The optimun conditions of polyphenol extaction from seed of camellia oliefera were stuied. Experiments of solvent extaction comparison test were carriedout. Furthermore,The orthgonalexperiments were carry out based on single factors including concentration of methanol, extracting temperature, time, exraction period and ratio of material to solvent. Total phenolic compouds were determimd by the Folin-Ciocahue methed. The results indicated that the optimum extractimg comdition of Camellia oliefera as follows, methanol 60% , temperature 40 ℃ , extract...
