Effects of different cultivation conditions on physiological properties and total flavonoids content of Pleurotus citrinopileatus
In order to study the effect of different cultivation conditions on the physiological characteristics and total flavonoid content of Pleurotus citrinopileatus,the total flavonoid was extracted from 13 kinds of P. citrinopileatus under different cultivation conditions by ultrasonic-assisted extraction method,and the color analysis was carried out by sodium nitrite and aluminum nitrate. The results showed that the linear relationship was good at 510 nm(R2=0.9959). Flavonoids were detected in the P. citrinopileatus under different cultivation conditions. In different light treatments,the total flavo-noid content of natural light treatment was the highest(22.607 mg·g-1),while the red light treatment was the lowest (14.667 mg·g-1). Among different cultivation materials,the mixed cultivation material treatment had the highest total flavonoid content of 22.007 mg·g-1,while the corn cobs treatment had the lowest of 17.663 mg·g-1. In the analysis of total flavo-noid content in different parts,the content of total flavonoid in the cap of P. citrinopileatus was the highest(25.154 mg·g-1),while the content of total flavonoid in the fungal seat was the lowest(13.918 mg·g-1). Different cultivation conditions had influence on the flavonoid content and physiological characteristics of P. citrinopileatus. Cultivation conditions directly or indirectly affected the accumulation and transfer of flavonoid in the body.
