摘要
摘要从苦参(Plicosepalu scurviflorus Benth)茎中分离得到萘糖苷曲维flor苷[1,5-二羟基-8-甲氧基萘萘-2- o -β- d -木pyranoside](3)和黄烷醇曲维florin[(+)-儿茶素-7- o -3″，4″-二羟基苯甲酸酯](4)，以及已知的两种黄酮类化合物(+)-儿茶素(1)和槲皮素(2)。利用二维核磁共振光谱对产自沙特阿拉伯的Loranthaceae植物及其化学结构进行了鉴定。
Curviflorside and curviflorin, new naphthalene glycoside and flavanol from Plicosepalus curviflorus
Abstract The naphthalene glycosidecurviflorside [1,5-dihydroxy-8-methoxynaphthalene-2-O-β-D-xylopyranoside] (3) and the flavanol curviflorin [(+)-catechin-7-O-3″,4″-dihydroxybenzoate] (4), along with two known flavonoids: (+)-catechin (1) and quercetin (2) were isolated from the shoots of Plicosepalu scurviflorus Benth. (Loranthaceae) growing in Saudi Arabia and the chemical structures were elucidated by 2D-NMR spectroscopy.
