摘要: 建立了一种准确、可靠的HPLC/UV法用于测定黄芪四物胶囊中黄芪甲苷的含量。采用Hypersil-ODS (250 mm× 4.6 mm, 5 μm) 色谱柱, 以乙腈–水 (32:68, v/v) 为流动相等度洗脱, 流速1.0 mL/min, 检测波长203 nm, 并以线性范围、精密度、准确度、专属性和耐用性对该方法进行验证。所验证的方法成功用于测定不同批次黄芪四物胶囊中黄芪甲苷含量。结果表明, 本法可用于黄芪四物胶囊及其它相关植物药中黄芪甲苷的含量测定和质量控制。

Abstract:

A reliable and accurate HPLC/UV method was developed for the quantitative determination of astragaloside IV in 'Huang-Qi-Si-Wu' Capsules, a widely used prescription of traditional Chinese medicines (TCM). The chromatographic separation conditions employed for HPLC/UV were optimized using a Hypersil-ODS column (250 mm×4.6 mm, 5.0 μm) with isocratic elution. Acetonitrile–water (32:68, v/v) were used as the mobile phase pumped at a flow rate of 1.0 mL/min and a detection wavelength at 203 nm was used. The method was fully validated with respect to linearity, precision, accuracy, specificity and robustness. The validated method was applied successfully to the quantification of astragaloside IV in the extract of 'Huang-Qi-Si-Wu' Capsules from different production batches. The results indicate that the established HPLC/UV method is suitable for the quantitative analysis and quality control of 'Huang-Qi-Si-Wu' Capsules and other related botanical drugs.
