| 中文摘要: |
| 对巴西粒毛盘菌黑色素性质和结构进行了研究，结果表明该黑色素易溶于NaOH溶液和二甲亚砜，微溶于蒸馏水，不溶于甲醇、乙酸乙酯、HCl、无水乙醇、氯仿、丙酮、乙腈；该黑色素在pH≥7时稳定，pH≤6时产生沉淀；对温度、光、UV、Na2SO3、苯甲酸钠、柠檬酸、蔗糖、K+、Na+、Ca2+、Al3+、Cu2+均具有良好的稳定性，而对H2O2、Mg2+、Fe3+、Mn2+不稳定。电镜扫描显示该黑色素是一种表面不规则的片状晶体，红外光谱分析表明该黑色素含有芳环、-OH、-NH、-COOH和噻嗪环等官能团，推断其属于真黑色素和棕黑色素混合型黑色素。 |
| 英文摘要: |
| The melanin produced by Lachnum brasiliense 84-2 is soluble in NaOH solution and dimethylsulfoxide, slightly soluble in water, and not in methanol, ethyl acetate, HCl, anhydrous ethanol, chloroform, acetone and acetonitrile. The melanin is stable in pH≥7, but deposit in pH≤6 The melanin shows stable to temperature, sunlight, ultraviolet light, sodium benzoate, citric acid, sucrose, K+, Na+, Ca2+, Al3+, Cu2+and Na2SO3 but unstable to Mg2+, Fe3+, Mn2+and H2O2. Scanning electron microscopy indicates that the melanin is a kind of sheet crystalloid whose surface is anomalistic. Infrared spectrum analysis shows that it has functional groups of aryl, -OH, -NH, -COOH and thiazinyl. It is concluded that the melanin has the structure model of both eumelanin and pheomelanin. |
