Study on activity contents and bacteriostasis function of Lithocarpus polystarch
Object:study on extracting of the flavones and bacteriostasis function of Lithocarpus polystarch.Method:Selected different extraction solvent extraction many leaves of Lithocarpus polystach the active constituent.Using two time of dilution methods,to Proteus vulgaris,Escherichia coli,Staphylococcus aureus,Sarcina lutea,Bacillus subtilis,Enterococcus faecalis,Monilia albican conducte the bacteriostasis research.Determines the best extraction solvent determination bacteriostasis the lowest density.Result:Discovered many of Lithocarpus polystach for tries the mold mushroom spawn to 6 kinds to have the varying degree inhibitory action,did not have the bacteriostasis function to the Monilia albicans.In different extracting liquid,bacteriostasis function of 70% ethanol solution was obvious,the MIC was 0.03125 g/mL.
