摘要
通过滤纸片法就辣椒碱单体、二氢辣椒碱单体、降二氢辣椒碱单体及辣椒素对细菌和真菌的抑制效果进行了考察,结果表明:辣椒碱单体具有明显的抑菌作用,抑菌效果明显好于二氢辣椒碱单体、降二氢辣椒碱单体和辣椒素。进一步比较发现,辣椒碱单体对5种菌株抑菌效果由大到小依次为金黄色葡萄球菌>大肠杆菌>铜绿假单胞菌>白色念珠菌>黑曲霉菌。因此,以辣椒碱单体为主要原料开发天然高效的抑菌防腐剂具有实际意义。
The inhibitory effects of capsaicin monomer, dihydrocapsaicin monomer and capsaicinoids on five strains of bacteria and fungi have been studied by the filter paper diffusion method. The results showed that the antibacterial effects of capsaicin monomer were superior to those of dihydrocapsaicin monomer, and capsaicinoids. Furthermore, the antibacterial effects of capsaicin monomer on the five strains decreased in the order: Staphylococcus aureus > Escherichia coli > Pseudomonas aeruginosa > Monilia albican > Aspergillus niger. This work provides a technical reference and basic data to support the future application of capsaicin as a natural antibacterial preservative.
