Abstract

The invention provides a method for efficiently separating crocetin from fruits of rubiaceous plants and gardenia (stenophyllous gardenia, spoonleaf gardenia, gardenia hainanensis, gardenia sootepensis and gardenia) plants, saffron and saffron tissue cultures. The crocetin can be prepared by the method, and meanwhile, the gardenia yellow pigment and the saffron pigment can be prepared. The method comprises the following steps: extracting the pigment of gardenia fruits (the saffron and the saffron tissue cultures) through acid water or directly extracting raw materials through alkaline water, then carrying out water liquid acidification, then extracting ethyl acetate to obtain a crocetin crude product, and recrystallizing the crude product through different solvents to obtain a crocetin pure product. The crocetin, the gardenia yellow pigment and the saffron pigment provided by the invention can be applied in preparing cardiovascular and cerebrovascular disease medicaments, gynecological disease medicaments, tumor adjuvant therapy medicaments and foods. The method of the invention has reasonable design, the crocetin, the gardenia yellow pigment and the saffron pigment can be obtained in large scales and have high yield, and the method is quite suitable for industrialized production.
