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 Veronica pectinata var. glandulosa.
A new highly oxygenated iridoid glucoside, urphoside B (1) was isolated from the Veronica pectinata var. glandulosa together with seven known iridoid glucosides, aucubin, catalpol, veronicoside, catalposide, verproside, amphicoside and 6-O-veratroyl catalpol. The planar as well as the stereo structures of the isolated compounds were determined by means of extensive 1D- and 2D-NMR spectroscopy a...
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 کاملIridoid glucosides of Paederota bonarota and the relationships between Paederota and Veronica
In a chemical investigation of the water soluble compounds in Paederota bonarota five known iridoid glucosides were isolated together with a compound with an 8,9-double bond, namely bonarotoside (10-O-benzoyl arborescosidic acid). The known iridoid glucosides were aucubin, catalpol and the 6-O-esters of catalpol: verproside, catalposide, amphicoside and veronicoside, compounds that are characte...
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...
