Study on the Bacteriostatic and Bactericidal Activity of Extract from Schisandra Chinensis extract.

The aim was to study the bacteriostatic activities of extract from Schisandra Chinensis extract and provide references for its reasonable development.


[Method] Schisandra Chinensis extract were stirred and extracted with 3 kinds of solvents such as 70% ethanol,60% acetone and boiling water.With Staphylococcus aureus as tested bacteria,minimumm inhibition concen.(MIC) was determined by agar doubling dilution method and maximum bacteriostatic concen.(MBC) was measured by tube doubling dilution method.


[Result]Three extracts of Schisandra Chinensis extract had significant anti-microbial activity on S.aureus,that of 60% acetone was most obvious,the second was extracts of 70% ethanol and the last was that of boiling water.Their MIC was 25,50 and 100 mg/ml resp.The bacteriostatic effect of extract of acetone with low concen.was not obvious.The extract at 62.5 mg/ml could inhibit bacterial the growth completely,but had not obvious bactericidal effect.The MBC of extract of acetone was 125 mg/ml.


[Conclusion]The acetone of Schisandra Chinensis extract had obvious bacteriostatic and bactericidal activity.
