Abstract: Five iridoid glycosides, lamiide, ipolamiide, ipolamiidoside, 6\beta-hydroxyipolamiide, and 5-hydroxy-8-epi-loganin; 5 flavonoid glycosides, apigenin 7-O-\beta-glucopyranoside, luteolin 5-O-\beta- glucopyranoside, isorhamnetin 3-O-rutinoside, quercetin 3-O-rutinoside, and apigenin 7-O-(6''-O-trans-p-coumaroyl) \beta-glucopyranoside; and a phenylethanoid glycoside, acteoside (= verbascoside), were isolated from the aerial parts of Wiedemannia orientalis (Lamiaceae). Their structures were identified using spectral methods (UV, 1D- and 2D-NMR, and EI-MS).

Keywords: Lamiaceae, Wiedemannia orientalis, iridoid glycoside, flavonoid glycoside, phenylethanoid glycoside
