摘　　要：对林芝的2份味美味牛肝菌样品,采用常规分析方法,进行蛋白质、粗脂肪、粗纤维、总糖、灰分、水分、矿物质元素和氨基酸等营养成分分析。结果表明,2份美味牛肝菌富含粗纤维、矿物质、蛋白质及氨基酸;在矿物质元素中,钠、镁、铜和锰含量的差别较小,钾、钙、铁、锌、硒和铬含量的差别较大,钾和钙的含量相对较高,铅和汞未检出,镉和砷在限量值内;8种必需氨基酸占氨基酸总含量的40.22%,必需氨基酸与非必需氨基酸的质量比为0.67,9种药用氨基酸占氨基酸总量的60%以上。With two samples of Boletus edulis fromLinzhi of Tibet as raw materials, use conventional analysis methods to analyze nutrients including protein, crude fat, crude fiber, carbohydrate, ash, moisture, mineral elements and amino acid. The results showed that two samples of Boletus edulis were rich in crude fiber, minerals, protein and amino acid. In mineral elements, the differences of content of sodium, magnesium, copper and manganese were less, but the differences were greater in contents of potassium, calcium, iron, zinc, selenium and chromium, the contents of potassium and calcium were relatively higher, the contents of lead and mercury were respectively zero, the contents of cadmium and arsenic were respectively less limited value. Eight kinds of essential amino acids accounted for 40.22% of the total amino acid quality, mass ratio of essential amino acid and non-essential amino acid was 0.67, and nine kinds of medicinal amino acids accounted for more than 60% of the total amino acids quality.
