| 摘 要： | 研究姜黄素类化合物的光稳定性,并采用高效液相色谱法对光照前后的姜黄素类化合物溶液进行分析.结果表明:室外光照下,姜黄素的乙醇溶液极不稳定,加入柠檬酸、BHT和β-CD不能显著增强其稳定性,姜黄素固体粉末则较为稳定;室内光照、紫外光照和避光条件下姜黄素溶液均较为稳定.高效液相色谱分析显示:室外光照5 d后,姜黄素、单脱甲氧基姜黄素、双脱甲氧基姜黄素的降解率分别为68.9%、51.5%和21.5%;姜黄素类化合物的主要分解产物为阿魏酸和香草醛.

| Abstract: | The photo-stability of curcuminoid was studied,and its solutions were analyzed pre and post light by HPLC.The results showed that curcuminoid in ethanol solution was unstable exposured to sunlight and stable under the conditions of indoor lighting,UV irradiation and dark;Citric acid,BHT and β-CD were less helpful for the stability of curcuminoid;curcuminoid powder was relatively stable.The analysis of HPLC showed that the degradation rates of curcumin,demethoxycurcumin and bisdemethoxycurcumin were 68.9%,51.5% and 21.5%,respectively,after exposure to sunlight for 5 days.And the major degradation products were ferulic acid and vanillin. |
