From the hexanic extract of the stem from Swartzia apetala Raddi var. glabra were isolated one stilbene (1), one flavanone (2), one pterocarpan (3), one triterpene (4) and a mixture of three steroids (5 to 7). The crude extract and the compounds isolated were submitted to evaluation of the antifungal activity against nine yeast standard ATCC of the Candida genus. Among the compounds only the triterpene (4) and the mixture of steroids (5 to 7) showed no activity. The structures of the compounds were determined by spectral data analysis of GC/MS and ¹H and 13C NMR (1D and 2D experiments), as well as comparison with literature values.
