Abstract | Full Text

Chemical constituents of rhizomes of Alpinia oxymitra (Zingiberaceae) were investigated. Usingchromatographic techniques, two known flavonoids, epicatechin and galloepicatechin, were isolated together with a new calamenene sesquiterpene, (–)-(1R,4S)-8-hydroxy-13-calamenenoic acid. Structure elucidation of theisolated compounds was accomplished by means of spectroscopic techniques, especially NMR spectroscopy andmass spectrometry.
