Plectania YM421胞内黑色素提取及其生物功能

Extraction Technology of Intracellular Melanin and Its Biological Function from Plectania YM421

对暗盘菌YM421菌株胞内黑色素的提取工艺、抗紫外线活性、抗卵磷脂氧化和抗油脂氧化进行了研究。结果表明PlectaniaYM421胞内黑色素最佳提取条件是A3B3C2,即提取时间为4 h,提取温度为90℃,料液质量比为1∶200;该黑色素具有较强的抗紫外线能力,在质量浓度为80 mg/mL时对卵磷脂抗氧化指数为56%,能显著抑制大豆油的氧化。

In this manuscript, the extraction process of melanin from Plectania YM421, and the abilities of anti-ultraviolet ray irradiation, antioxidative on phosphatidylcholine and bean oil of the melanin were studied. The optimal process parameters for melanin extraction from Plectania YM421 was achieved： extraction times as 4 hours, extraction tempretrue as 90℃ and ratio of material to solution as 1 ： 200. The melanin exhibits the strong ability of anti-ultraviolet ray irradiation, and the oxygen radical absorbance capacity of phosphatidylcholine was 56% at 80mg/ mL of the melanin. Furthermore, the melanin can highly inhibit oxidative activity of bean oil.
