Abstract:

We describe the isolation, identification, and structural elucidation of natural products from the Mongolian medicinal 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-β-Dglucoside (isovitexin) (4), apigenin-6-C-(2''-O-β-D-xylopyranosyl-β-D-glucopyranoside) (desmodin) (5), and isovitexin-7- O-β-D-glucoside (saponarin) (6), were isolated from the aerial parts of Polygonatum odoratum (Mill.) Druce. The structures of 1–6 have been confirmed by UV, IR, MS, and NMR (¹H, ¹³C, COSY, HSQC, HMBC, NOESY, and ROESY) data.
