The nutrients and bioactive compounds in the fruiting bodies of Trametes orientalis(Yasuda) Imazeki were determined by national standards and common methods. The results revealed that the contents of moisture, proteins, total carbohydrates, fat, ash, water-soluble polysaccharides and triterpenes in dried T. orientalis were(11.25 ± 0.34)%,(18.01 ± 0.25)%,(62.21 ± 1.3)%,(1.58 ± 0.042)%,(4.20 ± 0.15)%,(7.29 ± 0.17)%, and(3.52 ± 0.11)%, respectively. The eight essential amino acids account for 39.70% of the total amount of eighteen amino acids, and the ratio of essential amino acids to non-essential amino acids was 0.66. The contents of Ca, Mg, Fe, Zn, Mn, and Cu were(816.9 ± 8.5),(456.0 ± 11),(187.0 ± 3.7),(6.0 ± 0.14),(24.5 ± 0.83), and(3.9 ± 0.091) μg/g, respectively. Both water-soluble polysaccharides and triterpenes of T. orientalis exhibited potent antioxidant capacity in a concentration-dependent manner. T. orientalis may be developed as nutraceutical and pharmaceutical products due to its high protein and mineral contents, low content of fat, appropriate amino acid composition, and high water-soluble polysaccharides and triterpenes.
