Pineapple bark extract prepared in various concentrations of 10%, 15%, 20% and 25%, then test the inhibition ofTrichophyton mentaghrophytesand incubated temperature 25o C for 5day. Based on the results obtained percentage pineapple skin extractfungal inhibition test Trichophyton mentaghrophytesthe concentration 10%, 15%, 20% and 25%, respectively, are22%, 37%, 46% and 56% compared to the positive control.Based on this research, pineapple bark extract containing flavonoids, phenolics, saponins, triterpenoids, steroids and alkaloids. The results of this study can be concluded that the extract of pineapple skin Trichophyton mentaghrophyteswhich is characterized by the formation of inhibit zone.]]>
