Hypsizigus marmoreus is a wild mushroom commonly consumed in South Korea due to its beneficial effects on health. In the present study, the general chemical and inorganic-element composition, the total amino acid contents, and the volatile-flavor compounds of H. marmoreus were investigated for food uses. The proximate compositions consisted of 60.1% carbohydrate, 32.0% crude protein, 8.98% moisture, 5.0% ash, and 2.0% crude lipid. The minerals in H. marmoreus were found to be as follows; potassium (429.5 mg), phosphorus (101.9 mg), sodium (20.3 mg), magnesium (54.86 mg), calcium (2.7 mg), zinc (0.8 mg), iron (0.7 mg), manganese (0.2 mg), and copper (0.1 mg), based on 100 g of mushroom dry weight. Seventeen kinds of total amino acids were found in H. marmoreus, with the glutamine acid content being the highest (2,340 mg/100 g), followed by the asparagine, serine, arginine, and leucine contents. The volatile-flavor components of H. marmoreus were collected via simultaneous steam distillation extraction (SDE), and were analyzed via gas chromatography-massspectrophotometry (GC-MS). A total of 17 volatile-flavor compounds were identified, including eight aldehydes, seven alcohols, one acids, and one other compounds. The most abundant compound was 2,3,6-trimethyl pyridine, which accounted for more than 40% of the total volatiles; other important compounds were 1-octen-3-ol, butylhydroxytoluene (BHT), isooctyl phthalate, 3-octanal, 1-undecanol, and 2-amylfuran. These results provide preliminary data for the development of H. marmoreus as an edible food material.
