摘要: 采用RP-HPLC法建立了同时测定珠芽蓼中牡荆素、槲皮苷、槲皮素三种黄酮的方法,色谱柱为kromasil C18(250 mm×4.6 mm, 5 μm),以甲醇-水(含0.25%磷酸)为流动相梯度洗脱,流速1 mL/min,检测波长360 nm。结果表明,牡荆素、槲皮苷和槲皮素质量浓度在8~40 μg/mL、5~50 μg/mL和5.33~52 μg/mL范围内与色谱峰面积均呈良好的线形关系,平均回收率分别为100.3%、98.9%和100.4%,日内稳定性偏差分别为0.78%, 0.51%和0.38%,日间稳定性偏差为2.6%, 1.9%和2.1%。该方法简单、准确,可为珠芽蓼的质量控制提供科学依据。

Abstract: To develop a sensitive and specific reversed-phase high performance liquid chromatography (RP-HPLC) method for simultaneous determination of three flavoniods in Polygonum viviparum, the HPLC separation was performed on a Kromasil C18 column (250 mm×4.6 mm, 5 μm) and detected with DAD at 360nm. The gradient elution was carried out with methano-H2O (containing 0.25% phosphoric acid) as the mobile phase at a flow rate of 1 mL/min. The results indicated that the calibration curves for viterxin, quercetin and quercitrin were linear over the ranges of 8-40 μg/mL, 5-50 μg/mL and 5.33-52 μg/mL, their assay recoveries were 100.3%, 98.9% and 100.4%, their intraday repeatability were 0.78%, 0.51% and 0.38%, and interday repeatability were 2.6%, 1.9% and 2.1%, respectively. This method was simple, accurate and sensitive, so it could be used for the quality control of P. viviparum.
