Abstract: A debittering Kudingcha extract, a preparation method and a fingerprint detection method thereof are disclosed, which relates to the technical field of extract preparation and detection. The extract is prepared from Kudingcha by enzymolysis, water extraction, concentration, drying, purification and enrichment by a macroporous resin column, and drying.
