title: Iridoids from Phlomis aurea Decne growing in Egypt.
abstract: A new iridoid gentiobioside (4, assigned the name phlomiside) was isolated from the leaves of Phlomis aurea growing in Egypt, in addition to auroside (1), lamiide (2), 8-epi-loganin (3), forsythoside B (5), quercetin-3-O-beta-D-glucopyranoside (6) and kaempferol-3-O-beta-D-glucopyranosyl-(1-6)-beta-D-glucopyranoside (7). Structures of these compounds were elucidated by conventional methods of analysis as well as by different spectroscopic techniques.
