摘要
The optimal cultivation conditions and chemical components of Poria cocos fruiting bodies were examined by employing the single factor and response surface methods to screen for optimal conditions for artificial cultivation. The differences in chemical composition among the fruiting bodies, fermented mycelium, and sclerotia of P. cocos were compared using UV spectrophotometry and high-performance liquid chromatography (HPLC). The optimal growth conditions for P. cocos fruiting bodies were 28.5°C temperature, 60% light intensity, and 2.5 g pine sawdust, which resulted in the production of numerous basidiocarps and basidiospores under microscopic examination. Polysaccharides, triterpenoids, and other main active components of P. cocos were found in the fruiting bodies, sclerotia, and fermented mycelium. The triterpenoid components of the fruiting bodies were consistent with those of the sclerotia. The content of pachymic acid in the fruiting bodies was significantly higher than that in the sclerotia, with a value of 33.37 ± 0.1902 mg/g. These findings provide novel insights into the sexual breeding and comprehensive development and utilization of P. cocos.
