GRAPHICAL ABSTRACT

ABSTRACT

Four new polyoxygenated cucurbitane triterpene glycosides named kedrojiftene A-D (4-7), were isolated via different chromatographic techniques along with three phenolic compounds (1-3) from the crude extract of Kedrostis gijef. The isolated compounds were elucidated based on 1D, 2D-NMR spectroscopic analyses, HRESIMS and comparison with the related metabolites in literature. In bioassay, the α-glucosidase inhibitory assay for the isolated compounds was carried out and compounds (1-3) showed significant inhibitory activities.
