Schltr. [currently known as Boesenbergia rotunda (L.) Mansf., Kulturpfl.]. Their structures were assigned on the basis of their spectroscopic data. (-)-Hydroxypanduratin A and (-)-panduratin A showed significant topical anti-inflammatory activity in the assay of TPA-induced ear edema in rats. © 2002 Elsevier Science Ltd.
