In this study, we analyzed the nutrient composition and ${\beta}$-glucan content in Lentinula edodes fruiting bodies from different collection areas. Four types of free sugars were detected by HPLC, and the range of trehalose prevalence was 0.83% to 9%. The highest total amino acid content was observed from sawdust media cultivation of Lentinula edodes fruiting bodies, collected in China (JMI10050)The highest essential amino acid content, assessed by log cultivation of Lentinula edodes fruiting bodies, collected in Jangheung (JMI10059). Sixteen free amino acids were detected in Lentinula edodes fruiting bodies, and the major free amino acids were histidine, glutamic acid, and arginine. The highest essential amino acid including threonine, valine, methionine, isoleucine, leucine, phenylalanine, histidine, and lysine was fromsawdust media cultivation of Lentinula edodes fruiting bodies collected in China(JMI10052). The ${\beta}$-glucan content from log cultivation of Lentinula edodes fruiting bodies collected in Korea (JMI10059 and JMI10066) was higher than that from sawdust media cultivation of Lentinula edodes fruiting bodies collected in China. The highest ${\beta}$-glucan content was observed from log cultivation of Lentinula edodes fruiting bodies collected in Korea (JMI10066).
