TL;DR: The structure of these compounds were determined by spectroscopic methods such as infrared (IR), nuclear magnetic resonance (A‚¹H, A‚¹A³C and 2D NMR) and gas chromatography - mass spectrometry (GC-MS) and by comparison with the data reported previously as mentioned in this paper.
Abstract: Twelve extracts from four Zingiberaceae species (Curcuma xanthorrhiza, Curcuma heyneana, Kaempferia angustifolia and Kaempferia rotunda) have been screened for antimicrobial assay and cytotoxic screening. Curcuma xanthorrhiza showed strong activity in all biological assays. Two cyclohexane diepoxides, crotepoxide and boesenboxide, together with 2'-hydroxy-4,4',6'-trimethoxychaIcone were isolated from the rhizomes of Kaempferia angustifolia. The structure of these compounds were determined by spectroscopic methods such as infrared (IR), nuclear magnetic resonance (A‚¹H, A‚¹A‚³C and 2D NMR) and gas chromatography - mass spectrometry (GC-MS) and by comparison with the data reported previously.
