摘要
以辣素为原料 ,将其溶于 2 %的氢氧化钠溶液中 ,以 5 %的H2 SO4溶液酸化 ,正己烷萃取并浓缩得纯度为 82 %以上的辣椒碱类化合物粗品 .将粗品辣椒碱类化合物溶解于正己烷 -乙酸已酯混合溶剂中 ,重结晶得纯度为 92 .5 %的高纯辣椒碱类化合物晶体 ,平均得率 2 .2 4 % (相对于辣素 )
Use hot pepper as material,and dissolve it in the solution of 2% sodium hydroxide,after this,acidulate it with the solution of 5% H 2SO 4,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).
