| 摘 要： | 分别用浓度为80%,90%和100%的甲醇提取坛紫菜的天然防晒物质,分析其紫外吸收能力和抗氧化能力.结果表明,采用80%的甲醇对坛紫菜进行提取的效果最好.坛紫菜的MAAs粗提物在紫外波段(ultraviolet radiation,UVR,280～400 nm)具有明显的吸收峰,说明该提取物具有良好的紫外吸收能力.将MAAs粗提物与市购防晒乳霜(自然堂,SPF18)分别按质量比为1∶30,1∶20,1∶10和1∶5的比例混合后,MAAs粗提物可以显著改良市购防晒乳霜的抗紫外能力,其防晒系数(SPF,sun protection factor)分别增大到22,43,87和114.MAAs粗提物对DPPH和羟自由基的清除率分别为12.82%和0.58%.因此,MAAs粗提物可作为功效成分添加剂应用于防晒化妆品中.

| Abstract: | The paper is aimed to check anti-UVR and anti-oxidant ability of natural sun-screen compounds,the main contents is mycosporine-like amino acids(MAAs),which was extracted from Porphyra haitanensis by 80%,90%,100% methanol,respectively.The results showed that 80% methanol was the best concentration for extracting MAAs in Porphyra haitanensis.The extracted compounds had the potent UV shield ability because of obvious absorption peak under UVR waveband(280-400 nm).For analyzing the sun block results,the compoun... |
