Abstract
We describe the isolation, identification, and structural elucidation of natural products from the Mongolian me- dicinal plant Polygonatum odoratum (Mill.) Druce. Six flavonoid glycosides, isorhamnetin-3-O-rutinoside (narcissoside, narcissin) (1), kaempferol-3-O-rutinoside (nicotiflorin) (2), quercetin-3-O-rutinoside (rutin) (3), apigenin-6-C-� -D- glucoside (isovitexin) (4), apigenin-6-C-(2�� -O-� -D-xylopyranosyl-� -D-glucopyranoside) (desmodin) (5), and isovitexin-7- O-� -D-glucoside (saponarin) (6), were isolated from the aerial parts of Polygonatum odoratum (Mill.) Druce. The struc- tures of 1-6 have been confirmed by UV, IR, MS, and NMR ( 1 H, 13 C, COSY, HSQC, HMBC, NOESY, and ROESY) data. Graphical Abstract:
