Abstract

The chemical constituents of the rhizomes ofBoesenbergia rotundaandKaempferia rotundawere investigated. A variety of phytochemicals have been isolated using various chromatographic techniques and their structures were identified spectroscopically. Three flavanones, i.e., pinostrobin, pinocembrin and alpinetin, and a chalcone, cardamonin, have been isolated fromB. rotunda, while three oxygenated cyclohexanes, i.e., crotepoxide, 3-deacetyl-crotepoxide and desoxypipoxide, together with a chalcone, 2’-hydroxy-4,4’,6’-trimethoxychalcone, were obtained fromK. rotunda.
