摘要:

利用亚临界水萃取丹参药材中的丹参红色素。以丹参酮Ⅱ -A 的提取率作为丹参红色素提取率的考察指标,通过单因素试验研究在丹参红色素的亚临界水萃取过程中萃取温度、萃取时间、物料粒径、液固比、提取剂乙醇体积分数因素对丹参红色素提取率的影响。在单因素试验结果的基础上,选择萃取温度、萃取时间、物料粒径、液固比4 个因素进行正交试验,确定丹参红色素的最佳亚临界水萃取工艺。结果表明:4 个因素对丹参红色素提取率影响的主次顺序为温度>物料粒径>料液比>时间;最优组合为A3B1C1D3,即萃取温度200℃、物料粒径40~60目、液固比25:1(mL/g)、萃取时间10min。在此最优组合基础之上,选择体积分数15% 乙醇溶液作为萃取溶进行萃取,此时所得色素提取率最高为0.319%。

Abstract:

Red pigment was extracted from Salvia miltiorrhiza using subcritical water. The major factors including extraction temperature, extraction time, particle size, liquid-material ratio and ethanol concentration played an important role in subcritical water extraction processing. The effects of above factors on extraction rate of red pigment were investigated. Moreover, the optimal extraction conditions of red pigment were explored by orthogonal experiments to be extraction temperature of 200 ℃, particle size of 40-60 meshes, liquid-material ratio of 25:1, extraction time of 10 min and ethanol concentration of 15%. The extraction rate of red pigment from Salvia miltiorrhiza was 0.319% under the optimal extraction conditions.

Key words: Salvia miltiorrhiza, subcritical water, tanshinone II-A, red pigment, extraction rate
