Iridoid glucosides from Veronica hederifolia.
A new iridoid glucoside, urphoside A, and six known iridoid glucosides, pikuroside, aucubin, veronicoside, catalposide, amphicoside, and verminoside, were isolated from Veronica hederifolia together with a known megastigmane glucoside, 3-hydroxy-5,6-epoxy-beta-ionol-9-O-beta-D-glucopyranoside, and a hexitol, dulcitol. The structures of the isolated compounds were established by the extensive 1D...
متن کاملIridoid glucosides from Thunbergia laurifolia.
Two iridoid glucosides, 8-epi-grandifloric acid and 3'-O-beta-glucopyranosyl-stilbericoside, were isolated from the aerial part of Thunbergia laurifolia along with seven known compounds, benzyl beta-glucopyranoside, benzyl beta-(2'-O-beta-glucopyranosyl) glucopyranoside, grandifloric acid, (E)-2-hexenyl beta-glucopyranoside, hexanol beta-glucopyranoside, 6-C-glucopyranosylapigenin and 6,8-di-C-...
متن کاملFour new iridoid glucosides containing the furan ring from the fruit of Cornus officinalis.
Four new and rare iridoid glucosides, cornusfuroside A-D (1-4), containing the furan ring were identified from water extract of the fruit of Cornus officinalis. These new chemical structures were determined through extensive spectroscopic analysis, including 1D and 2D NMR, IR, HRESIMS, experimental and calculated electronic circular dichroism (ECD). Notably, this study is the first report on th...
متن کاملAragoside and iridoid glucosides from Aragoa cundinamarcensis.
From the water-soluble part of an extract of Aragoa cundinamarcensis were isolated seven iridoid glucosides, namely aucubin, catalpol, rehmannioside D, globularin, gardoside methyl ester, epiloganin and mussaenoside. The main glycoside isolated, however, was a new caffeoyl phenylethanoid triglycoside, named aragoside, containing two beta-gluco- and one alpha-arabinopyranosyl moieties which cons...
متن کاملMegastigmane and iridoid glucosides from Clerodendrum inerme.
From the aerial parts of Clerodendrum inerme, two megastigmane glucosides (sammangaosides A and B) and a iridoid glucoside (sammangaoside C) were isolated together with 15 known compounds. The structural elucidations were based on analyses of physical and spectroscopic data.
