Abstract

Several fractions of a methanol extract from the leaves of Aristolochia paucinervis Pomel (Aristolochiaceae) were screened for their antidermatophytic efficiency against different human pathogenic fungi responsible for tinea and other skin infections. The antifungal study was carried out by the macrodilution agar method and the results showed that, with the exception of the aqueous fraction, all the fractions exhibited antifungal activities against the dermatophytic fungi tested. The hexane fraction was found to be the most effective (MIC range: 64-2048 µg/mL), whereas the butanol fraction was the least active (MIC range: 1024 µg/mL to more than 2048 µg/mL). The most susceptible fungi were Epidermophyton floccosum and Trichophyton violaceum in contrast to Trichophyton mentagrophytes and Trychophyton rubrum which were less sensitive to the fractions tested. The effects were compared with those of ketoconazole, amphotericin B and griseofulvin, for which MIC ranges were, respectively, 0.12-4 µg/mL, 0.5-4 µg/mL and 0.5-2 µg/mL.

Abstract

The anti-Helicobacter pylori effect of the extracts and the fractions obtained from Aristolochia paucinervis rhizome and leaves were studied against a reference strain of H. pylori by using the agar dilution method. Only the methanol extracts and the hexane fractions of either the rhizome or the leaves exhibited an inhibitory activity at a concentration of ≤128 μg/ml. The leaf hexane fraction APLH demonstrated a higher inhibitory activity (MIC: 4 μg/ml) than the rhizome hexane fraction APRH (MIC: 16 μg/ml), the leaf methanol extract APLM (MIC: 32 μg/ml) and the rhizome methanol extract APRM (MIC: 128 μg/ml). This inhibitory activity was confirmed for the active extracts and fractions against clinical isolates of H. pylori (n=20) for which MIC50 and MIC90 were determined.
