲内酯、槲皮素-3-O-葡萄糖苷、脱水穿心莲内酯、山柰酚-3-O-葡萄糖苷含量的方法。方法:采用高效液相色谱法。色谱柱为Phenomenex C18,流动相为乙腈-0.1%磷酸(梯度洗脱),流速为1.0 ml/min,检测波长为225 nm(穿心莲内酯)、335 nm(槲皮素-3-O-葡萄糖苷)、254 nm(脱水穿心莲内酯和山柰酚-3-O-葡萄糖苷),柱温为25 ℃,进样量为10 μl。结果:穿心莲内酯、槲皮素-3-O-葡萄糖苷、脱水穿心莲内酯和山柰酚-3-O-葡萄糖苷的检测进样量线性范围分别为0.111~2.770、0.064~1.605、0.086~2.138、0.050~1.260 μg (r均为0.999 9);定量限分别为0.48、0.88、0.93、1.03 ng,检测限分别为0.79、1.15、0.96、1.07 ng;精密度、稳定性、重复性试验的RSD<2.0%;加样回收率分别为96.57%~100.30%(RSD=1.3%,n=9)、95.04%~98.87%(RSD=1.3%,n=9)、95.74%~102.92%(RSD=2.4%,n=9)、96.73%~100.95%(RSD=1.6%,n=9)。结论:该方法简单灵敏、准确可靠、重复性好,可用于同时测定复方穿心莲片中穿心莲内酯、槲皮素-3-O-葡萄糖苷、脱水穿心莲内酯、山柰酚-3-O-葡萄糖苷的含量。 |
ABSTRACT: | OBJECTIVE: To establish a method for the simultaneous determination of andrographolide, quercetin-3-O-glucoside, dehydroandrographolide and kaempferol-3-O-glucoside in Compound chuanxinlian tablet. METHODS: HPLC was performed on the column of Phenomenex C18 with mobile phase of acetonitrile - 0.1% phosphoric acid aqueous(gradient elution) at a flow rate of 1.0 ml/min, the detection wavelength was 225 nm for andrographolide, 335 nm for quercetin-3-O-glucoside and 254 nm for dehydroandrographolide and kaempferol-3-O-glucoside, column temperature was 25 ℃, and the volume injection was 10 μl. RESULTS: The linear range was 0.111-2.770 μg for andrographolide(r=0.999 9),0.064-1.605 μg for quercetin-3-O-glucoside (r=0.999 9), 0.086-2.138 μg for dehydroandrographolide(r=0.999 9) and 0.050-1.260 μg for kaempferol-3-O-glucoside(r=0.999 9); the limits of quantitation were 0.48 ng, 0.88 ng,0.93 ng and 1.03 ng, the limits of detection were 0.79 ng, 1.15 ng,0.96 ng and 1.07 ng,respectively;RSDs of precision, stability and reproducibility tests were lower than 2.0%;recoveries were 96.57%-100.30%(RSD=1.3%,n=9),95.04%-98.87% (RSD=1.3%,n=9), 95.74%-102.92% (RSD=2.4%,n=9) and 96.73%-100.95%(RSD=1.6%,n=9),respectively. CONCLUSIONS: The method is sensitive, reliable and reproducible, and can be used for the simultaneous determination of andrographolide, quercetin-3-O-glucoside, dehydroandrographolide and kaempferol-3-O-glucoside in Compound chuanxinlian tablet. |
