摘 要 辣椒素俗名辣素（又称辣椒碱类化合物），是辣椒中引起辛辣味的物质。辣椒素的化学组成主要为辣椒碱，是辣椒素中含量最高的成分，占辣椒素类物质的60%-70%,另一种成分二氢辣椒碱一般占20%-30%。天然辣椒素主要从辣椒中提取，其具有多种药理生理学活性，且纯天然、低毒害、无污染，应用范围较广。如在医药方面上用于生产镇痛药，戒毒药，在食品工业中作为辣味剂，饲料工业中作为添加剂，在军事上用于生产催泪武器等。辣椒素的应用具有较好的发展前景，因而对辣椒素的提取研究将会有强大的市场发展潜力。 本论文进行了酸性溶剂法对辣椒素提取工艺的研究，考察了不同提取液浓度，提取时间，提取温度及料液比四个因素对辣椒素提取率的影响，通过正交实验设计，选出辣椒素的最佳提取工艺为：提取溶剂为HCl、提取时间4h、物料比为1∶12、提取液浓度为6％（W/V）、提取温度为30℃,提取得率达到0.10346%。对辣椒素进行了定性、定量分析,并进一步探讨辣椒素的药理生理意义。 关键词：辣椒素；酸性溶剂法；提取工艺 Abstract Capsaicin ghost spicy meat (also called capsaicin hydrocarbons), is caused in chili piquancy substances. The chemical composition of capsaicinoids is mainly for capsaicin, the highest content of capsaicin, accounted for capsaicin ingredients 60% ~ 70% of substance, another component dihydrogen capsaicin general 20% ~ 30%. Natural capsaicin extract, mainly from chili has many pharmacological physiology activity the natural, low, and the harm, no pollution, application scope is more extensive. As in the medicine for the production of analgesic drugs, rehabilitation medicine and in the food industry as spicy agent, feed industry as additives, militarily used in the production of tear weapons, etc. Capsaicin applications have good growth prospects, and the extraction of capsaicin research will have strong market potential. This paper made acidic solvent method to capsaicin extraction process study on different extract concentration, extraction time, material liquid extraction temperature and than four factors on the influence of capsaicin, extraction through orthogonal experiment design, select the best extraction technology of capsaicin ，extraction solvent for：HCl，extracting time for: 4 h, material liquid ratio for：1:12，extract concentration for：6％（W/V） ， extraction temperature for: 30 ℃,To get rate of 0.10346%.To capsaicin conduct qualitative and quantitative analysis, and further discusses the pharmacological significance of capsaicin. Keywords: capsaicin; Acidic solvent method; extraction technology 目 录 摘 要 I Abstrac
