A new polyoxygenated cyclohexene, globbanol A (1), 2 other cyclohexene derivatives, crotepoxide (2) and boesenboxide (3), along with a chalcone, 2ʹ- hydroxy-4,4ʹ,6ʹ-trimethoxy-chalcone (4) were isolated from the rhizomes of Globba pendula Roxb. ( Zingiberaceae) of Vietnam. Their structures were elucidated on the basis of extensive analysis of high-resolution electrospray ionization mass spectrometry and NMR spectral data. Absolute configuration of new compound was determined by circular dichroism spectra. All these compounds are first reported from the genus Globba.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
