Abstract
A lignan glycoside, syringaresinol-4',4"-O-di-B-D-glucopyranoside (1) (=liriodendrin), 4 phenylethanoid glycosides, acteoside (2), isoacteoside (3), forsythoside B (4) and leucosceptoside B (5), a caffeic acid ester, chlorogenic acid (6) and 2 iridoid glucosides, lamiide (7) and auroside (8). were isolated from the methanolic extracts of the aerial parts of Phlomis kotschyana, along with an acetophenone glycoside, 4-hydroxyacetophenone 4-O-[6'-O-beta-D-apiofuranosyl]-beta-D-glucopyranoside (9). The Structures of the isolated compounds were identified on the basis of spectroscopic (UV, IR, 1D- and 2D-NMR, and FAB-MS) methods.
