摘要: 建立玛咖中芥子油苷成分的高效液相检测方法。采用80%甲醇溶液萃取、过DEAE-Sephadex A-25交换柱及硫酸酯酶酶解处理获得玛咖中芥子油苷样品,以苄基芥子油苷为外标对照品,C18色谱柱,流动相A为0.05%四甲基氯化铵水溶液,流动相B为0.05%四甲基氯化铵、20%乙腈的水溶液,梯度洗脱,检测波长229 nm,对玛咖芥子油苷含量进行检测。结果表明,玛咖芥子油苷的标准曲线在0.0179~0.2684 mg/mL浓度范围内呈现良好的线性关系(R2=0.9999),精密度相对标准偏差为0.052%,不同浓度加标回收率为89.2%~93.0%,最低检测线可达到1 μg/kg。实验证实:该方法简单、稳定、灵敏度高,可作为玛咖芥子油苷的常规检测方法。

Abstract: This study aimed to establish one smiple and fast analytical method for detecting glucosinolate in Maca by high performance liquid chromatography(HPLC).Maca powder was extracted with 80% methanol,then the extractions were absorbed onto a column packed with DEAE-Sephadex A-25,followed by enzymatic hydrolysis with sulfatase,after this step we obtained the sample to be tested.The chromatographic method was carried out on a C18 column using the 0.05% Tetramethylammonium chloride aqueous solution as the mobile phase A and 0.05% Tetramethylammonium chloride aqueous solution(containing 20% acetonitrile,V/V) as B,Benzyl glucosinolate as standard reference material.The flow rate was 1 mL/min on the gradient elution.The monitoring wavelength was at 229 nm.Results showed that linear ranges of glucosinolate was between 0.01790.2684 mg/mL(R2=0.9999).The RSD of precision was 0.052%.The sample recovery rate in different concentrations was 89.2%-93.0%.The detection limit can reach 1 μg/kg.This method is reliable and could be used as a quality control method for glucosinolates.
