摘要:

采用高速逆流色谱法(HSCCC)分离纯化红曲发酵产品中6 种Azaphilone 类色素组分。筛选弱极性分离溶剂系统正己烷- 醋酸乙酯- 甲醇- 水,研究6 种色素组分在不同溶剂体系中的分配系数,建立两步逆流萃取分离的技术路线。经过HPCCC 分离纯化和丙酮结晶操作,得到6 种高纯度的Azaphilone 类色素组分,纯度均大于98.5%,得率达到81.40%~84.78%,所得的6 种色素组分的摩尔吸光系数分别为13313、13877、9380、9360、25621、25849L/(mol·cm)。本研究可提供一种新型的制备高纯度红曲Azaphilone 类色素组分的技术路线。

Abstract:

Six azaphilone-type pigments were separated from Monascus-fermented solid medium and purified/fractionated by by high-speed counter-current chromatography (HSCCC). A solvent system with weak polarity involving four components nhexane, ethyl acetate, methanol and water was selected and used for HSCCC. Based on a comparative analysis of partition coefficients of target compounds in different solvent systems, a two-step HSCCC routine was developed. After separation by HSCCC and crystallization with acetone, six azaphilone-type pigments with high purity were obtained. The purity of each pigment was above 98.5% and their yields were between 81.40% and 84.78%. Their molar absorption coefficients were 13313, 13877, 9380, 9360, 25621 L/(mol·cm) and 25849 L/(mol·cm), separately.

Key words: Monascus pigments, high-speed counter-current chromatography, separation and purification
