An 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 کاملChlorine-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.
متن کاملAn Iridoid Glucoside and the Related Aglycones from Cornus florida
A new iridoid glucoside, cornusoside A (1), and four new natural product iridoid aglycones, cornolactones A-D (2-5), together with 10 known compounds were isolated from the leaves of Cornus florida. The structures of compounds 1-5 were established by interpretation of their spectroscopic data. Cornolactone B (3) is the first natural cis-fused tricyclic dilactone iridoid containing both a five- ...
متن کاملA tetrahydroisoquinoline-monoterpene glucoside and an iridoid glucoside from Alangium kurzii.
From the leaves of Alangium kurzii, a new tetrahydroisoquinoline-monoterpene glucoside, 6-O-methyl-N-deacetylipecosidic acid and a new iridoid glucoside, 10-O-benzoyladoxosidic acid, were isolated along with alangiside, demethylalangiside, 6''-O-beta-D-glucosylhenryoside, uridine and four known flavonoid glycosides. The structures of new glucosides were determined on the basis of spectroscopic ...
متن کاملSesinoside, 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.
