摘要: 类菌胞素氨基酸(MAAs)是一类具有强紫外吸收能力的水溶性氨基酸类物质。本文为研究海萝藻中MAAs的吸湿、保湿性能,采用体外环境保湿测试方法对海萝藻MAAs、丙三醇、透明质酸进行吸湿保湿率测定,对添加不同浓度的海萝藻MAAs浓缩液的爽肤水与乳液进行保湿率测试与吸光度测试。结果表明,海萝藻MAAs的总体吸湿与保湿能力比透明质酸强,但略低于丙三醇;保湿时间长,海萝藻MAAs经过72 h的检测仍表现出比丙三醇和透明质酸高的保湿率;皮肤测试证明添加了60%海萝藻MAAs浓缩液的爽肤水具有最优的保湿效果,经过3 h测试,皮肤含水量较空白区域可提高23.29 c.u.,添加了5%~20%的海萝藻MAAs浓缩液的乳液能显著提高乳液的吸光度值,且添加量越大,吸光值越大。

Abstract: Mycosporine-like amino acids (MAAs) is a kind of water soluble amino acid with strong UV absorption ability.In order to study the moistureabsorption,moisture-retention effects of the MAAs from Gloiopeltis furcata, the MAAs from G.furcata, glycerinum and hyaluronic acid were tested in vitro environment to measure their moisture-absorption and moisture-retention properties.The moisture-retention and absorption photometry of skin lotion and skin emulsion contained various concentration of MAAs from G.furcata were also studied.The results indicated that the general moisture-absorption and moisture-retention effects of MAAs from G.furcata were better than hyaluronic acid,but slightly lower than glycerinum.The MAAs from G.furcata showed higher moisture retention efficiency than glycerinum and hyaluronic acid after 72 hours testing,it can retain water for a long time.The human skin testing indicated the skin lotion contained 60% MAAs concentrated solution showed the best moisture-retention efficiency,the skin hydration has been improved 23.29 C.U.Compared to blank control area after testing for 3 hour,the skin emulsion contained 5% to 20% MAAs concentrated solution can significantly improved their absorbance value,the higher addition of MAAs concentrated solution,the higher absorbance value of skin emulsion.
