Polyphenol content and antioxidant activities of Phellinus lonicericola in liquid culture
忍冬木层孔菌液体培养过程中多酚含量及抗氧化活性研究

Phellinus lonicericola is a medicinal fungus belonging to the Hymenochaetaceae. Few reports on the fungus were published previously. The changes of biomass and polyphenolic content in mycelia (intracellular polyphenol IP) and culture broth (extracellular polyphenol EP), and the varieties of antioxidant activities of mycelial extracts and culture broth were studied during the liquid culture of P. lonicericola. The results showed that the highest levels for mycelial biomass of P. lonicericola reached 8.33g/L at 168 and 216h, for IP 15.60mg GAE/g at 216h and EP 106.76mg GAE/L at 168h. The extracts of the mycelia showed antioxidant activity against DPPH radical with capacity positively related to the polyphenolic content.
