Abstract: To analyze the function of Camellia oleifera Abel extracts in liquid medium on mycelium growth, metabolism of carbon, nitrogen and phenols in Agrocybe chaxingu Huang, dynamic changes in culture media was studied.Compared with the control (wheat bran-Potatoes medium without Camellia oleifera Abel extracts) , there have no difference on the dynamic changes of biomass and nutrition of culture.Furthermore, the total phenol content in culture medium was increased by adding 8%Camellia oleifera Abel extracts in liquid medium, but it did not affect mycelium and metabolism of carbon, nitrogen and phenols of Agrocybe mycelium in liquid culture medium.
