【Abstract】 Capsicine as a material was used in experiment.The capsicine was dissolved in a solution of 1 % sodium hydroxy,and then it was treated in turn with 2 % sulfuric acid acidation,nhexane extraction concentration.A crude capsaicins compound (Purity 82%～84 %) was obtained.The crude capsaicins compound was dissolved in a solution of 1 % sodium hydroxy.A capsaicins compound crystal was obtained wigh ion exchange,alcohol eghyl acetate elution,concentration and crystallization,yield 2.8%(relative capsicine).Detection on the basis of the GB 10783 96 standard,the capsaicins compound purity was 98.5 %.更多还原
