Article abstract of DOI:10.1016/0031-9422(91)85273-3

Three new harpagide derivatives have been isolated from the aerial parts of Rogeria adenophylla (Pedaliaceae).Their structures have been established as 8-O-cis-cinnamoylharpagide, 8-O-cis-cinnamoyl-6-O-β-D-glucosyl-harpagide and 6'-O-p-coumaroyl harpagide respectively, the p-coumaroyl moiety of the latter existing in either the trans or cis configuration.In addition, harpagide, harpagoside, 8-O-trans-p-coumaroylharpagide, procumbide and verbascoside have been isolated and identified.
