Abstract:
The content of nutrient components of fruit body and mycelium from Ramaria botrytoides were investigated in this study by national standards and common methods, and the content of active substances (polysaccharides and polyphenols) and their antioxidant activities were also evaluated. The results showed that the carbohydrate content of fruit body and mycelium was 38.74±1.27% and 63.55±3.17%, the fat content was 2.52±0.14% and 3.21±0.19%, the protein content were 11.02±1.21% and 22.30±1.18%, and the ash content was 5.77±0.14% and 5.98±0.11%, respectively. Except Mg, the content of mineral elements in fruit body was generally higher than that in mycelium, and the content of essential amino acids in mycelium (7.08±0.15)g/100 g) was higher than that in fruit body((2.55±0.24) g/100g). In addition, the content of polysaccharides in mycelium ((35.51±1.78) mg/g) was higher than that in fruit body ((23.22±1.60) mg/g) while the content of polyphenols in fruit body ((6.85±0.41) mg/g) was higher than that in mycelium ((3.66±0.29) mg/g). The antioxidant activities of polysaccharides and polyphenols from fruit body and mycelium were in the following order: polyphenols from fruit body> polyphenols from mycelium> polysaccharides from mycelium> polysaccharides from fruit body. The results indicated that the polysaccharides from fruit body were expected to be replaced by the polysaccharides from mycelium in medicine and food, and the polyphenols from mycelium would still need further development and utilization.
