摘　　要：以坛紫菜(Porphyra haitanensis)为原料,提取抗紫外辐射物质类菌胞素氨基酸(Mycosporine-like amino acids,MAAs),通过紫外可见光谱、液质联用对其进行表征,研究了化妆品体系中的各因素(pH、光照、温度、防腐剂、抗氧化剂、功能性添加剂)对MAAs化合物稳定性的影响。结果表明,坛紫菜中MAAs类化合物的种类为Shionrine和Porphyra-334;MAAs在pH 6的微酸环境中稳定性最高;紫外照射10 h能使溶液的吸光度下降94.4%;48℃高温放置56 d后吸光度下降了28.3%;48℃下添加小分子肽溶液的吸光度提高了82%,添加透明质酸溶液的吸光度提高了18.6%,能显著增强MAAs化合物的稳定性;其他常用防腐剂、抗氧化剂和功能性添加剂对MAAs的稳定性无明显影响。Taking Porphyra haitanensis as raw material,we extracted the mycosporine-like amino acids(MAAs)and charateri-zed them by UV Vis spectroscopy and Liquid Chromatograph-Mass Spectrometer(LC-MS),so as to study the effects of various factors in the cosmetic system(pH,light,temperature,preservatives,antioxidants and functional additives)on the stability of MAAs.The results show that Shionrine and Porphyra-334 were the main MAAs in P.haitanensis.MAAs had the highest stabili-ty in the weak acid environment with pH=6.UV irradiation for 10 h could decrease the absorbance value by 94.4%.After having been placed at 48℃for 56 d,its absorbance value decreased by 28.3%.At 48℃,the addition of small peptide and hyaluronic acid increased the absorbance value of the solution by 82%and 18.6%,respectively,which could improve the stability of MAAs compounds significantly.Other commonly used preservatives,antioxidants and functional additives had no significant effects on the stability of the MAAs.
