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.
