摘要
目的:优选党参的亚临界水提取工艺。方法:以党参炔苷和党参多糖提取率的综合评分为指标,采用单因素试验和正交试验考察料液比、提取时间和温度对党参亚临界水提取工艺的影响,并与传统提取工艺进行比较。结果:最佳亚临界水提取工艺为提取温度150℃,提取时间45 min,料液比12 mL.g-1;党参炔苷和党参多糖的提取率分别达0.110 2,195.1mg.g-1。结论:与传统水煎煮工艺相比,优选的工艺可明显降低提取时间,并显著提高党参炔苷和党参多糖的提取率。
Objective： To optimize subcritical water extraction technology of Codonopsis tangshen. Method： With composite score of yield of lobetyolin and polysaccharides from C. tangshen as index,effects of liquid-solid ratio,extraction time and temperature on subcritical water extraction technology was investigated by single-factor tests and orthogonal test,and compared with traditional extraction technology. Result： Optimum extraction conditions were obtained as follows：extraction temperature 150 ℃,liquid-solid ratio 12 mLg-1,extraction time 45 min;Under these conditions,yield of lobetyolin and polysaccharides from C. tangshen was up to 0.110 2,195.1 mgg-1, respectively. Conclusion： Comparing with conventional water boiling technology,this optimized technology could significantly shorten extraction time and significantly improve yield of lobetyolin and polysaccharides from C. tangshen.
