The seeds of Aframomum hanburyi K. Schum. (Zingiberaceae) are used as an antidote and ingredient in certain medicinal preparations in Cameroon [93]. From an acetone extract of the seeds of this plant, two sweet dihydroflavonols, 3-acetoxy-5,7-dihydroxy-4 -methoxyflavanone (68) and 2/ ,3/ -(+)-3-acetoxy-5,7,4 -trihydroxyflavanone (69), were isolated [93]. 3-Acetoxy-5,7-dihydroxy-4 -methoxyflavanone (68) was previously isolated from a different species, Aframomum pruinosum Gagnepain [112]. However, the sweetness intensities of these compounds were not indicated [93,112].
