摘要
采用响应面法优化以水为溶剂同时提取广西甜茶干叶中的甜茶苷和甜茶多酚的工艺。利用Box-Behnken响应面分析法,以甜茶苷提取率和甜茶多酚提取率为响应值,优化了同时提取甜茶苷和甜茶多酚的最佳工艺为:提取温度57℃,液料比为25∶1 mL/g,提取时间为36 min,在此条件下,甜茶多酚提取率为85.32%(RSD=1.42%,n=3),甜茶苷的提取率为83.58%(RSD=2.24%,n=3)。该研究结果为甜茶叶的综合利用提供了实验依据。
Distilled water was used as extraction solvent,response surface methodology was used to optimize the simultaneous extraction process of rubusoside and polyphenols from dried leaves of Guangxi sweet tea.According to the Box-Behnken design method,the extraction rate of rubusoside and sweet tea polyphenols were taken as the response values respectively,the best process of simultaneous extracting rubusoside and sweet tea polyphenols was: The extraction temperature was 57 ℃,the ratio of liquid to material was 25∶ 1 mL/g,the extraction time was 36 min,and the extraction rate of sweet tea polyphenols was 85.32%(RSD = 1.42%,n = 3),the extraction rate of rubusoside was 83.58%(RSD = 2.24%,n = 3). The results provided an experimental basis for the comprehensive utilization of sweet tea.
