Two new xanthones, namely caledonixanthones E (1) and F (2), were isolated from the stem bark of Calophyllum caledonicum (Guttiferae). The structural elucidation of these compounds was mainly established on the basis of 1D, 2D NMR and HRMS spectroscopic analysis. Among the isolated compounds, eight other known xanthones were also identified in the course of this phytochemical study. In addition to this report, a preliminary evaluation of the antifungal properties of these polyphenolic compounds against Aspergillus fumigatus and Candida albicans is presented.
