Further investigation of the petrol extract of Piper cubeb yielded two new minor oxygenated cyclohexanes, (-)-rel-(2S,3R,4R,5R)-2,3,4,5-tetraacetoxy-1-benzoyloxy methylcyclohex -1(6)-ene-2,3,4,5-tetrol[(-)-piperenol C] and (+)-(2S,3R,4R,5R)-2,4,5-triacetoxy-1-benzoyloxy methylcyclohex -1(6)-ene-2,3,4,5-tetrol-3-benzoate[(+)-piperenol A-triacetate]. In addition, two rare neolignans have been isolated for first time from this species and identified as (-)-kadsurin A and (-)-piperenone.
