摘要
为评价三种替代冬虫夏草发酵菌粉的应用价值,对虫草头孢菌粉、蝙蝠蛾拟青霉菌粉及虫草被孢菌粉的主要活性成分和营养成分进行了比较分析.结果表明:蝙蝠蛾拟青霉菌粉总蛋白和粗纤维含量最高,虫草被孢菌粉碳水化合物含量最高;虫草头孢菌粉胞苷含量最高,3个发酵菌粉中均未检出虫草素和肌苷;虫草被孢菌粉多糖中葡萄糖含量明显低于其他菌粉,虫草头孢菌粉多糖分子量最高,虫草被孢菌粉和蝙蝠蛾拟青霉菌粉多糖的分子量差异不大.与文献报道的天然冬虫夏草的活性成分和营养成分进行比较,发现三种替代冬虫夏草发酵菌粉在腺苷、胞苷含量上均高于天然冬虫夏草.这些结果揭示三种替代冬虫夏草发酵菌粉在功效上有差异,并且三种菌粉在某些功效上要高于天然冬虫夏草.
In this paper,we investigated the main bioactive composition and nutritional components of the three fermented power from Cephalosporium sinensis,Mortierella hepialid,Paecilomyces hepiali Cs-4.The fermented power from Paecilomyces hepiali Cs-4 had the highest total protein and crude fiber contents and the lowest carbohydrate content,while the fermented power from Cephalosporium sinensis had the highest carbohydrate content and the lowest total protein and crude fiber contents.Cytidine content in the fermented power from Cephalosporium sinensis(9.88 mg/g)was the highest,while cytidine content in the fermented power from Mortierella hepialid(4.32 mg/g)was the lowest.Cordyceps and inosine in three fermented samples were not detected.Lactose content in the crude polysaccharide of fermented power from Mortierella hepialid was significantly lower than other two fermented power.The molecular weight of fermented power from Cephalosporium sinensis is significantly higher than other fermented power.There was not obvious difference in the molecular weight between fermented power of Mortierella hepialid and fermented power of Paecilomyces hepialid.
