Abstract: To use Camellia oleifera branch in liquid culture for Agrocybe chaxingu Huang,the water soluble and ethanol extracted nutritive components of C.oleifera,were analyzed on their anti-oxidation.The results showed that total soluble phenolic content was higher in water extraction than in ethanol extraction.The water extraction of C.oleifera branch powder was rich in water-soluble phenolic compound,minerals and other nutrients.With UV/Vis analyses,the content of water soluble phenolic compounds in C.oleifera branch powder was 79.13μg·mL-1,its inhibition for peroxidation was 52.81% in egg yolk lipoprotein unsaturated fatty acid(PUFA) system,10.53% for superoxide radical scavenging.
