Sesinoside, a new iridoid glucoside from sesame (Sesamum indicum) seedlings.
A new iridoid glucoside, sesinoside (1), was isolated from the seedlings of Sesamum indicum. The structure of 1 was elucidated by spectroscopic analyses and by methanolysis of 1, which produced the known compounds, phlorigidosides C (2) and (6Z)-foliamenthic acid methyl ester (3). This is the first report of an iridoid glucoside with 3.
متن کاملAn iridoid glucoside dimer and a non-glycosidic iridoid from the leaves of Lasianthus wallichii.
A new iridoid glucoside dimer (1) and a non-glycosidic iridoid (2) was isolated together with the known compounds, asperuloside (3), paederoside (4), daphylloside (5), citroside A (6) and benzyl 6-O-alpha-L-rhamnopyranosyl-beta-D-glucopyranoside (7), from the leaves of Lasianthus wallichii. The structures of the new compounds were elucidated by spectroscopic and chemical evidence.
متن کاملScyphiphin C, a new iridoid from Scyphiphora hydrophyllacea.
Chemical investigation of the ethanol extract of the aerial parts of Scyphiphora hydrophyllacea Gaertn.collected in Hainan Province of China resulted in the isolation of a new iridoid, scyphiphin C (1) and a known iridoid glycoside, shanzhiside methyl ester (2). Their structures were elucidated by a study of their physical and spectral data.

15 صفحه اولChlorine-containing iridoid and iridoid glucoside, and other glucosides from leaves of Myoporum bontioides.
Sixteen compounds were isolated from the MeOH extract of leaves of Myoporum bontioides. The five compounds hitherto unknown, were elucidated to be a chlorine-containing iridoid, named myopochlorin, and an iridoid glucoside, an acylated iridoid glucoside, a linear acetogenin glucoside, and an acyclic monoterpene glucoside, named myobontiosides A-D, respectively, by means of spectroscopic analyses.
