Xanthone and antifungal constituents from Monnina obtusifolia.
Three biphenyls and four xanthones have been isolated from the aerial parts of Monnina obtusifolia. The structures were established on the basis of their spectral data and that of some derivatives. The biphenyls have been isolated previously from the same genus. 1,3,6-Trihydroxy-2,5-dimethoxyxanthone is a new natural product, whereas the other xanthones have been described in other species. The antifungal activity of the isolated compounds has been determined.
