Abstract: Objective: To provide a reference data for the development and utilization the wild of Auricularia peltata,the contents of nutritional and active components of its sporophore were determined. Methods: National standards method was used to determine contents of nutritional components and active material in sporophore of A. peltata. Results: The results showed that contents of water,ash,crude fats and dietary fiber in sporophore of A.peltata were( 126.2 ± 0.03) mg / g,( 381.2 ± 0.21) mg / g,( 2.5 ± 0.09) mg/g and( 331.8 ± 0.74) mg/g( water soluble dietary fiber( 88.6 ± 0.16) mg/g,insoluble dietary fiber( 243.2 ±0.58) mg / g),respectively.The crude protein content was( 145.8 ± 0.72) mg / g dry wild A.peltata.The wild A.peltata contained20 amino acids including 8 essential amino acids,the content of essential amino acid in total amino acid was 33.93%( 11.27 mg/g dry A.peltata vs 33.22 mg/g dry A.peltata). Furthermore,the results indicated that contents of vitamin C and mannitol in sporophore of A.peltata were( 35.2 ± 0.12) mg / g and( 2.4 ± 0.01) mg / g,respectively,while content of polysaccharid was( 12.7 ± 0.03) mg / g. Conclusion: A.peltata may be developed as nutraceutical and pharmaceutical due to its high protein,dietary fiber content and low content of fat.
