This paper reports the isolation of two undescribed phenolic glycosides ( 1 and 2 ), together with seven known compounds ( 3 - 9 ) from the branches of Viburnum chinshanense . The structures of undescribed compounds were elucidated by comprehensive spectroscopic methods (1D NMR, 2D NMR, and HRESIMS). The sugar units of compounds 1 and 2 were identified by acid hydrolysis and HPLC analysis of the chiral derivatives of the monosaccharides. Furthermore, the α ‑amylase and α -glucosidase inhibitory activities of all isolates were evaluated and compounds 1 , 5 , and 8 displayed potential α ‑amylase and α -glucosidase inhibitory activities. The molecular docking analyses of compounds 1 and 8 with the potent inhibition towards the target enzymes were also performed. |
