(-)-(3S,4R,5S,7S)-5-Benzoyloxymethyl-6-oxadicyclo-<4,1,0>hept-1-ene-3,4-diol 3-benzoate <(-)-pipoxide> and the two (+)-zeylenol related substances, (-)-(1R,2S,3R,4S)-2-benzoyloxymethylcyclohex-5-ene-1,2,3,4-tetrol 1,4-dibenzoate, and (1R,2S,3R,4S)-2-hydroxymethylcyclohex-5-ene-1,2,3,4-tetrol 1,4-dibenzoate, together with 2'-hydroxy-4,4',6'-trimethoxychalcone, were isolated from the rhizomes of Kaempferia angustifolia, in addition to crotepoxide, boesenboxide and (+)-zeylenol.The rhizomes of an unnamed Kaempferia species have also been found to contain the zeylenol derivatives. - Keywords: Kaempferia angustifolia; Kaempferia sp.; Zingiberaceae; (-)-pipoxide; oxygenated cyclohexane; (+)-zeylenol.
