Studies on the Constituents of Higher Fungi of Korea

한국산 고등 균류의 성분에 관한 연구

Free amino acids in extracts and total amino acids in hydrolysates of eight species of higher fungi were analyzed by an amino acid autoanalyzer. Twenty amino acids were analyzed in eight species of higher fungi. 1) of all free amino acids contained in higher fungi, alanine is the richest, and then comes glutamic acid, serine, arginine, proline and histidine in that order. Of all total amino acids contained in higher fungi, glutamic acid is the richest, and then comes proline, valine, aspartic acid, alanine, leucine in that order. Especially Russula fragilis and Lepiota procera contain large quantity of glutamic acid. 2) Gross contents of free amino acids in the extracts is high in order of Lepiota procera, Phylloporus rhodoxanthus, Russula fragilis, Tylopilus felleus and total amino acids in hydrolysates is high in Phylloporus rhodoxanthus, Lepiota procera, Russula fragilis, Lentinus lepideus. 3) Total amount of essential amino acids in the extracts was high in Lepiota procera, Phylloporus rhodoxanthus, Tylopilus felleus, Xylaria hypoxylon, Lentinus lepideus, Russula fragilis, Lactarius piperatus and Calocybe gambosa and in the hydrolysates of Phylloparus rhodoxanthus, Russula fragilis, Lepiota procera, Tylopilus felleus, Lentinus lepideus, Lactarius piperatus, Calocybe gambosa and Xylaria hypoxylon in that order, respectively.
