ABSTRACT:
Provided is a process for preparation of aRhus vernicifluaextract, comprising extracting allergen-removedRhus vernicifluawith a soluble solvent, thereby obtaining an extract, subjecting the thus-obtained extract to ultrafiltration to remove high-molecular weigh substances, concentrating and drying the resulting material, thereby obtaining extract powder and irradiating far-infrared to the extract powder, thereby improving anti-cancer activity. TheRhus vernicifluaextract prepared according to the process of the present invention exhibits superior anti-cancer activity.
