Abstract: Using ursolic acid as reference substance,content of total triterpenic acid in Crataegus pinatigide Bge was determined by colorimetric method. Results showed that the content of triterpenic acid is over 80%. The average recovery rate is 97.70% with RSD 1.06%. Meanwhile using rutin as reference substance,content of total flavonoids in Crataegus pinatigide Bge was also determined by colorimetric method of aluminium nitrate. Results showed there is good linearity between content of total flavonoids and absorbance. The average recovery rate is 97.12% with RSD 2.91%.

Key words: Crataegus pinatigide Bge, ursolic acid, rutin
