ABSTRACT
OBJECTIVE To find the active principle in Radix Scutellariae,Radix Sophorae Flavescentis and Flos Lonicerae in Gansu inhibiting yeast-like fungi of deep infection.METHODS Radix Scutellariae,Radix Sophorae Flavescentis and Flos Lonicerae were separately cleaned,toasted and grinded to fine power.Five kinds of(8 strains) yeast-like fungi that were collected and spread into 90mm Sabouraud plate.On aseptic condition,bored holes on Sabouraud plate with the drilling instrument of 6mm diameter,and filled every holes with 25.73mg fine powder of Radix Scutellariae,Radix Sophorae Flavescentis and Flos Lonicerae,and added 3 to 5 drops of distilled water in the medicinal powder.Under 35℃,the bacteria were cultured for 24 to 48 hours,and the size of bacteriostatic ring was observed.RESULTS The diameters of the bacteriostatic ring of Radix Scutellariae powder inhibiting five kinds of yeast-like fungi were separately 16.0mm,13.5mm,13.0mm,13.0mm and 10.5mm,respectively,and the diameter of Radix Sophorae Flavescentis and Flos Lonicerae powder was 0.CONCLUSIONS There is the active principle inhibiting yeast-like fungi in Radix Scutellariae,but not that in Radix Sophorae Flavescentis and Flos Lonicerae.
