Iridoid 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...

species. Similar findings have previously been reported for M. piperita (Bricout & Paupardin, 1975) and M. rotundifolia (Bricout et al., 1978). Many of the calluses accumulate only the early precursors of the monoterpenes (namely geraniol, linalol and lavandulol), but some species give rise to cultures that accumulate monoterpenes characteristic of the intact plant. For example, cell lines from...
متن کاملIridoid 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 کاملMonoterpene glucosides from Origanum syriacum.
From the aerial parts of Origanum syriacum, three new monoterpene glucosides thymoquinol 2,5-O-beta-diglucopyranoside (3), carvacrol 2-O-beta-glucopyranosyl-(1-->2)-beta-glucopyranoside (4) and p-menth-1-ene-3,4-diol 4-O-beta-glucopyranoside (5) together with two known monoterpene glucosides thymoquinol 2-O-beta-glucopyranoside (1), thymoquinol 5-O-beta-glucopyranoside (2) have been isolated. T...
