    Abstract：The extraction method of chlorogenic acid(CGA) from the crude honeysuckle powder is studied. The distribution coefficient D indicated: Ethyl acetate was the most suitable extractant for CGA's purification. After 4-stage extractions, test date showed that CGA's content of the product were 35.2% and 69.1% by HPLC and UV respectively. The experimental CGA recovery ratio was almost 90%. The product was determined containing CGA's isomer and isochlorogenic acid by LCMS test. ......
