Abstract: In this study, the difference in the nutritional composition of the fruit bodies of Fomitopsis pinicola from different geographical regions (Jilin 1, Heilongjiang 1 and Yunnan 1) as well as its cultured mycelia was investigated by using various analytical methods. The results showed that the contents of carbohydrates, proteins, amino acids, fatty acids and mineral elements greatly differed among fruit bodies and cultured mycelia, and the contents of carbohydrates and fat in fruit bodies were higher than those in mycelia, whereas the opposite was seen for the contents of proteins and ash. These four samples were rich in amino acids, unsaturated fatty acids and trace elements (Zn, Fe, Mn and Cu). The contents of essential amino acids were ranked in the decreasing order of mycelia > Heilongjiang 1 > Yunnan 1 > Jilin 1, the proportions of unsaturated fatty acids in the decreasing order of Heilongjiang 1 > mycelia > Jilin 1 > Yunnan 1, and the contents of trace elements in the decreasing order of Heilongjiang 1 > Jilin 1 > mycelia > Yunnan 1.

Key words: Fomitopsis pinicola; fruiting bodies; cultured mycelia; nutritional constituents; quantitative determination and analysis
