Popis: | Chrysoeriol-7-O-β-d-glucopyranoside (1), luteolin-7-O-β-d-glucopyranoside (2), quercetin-3-O-β-d-glucopyranoside (3), quercetin-3-O-β-d-galactopyranoside (4), and quercetin-3-O-α-l-rhamnopyranoside (5) were isolated for the first time from the fruits of Rhus parviflora. The chemical structures of the compounds were determined using nuclear magnetic resonance, fast atom bombardment mass spectrometry, and infrared spectroscopy. Compound 4 (hyperin) inhibited cyclin dependent kinases (CDK2 and CDK5) in vitro with IC50 values of 21.02 and 10.28 μM, respectively. |
