| Abstract: | Use hot pepper as material,and dissolve it in the solution of 2% sodium hydroxide,after this,acidulate it with the solution of 5% H2SO4,extract with n-Hexane and concentrate it,then the crude product(its degree of purity is 82%～84%)of the capsaicin chemical compound is obtained.In the next step,dissolve the crude product in the mixed solution of n-Hexane-Hexyl acetate,then,after recrystallizing it,the crystal of the high-pure capsaicin chemical compound is obtained,it's degree of purity being 92.5%,according to the examination standard of GB10783—1996.The obtaining rate of the high-pure capsaicin chemical compound is 2.2%(relative to the element of hot pepper). |
