【摘要】 采用溶剂浮选分离富集-HPLC测定了茵陈水煎液中的滨蒿内酯。考察了浮选溶剂、N2气流速、试液pH值、浮选时间及电解质NaCl等因素对浮选效果的影响,确定了最佳浮选条件。在最佳条件下加标回收率为92.31%～99.97%,RSD=3.20%,可满足实际样品的分析。更多还原

【Abstract】 Scoparone was separated and concentrated from artemisia capillaris thunb by solvent sublation and determined with high-performance liquid chromatography(HPLC).The experimental conditions such as solution pH,type of solvent,nitrogen flow rate and sublation time were optimized for efficient sublation.The recoveries ranged from 92.31% to 99.97% under the optimal conditions;the RSD value for 5 replicate measurements of the sample was 3.20%.更多还原
