Abstract

The invention discloses a Japanese picris japonica extract and an extracting method thereof. The extractive comprises a water elution part of a water extract of the Japanese picris japonica and total flavone. The extracting method of the water elution part of the water extract of the Japanese picris japonica comprises the following steps of: adding distilled water of a quantity of 15-20 times of the Japanese picris japonica to extract the Japanese picris japonica; combining extracting solutions, centrifuging and taking the supernate; concentrating to a concentration of 1g raw medicinal material per ml, separating and eluting through resin; and concentrating the eluent. The extracting method of the total flavone of the Japanese picris japonica comprises the following steps of: extracting the Japanese picris japonica with 30-60 percent alcohol of a quantity of 20-30 times; centrifuging and then concentrating the extracting solution until no alcohol residue; diluting to a concentration of 1g raw medicinal material per ml with water and then depositing off polysaccharide with 95 percent alcohol of a quantity of 3-5 times; taking the supernate, concentrating and evaporating to dryness;dissolving with water until the concentration of flavone is 20-30mg / ml; separating through resin, and eluting respectively with water and alcohol; and remaining the alcohol eluting part. The Japanesepicris japonica extract can be used for medicaments for reducing blood sugar.
