How to separate Safflower Pigment?
red pigment separation method
The safflower red pigment obtained by alkali extraction is subjected to acid precipitation. After dissolution, adsorption was performed using a microcrystalline cellulose column followed by acetone. Methanol=8:2 solution elution, at this time the purity of red pigment reaches 91%. For further purification, Sephadex LH-20 column chromatography is used, the eluent is water, 60% acetone, and the purity of red pigment can reach 96%.
yellow pigment separation method
The yellow pigment solution was first subjected to XAD-2000 column chromatography. The eluent is 1% acetic acid in different concentrations of ethanol aqueous solution, which can obtain solutions with different mixed components. After further preparative HPLC, eluent A 10% aqueous acetic acid.
The main application of Safflower Pigment：
Medical efficacy
Cardiovascular System
(1) The experiment of dilating coronary artery and improving myocardial blood supply showed that safflower yellow can slightly excite the heart, reduce coronary resistance, and increase coronary flow and myocardial nutritional blood flow.
(2) Lower blood pressure, dilate blood vessels and improve blood supply to organs.
Blood system
(1) Inhibitory effect on platelet aggregation;
(2) Prolongation of prothrombin time;
(3) Prolongation of partial thromboplastin time.
Tolerance
Safflower yellow has significant hypoxia tolerance and fatigue effects.
Analgesic effect
Safflower yellow has a strong and long-lasting analgesic effect.
Food coloring
China's safflower resources are widely distributed and the output is relatively large. Its extract, safflower yellow pigment, is also a natural and safe food coloring and has great potential for development in export food colorings or additives, textiles, and medicine. Safflower yellow has been successfully used in the coloring of various beverages, alcohol, and healthy food. Since synthetic tartrazine is a toxic pigment, it has been banned in many countries, and safflower yellow can be used as the preferred pigment for infant and elderly health care food.
