摘要
对3′″-羰基-2″-β-L-奎诺糖基淫羊藿次苷Ⅱ(3′″-carbonyl-2″-β-L-quinovosy licarisideⅡ),进行了1H和13C MNR检测,参考2″-O-鼠李糖基淫羊藿次苷Ⅱ(2″-O-rhamnosy licarisid Ⅱ)、淫羊藿次苷Ⅱ(icarisid Ⅱ)和淫羊藿苷(icariin)的1H、13C NMR数据,通过DEPT和1H-1H COSY、HSQC、HMBC等2D NMR技术对该化合物所有的1H和13C NMR信号进行了全归属和详细解析.
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 ^13 C NMR spectra of icariside Ⅱ , 2＂-rh- amnosyl 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.
