TITLE:
摘要: 目的:建立同时测定桑杏口服液中芦丁、橙皮苷、牛蒡苷、甘草苷含量的方法。方法:采用反相高效液相色谱法。色谱柱为Kromasil C18,流动相为乙腈-0.1%磷酸溶液(梯度洗脱),流速为1.0 mL/min,检测波长为 276 、348 nm,柱温为30 ℃,进样量为5 μL。结果:芦丁、橙皮苷、牛蒡苷、甘草苷检测质量浓度线性范围分别为1.068~10.68 μg/mL(r=0.999 3)、9.320~93.20 μg/mL(r=0.999 2)、46.91~469.1 μg/mL(r=0.999 4)、0.511 0~5.110 μg/mL(r=0.999 2);精密度、稳定性、重复性试验的RSD<3%;加样回收率分别为95.10%~101.90%(RSD=2.1%,n=9)、96.75%~101.80%(RSD=1.4%,n=9)、95.69%~100.00%(RSD=1.5%,n=9)、98.22%~104.60%(RSD=2.1%,n=9)。结论:该方法准确、灵敏、重复性好,可用于桑杏口服液中芦丁、橙皮苷、牛蒡苷、甘草苷含量的同时测定。
ABSTRACT: OBJECTIVE: To establish a method for the simultaneous determination of rutin, hesperidin, arctiin, liquiritin and glycyrrhizinate in Sangxing oral liquid. METHODS: RP-HPLC was performed on the column of Kromasil C18 with mobile phase of acetonitrile-0.1% phosphoric acid solution(gradient elution) at a flow rate of 1.0 mL/min, the detection wavelength was 276, 348 nm, column temperature was 30 ℃,and the injection volume was 5 μL. RESULTS: The linear range was 1.068-10.68 μg/mL(r=0.999 3) for rutin, 9.320-93.20 μg/mL(r=0.999 2) for hesperidin, 46.91-469.1 μg/mL(r=0.999 4) for arctiin, 0.511 0-5.110 μg/mL(r=0.999 2) for liquiritin; RSDs of precision, stability and reproducibility tests were less than 3%;recoveries were 95.10%-101.90%(RSD=2.1%,n=9),96.75%-101.80%(RSD=1.4%,n=9),95.69%-100.00%(RSD=1.5%,n=9), 98.22%-104.60%(RSD=2.1%,n=9), respectively. CONCLUSIONS: The method is accurate, sensitive and reproducible, and can be used for the simultaneous determination of rutin, hesperidin, arctiin and liquiritin in Sangxing oral liquid.
