摘要: 辣椒碱(CAP)是一种从辣椒中分离出来的生物碱,作为香料被广泛使用。已有研究结果表明,辣椒碱具有多效性,如抗炎、抗氧化和抗癌症等作用,但其影响动物肠道功能和肠道菌群组成方面的研究相对较少。本文综述了辣椒碱对动物肠道功能和肠道菌群的调节作用,并阐述其在缓解动物肠炎发生和发展方面的作用机制,为辣椒碱在维持肠道稳态方面的应用提供理论基础。

Abstract: Capsaicin is an alkaloid isolated from peppers and is widely used as spice. Previous studies have shown that capsaicin has pleiotropic effects, such as anti-inflammatory, antioxidant and anticancer effects, but less attention has been paid to its effects on animal intestinal function and intestinal microflora composition. In this paper, the regulatory effect of capsaicin on animal intestinal function and intestinal microflora was reviewed, and its action mechanism in relieving the occurrence and development of animal intestinal inflammation was described, so as to provide a theoretical basis for the application of capsaicin in maintaining intestinal homeostasis.
Key words: capsaicin;intestinal function;intestinal microflora;intestinal homeostasis;intestinal inflammation
辣椒碱(CAP)是一种从辣椒中分离出来的生物碱,其化学名称为8-甲基-N-香草基-6-壬烯酰胺。近年来已有较多研究结果证明CAP具有多方面的益处,如抗炎、抗氧化和抗菌等功效[1-4],但关于其对肠道功能和肠道菌群方面影响的研究相对较少。已有研究结果表明,CAP对肠道功能和菌群具有有益的作用,可抑制肠道致病菌,促进有益菌的生长[5-7]。因此,本研究将CAP与肠道功能和肠道菌群的组成、丰度联系起来进行探讨,旨在对这些效应进行系统化的综述并揭示CAP发挥作用的潜在机制。
1 CAP对胃肠道系统的有益作用
1.1 CAP调节肠道形态结构的作用
Filik等[8]的研究结果表明,随着饲料的中辣椒渣(HPWP,CAP是其主要成分)的添加量增加,鹌鹑的肠绒毛高度、黏膜下层、浆膜、肌层、绒毛高度/隐窝深度和绒毛表面积也随之显著增加,肠道的杯状细胞数量也增加,提高了鹌鹑的生产性能。Liu等[9]将大肠杆菌F18攻毒的断奶仔猪模型与对照组相比发现,添加CAP 能够提高仔猪肠道黏膜和黏蛋白2的mRNA表达量。……
