Özet
β-D-Fructopyranose (1), D-Xylopyranose (2), D-Mannitol (3), and flavonoids including quercetin-3-α-L-arabinofuranoside (4) and quercetin-3-O-glucopyranoside (5) were isolated from the leaves of Rhododendron luteum for the first time. Isolated compounds were identified using 1 D- (1H-NMR, 13C-NMR) and 2 D- NMR (HMBC, HSQC, COSY) spectroscopic techniques and comparison of the literature data. In our study, a relatively high amount of Quercetin-3-O-glucopyranoside was isolated (4%). As a result, our research showed that leaves of Rhododendron luteum could be a good source of monosaccharides, sugar alcohols and bioactive flavonoid glycosides.
