Tóm tắt

Annona reticulata L. is a small deciduous tree species of Annonaceae, traditionally used for treatment of various ailments. The present study investigated the chemicals of the leaves of Annona reticulate and identified three compounds, including taraxerol (1), fridelin (2), and myricetin-3-O-α-L-rhamnopyranoside (3), using NMR spectroscopy. Among them, fridelin (2) is isolated first time from this species. The extracts and purified compound (3) were subjected to the examination of their effects on fungal activity with two fungi strains (Fusarium oxysporum and Pyricularia oryzae) using disc diffusion method. The results demonstrate beneficial effects of Annona reticulata as the antifungal activity for medicinal usages.
