从油茶叶提取物中分离得到两种高纯度活性化合物,通过~1H-NMR、~(13)C-NMR、H-H COSY、DEPT、HSQC以及HMBC等核磁共振方法分析其结构,最终鉴定其为二氢白藜芦醇(化合物1)和1-(3',5'二甲氧基)苯基2- O-[4″吡喃葡萄糖基(6→1)-吡喃鼠李糖基]苯乙烷(化合物2)。对~1H-NMR和~(13)C-NMR信号分别进行全归属。化合物1是首次从油茶属植物中分离得到,化合物2是第2次从油茶叶中提取得到,且该物质的得率大大高于首次文献报道。

Two purified components from leaves of Camellia oleifera Abel, was extracted. With the spectrum of 1H-NMR, 13C-NMR, H-H COSY, DEPT-90, DEPT-135, HSQC and HMBC, they were analysized and identified. The two compounds are Dihydro-resveratrol (compound 1) and l-(3′, 5′-dimethoxy) phenyl-2-[4″-0-β-Z)-glucopyranosyl (6→1)-O-α-L-rhamnopyranosyl] phenylethane (compound 2). With 1H and 13C specturm, the number and affiliation of carbon and the hydrogen were elaborated. Compound 1 was first time achieved from family of Theaceae. Compound 2 was achi...
