| 摘 要： | 将无溶剂微波预处理与NaOH搅拌提取相结合提取辣椒素类物质(Capsaicinoids)。在干辣椒样品中加入微波吸收介质羰基铁粉(CIP),对干辣椒样品进行微波预处理。根据辣椒素与NaOH之间可发生特异性反应,利用NaOH溶液从辣椒中提取两种主要的辣椒素类化合物---辣椒素(Capsaicin,C)和二氢辣椒素(Dihydrocapsaicin,DHC)。实验表明,本方法提取时间短(10min),提取率高,并可有效避免有机溶剂对实验室的污染。

| Abstract: | Solvent-free microwave pretreatment ( SFMP) coupled with sodium hydroxide aqueous solution stir extraction was applied to the extraction of capsaicinoids. In the microwave pretreatment,Carbonyl iron powders ( CIP) was added into the samples,which was used as microwave absorption medium. Then,based on the reaction with capsaicinoids,NaOH aqueous solution was used to extract the capsaicin and dihydrocapsaicin. The experimental results demonstrated that the proposed method shortened the extraction time, increa... |
