INVESTIGAÇÃO DO POTENCIAL ANTIFÚNGICO DE Sida planicaulis Cav. (Malvaceae) frente FUNGOS FILAMENTOSOS.

Sida planicaulis, popularly known as "vassoura", is very common in Curimataú Paraibano, although little studied in relation to its antimicrobial potential. This study aimed to investigate the antifungal activity of the crude ethanolic extract and its phases: hexane, chloroform, aceto- and hydroalcoholic phase of the plant on the filamentous fungi Rhizopus oryzae, Exophyala werneckii, Aspergillus niger, Aspergillus flavus, Trichophyton mentagrophytes, Cladosporum 2B3 and Microsporum canis. The antifungal activity was verified by the propagation technique in Agar. Incubation was carried out in a bacteriological oven at 28°C for 7 to 15 days. The antifungal activity was evaluated by the values of the inhibition halos, the concentration of the Minimal Inhibitory by the microdilution technique, where all testes were performed in triplicate. The results showed antifungal activity against the microorganism Trichophyton mentagrophytes, the values of the inhibition halos varied between 15 and 36 mm, Third, species of extract and phases are not an antifungal activity. It can be concluded that the samples used are specific to the inhibitory plane against the fungus T. mentagrophytes, but did not obtain the units used for the development of a new antifungal.
