秦巴山区野生与栽培猪苓菌核主要成分的测定

Determination of Main Components of Sclerotia in Wild and Cultivated Polyporus umbellatus in Mt. Qinling and Mt.Bashan Regions

摘要:

采用原子吸收分光光度法、高效液相色谱等方法对秦巴山区野生与栽培猪苓菌核的氨基酸、水分、灰分、粗蛋白、粗脂肪、粗纤维、矿质元素、猪苓多糖等主要成分及含量进行测定.结果表明,野生和栽培猪苓在所测定的17种氨基酸中,7种必需氨基酸占氨基酸总量的质量分数分别为33.8%,23.6%.每100g野生与栽培猪苓菌核中水分质量分别为13.22g,11.94g;灰分质量分别为2.86g,2.61g;粗蛋白质量分别为6.87g,4.91g;粗纤维质量分别为27.62g,26.02g;粗脂肪质量分别为1.87g,1.71g;每100g野生和栽培猪苓质量分别为1.87g,1.71g;猪苓多糖质量分别为0.51g,0.40g.
