Abstract: A novel flavone glycoside, 3′″-carbonyl-2″-β-L-quinovosyl icariside Ⅱ was isolated from a Chinese medicinal plant, Epimedium koreanum Nakai. The 1H and 13C NMR chemical shifts of the compound were completely assigned using a combination of 1D(1H, 13C NMR, NOE and DEPT) and 2D NMR(1H-1H COSY,HSQC, HMBC and NOESY) techniques and by referring to 1H and 13C NMR spectra of icariside Ⅱ, 2″-rhamnosyl icariside Ⅱ and icariin. The structure of the compound was determined to be 4′-Methylether, 3-O-[3-one-β-L-quinovosyl-(1→2)-α-L-rhamnopyranoside], 5, 7-dihydroxy-2-(4-hydroxyphenyl)-8-(3-methyl-2-butenyl)-4H-1-benzopyran-4-one.

Key words: NMR, assignment, 2D NMR, 3′″-carbonyl-2″-β-L-quinovosyl icariside Ⅱ
