Mycelia powder of Ganoderma capense.a kinds of medicinal fungi of Ganodermataceae was studied in this paper.Analytic results showed that contents of humidity,protein,fat,total carbohydrate,crube(dietary)fiber,reduce sugar and ash(mineral matter)were double more then the fruitbodies of Ganoderma lucidum or G.sinense.Eighteen kinds of amino acids,totaled 10.34～10.47g/100g,The fatty acid composition includes oleic acie,linoleate,linolenic acid,palmitic acid and others and nonsaturated fatty acids made up the majority(78.9%).The appraised results of safety toxicology showed that the mycelia powder was safe for taking orally,nonpoisonous in reality:without any harmful effects and free from side effects to the growth of SD mice and any effects of pathological changes and causing mutation,and the lethal dosage(LD50)was more than 20g/kg by orally(to Kunming mice).It was considerded that the mycelia powder was completely in accordance with the demands of functional food,and try to request some function of health protection according to its known pharmacological efficacity.
