title: 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.
