Abstract
A new flavan-3-ol glycoside, compound 1 (careyarboside A), was isolated from the ethanol extract of the stems of Careya arborea, together with six known compounds. Of these, three phenolic glycosides (leonuriside A, picraquassioside D, and careyarboside B) have never been previously isolated from genus Careya and family Lecythidaceae. Their chemical structures were identified using spectroscopic data, specifically HRESIMS, 1D and 2D NMR data, including 1H-1H COSY, HSQC, and HMBC. In addition, the chemical structures of the known compounds were identified through spectral comparisons with those of published values.
