Patent ID: 7473435

Claim:
A method for isolating a bioactive fraction derived from cell juice of a Camellia plant, said method comprising: providing fresh biomass of Camellia plant, wherein said fresh biomass comprises fresh Camellia plant biomass that has not undergone conventional tea processing; separating the fresh biomass of the Camellia plant into cell juice and a cell walls component, wherein said separating comprises grinding, macerating, and pressing the fresh biomass to separate the fresh biomass into the cell juice and the cell walls component; treating the cell juice under conditions effective to yield a bioactive fraction, said conditions comprising subjecting the cell juice to microwave treatment to induce coagulation, thereby yielding a coagulated membrane fraction and a non-coagulated portion of the cell juice, wherein said bioactive fraction is selected from the group consisting of a membrane fraction, a membrane fraction extract, a cytoplasm fraction extract, and a cell juice serum; and isolating said bioactive fraction from the treated cell juice.
