- Abstract
The effect of different solid media on the qnality of Cordyceps militaris fiuit body was stndied by detecting the growth, cordycepin, cordyceps acid, cordyceps polysaccharide, 1,1-diphenyl-2-picrylhydrazyl (DPPH) and 2,2'-azino-bis-3-ethylbenzothiazoline-6-sulfonic acid (ABTS) free radical scavenging capacity of C. militaris fiuit bodies cultured on different solid media. TI1e results showed that the active substances and antioxidant activities of tlie C. militaris fiuit bodies were significantly different (P<0.05). Among tliem, the growth of C. militaris fiuit body cultured on tlie millet and wheat bran medium was better, the budding time was the fastest of only 12 d, the fiuit body was the longest, reaching (6.50±0.15) cm, fue fresh weight was the heaviest, reaching (8.58±0.07) g, and the cordycepin and cordyceps acid content was the highest, reaching (6.53±0.06) mg/g and (7.66±0.21) mg/g, respectively. The content of cordyceps polysaccharide in C. militaris fiuit body cultured on the myotonin medium was tlie highest, reaching (59.07± 1.89) mg/g. The antioxidant activity was the strongest on the myotonin and wheat bran medium, the scavenging rates ofDPPH and ABTS free radical were (66.84±0. 77)% and ( 68.28±0.26)%, respectively.
