實物特徵:The tree Fagara monophylla ranges throughout Tropical America. The genus Fagara has a diversity of alka-loid compounds with antibiotic properties; nevertheless, there are few reports antifungal activity of its organic compounds. Organic extracts from Venezuelan F. monophylla were tested for antimicrobial activity against Aspergillus terreus, A. flavus, Penicillium digitatum, P. funiculosum, P. citrinum, Paecilomyces and Candida albicans. Minimal Inhibitory Concentration (MIC) was determined. The susceptibility trials of organic fractions (Hex., CH2Cl2 and MeOH) showed that the highest inhibition was presented by MeOH against A. flavus (55 mm), P. digitatum (60 mm), P. funiculosum (56 mm)and C. albicans (26 mm). The activities of MeOH/EtOAc fractions 1 and 2 suggest a combined effect against A. flavus, P. digitatum and P. funiculosum. The MIC of 1 MeOH/ EtOAc subfraction activity was lower against C. albicans (32 μg/ml) and moderate (128 μg/ml) against P. digitatum. This organic extract has a great antifungal potential. The phytochemical proves and TLC testing on the organic extract, and the MeOH/EtOAc subfraction, respectively, indicated the presence of alkaloid com-pounds.
