Abstract:
Six flavonoids, among them a new dihydroflavonol, 6,8-diprenylaromadendrin (1), and the flavonol 6,8-diprenylkaempferol (3), have been isolated from the organic extract of Monotes africanus. The isolated compounds containing a 5,7-dihydroxy-6,8-diprenyl system in the A ring of the flavonoid (1, 3, and 6) exhibited HIV-inhibitory activity in the XTT-based, whole-cell screen. In addition, several ¹³C NMR assigments of lonchocarpol A (6) were corrected.
