The Chemical Components in Morcella esculenta

Abstract

Three samples of Morcella esculenta which are collected from Japan, Germany and France were researched chemical components by gas-liquid chromatography (GLC) and high performance liquid chromatography (HPLC). The chemical components are general compounds (moisture, protein, lipid and ash) fatty acid, sterol and nucleotides compositions. The results obtained as follows: 1) The amounts of moisture, protien and lipid showed no changes among three samples, but the amount of ash in Japan was lower than those of two samples (Germany and France). 2) The fatty acid compositions (by GLC) of three samples were shown no changes, and the main fatty acids were cl6:0 (about 13%), cl8:1 (about 10%) and c18:2 (about 60%). 3) The sterol compositions by HPLC were similar Germany and France, ergosterol was about 35% and ergosta-5,7-dienol about 36%. The amounts of ergosterol in Japan were 15%, and there were lower than those of Germany and France. There were a lot of unknown sterols in Japan. 4) The amounts of 5'-GMP in nucleotide compositions, the amounts of Germany were five times than those of Japan. 5) General compounds, fatty acid and amino acid compositions of the mycelium in Japan were determined, and were compared with those of fruit bodies in Japan. The patterns of general compounds in mycelium were similar with those of fruit bodies. The patterns of fatty acid and amino acid compositions showed change.
