Abstract:To provide scientific basis for further development resources of Sanguisorba officinalis，The total triterpenes of Sanguisorba officinalis were extracted by hot water extraction and ethanel precipitation，reflux extraction and impregnation method.And antioxidant activities of total triterpenes from Sanguisorba officinalis were evaluated by 1，1-diphenyl-2-trinitrophenylhydrazine method.The result indicated that the content of total triterpene from Sanguisorba officinalis obtained by the three extraction methods was as fallows：reflux extraction（88.66mg/g）＞ impregnation（55.26mg/g）＞ hotwaterextractionandethanelprecipitation（44.31mg/g）.The total triterpenes of Sanguisorba officinalis and vitamin C had the DPPH radical scavenging ability with IC50 of 3.04 g/mL and 5.46 g/mL.The content of total triterpenoids from Sanguisorba officinalis was the highest by reflux extraction，and the scavenging ability of total triterpenoids from Sanguisorba officinalis by reflux extraction had more antioxidant activity compared with the commonly used antioxidant vitamin C.Moreover，the total flavonoids content from leaves had more antioxidant activity compared with the commonly used antioxidant vitamin C.
