Iridoid glycosides and glycosidic constituents from Eriophyton wallichii Benth

Phytochemistry, 2011
C₉-iridoid glycosides, wallichiisides A-C, and four dimers, wallichiisides D-G, together with 13 known glycosidic compounds, were isolated from whole plants of Eriophyton wallichii Benth. Their structures were elucidated by spectroscopic methods and comparison with literature values.

Iridoid glycoside biosynthesis in Penstemon secundiflorus. Another H-5, H-9 trans-iridoid glycoside

Phytochemistry, 1998
Isolation and characterization of the new iridoid 10-hydroxy-(5 alpha H)-6-epidihydrocornin from Penstemon secundiflorus (Scrophulariaceae) is described. In biosynthetic experiments, deoxyloganic acid was incorporated into the trans-fused iridoid glycosides (5 alpha H)-6-epidihydrocornin and 10-hydroxy-(5 alpha H)-6-epidihydrocornin in P. secundiflorus.

Iridoid Glycosides from Hedyotis corymbosa

Helvetica Chimica Acta, 2007
AbstractThree new iridoid glycosides, hedycorysides A–C (1–3, resp.), were isolated from the whole plant of Hedyotis corymbosa (Linn.) Lam., along with four known compounds. Their structures were elucidated by extensive 1D‐ and 2D‐NMR analysis, as well as by HR‐ESI‐MS experiments. The three new compounds are the first benzoylated geniposide derivatives

THE OCCURRENCE OF IRIDOID GLYCOSIDES IN THE VERBENACEAE*

Acta Botanica Neerlandica, 1975
SUMMARY Many Verbenaceae contain one or more iridoid glycosides, several of which are still unidentified. Some of the latter were characterized by their specific optical rotations and Rf-values on paper chromatograms. Iridoid glycosides were found in the tribes Viticeae and Clerodendreae (Viticoideae), Physopsideae (Chloanthoideae), Citharexyleae ...

Iridoid Glycosides from Barleria lupulina

Journal of Natural Products, 2015
Phytochemical investigation of an extract of the aerial part of Barleria lupulina resulted in the identification of four new iridoid glycosides (1-4), together with 14 known analogues (5-18). The structures of 1-4 were determined through 1D and 2D NMR spectroscopic data analysis, HRMS, and acid hydrolysis. This is the first report of iridoid glycosides

Iridoid and phenolic glycosides from Morinda coreia

Phytochemistry, 2002
From the leaves and branches of Morinda coreia, six compounds [yopaaosides A-C, 10-O-acetylmonotropein, 6-O-acetylscandoside and 3,4,5-trimethoxyphenyl 1-O-beta-apiofuranosyl (1"-->6')-beta-glucopyranoside] have been isolated together with five known compounds. Structural elucidations were based on analyses of physical and spectroscopic data.

Iridoid Glycosides from Tabebuia avellanedae

Chemistry & Biodiversity, 2016
Five novel iridoid glycosides, avellanedaesides A‐E (1 – 5) were isolated from the H2O extract of Tabebuia avellanedae. Their structures were determined on the basis of NMR and MS analysis. Isolated compounds suppressed inflammatory cytokine, tumor‐necrosis factor‐α and interleukin‐1β production in cultured human myeloma THP‐1 cells co‐stimulated with ...

THE OCCURRENCE OF IRIDOID GLYCOSIDES IN THE SCROPHULARIACEAE

Acta Botanica Neerlandica, 1970
SUMMARY A study was made of the occurrence of iridoid glycosides (giving a colour reaction with anisidine) in the Scrophulariaceae. Aucuboside, catalpol and antirrhinoside were found in many species: in addition some hitherto unknown, presumably iridoid glycosides were found.

A new iridoid glycoside from Linaria genestifolia

Fitoterapia, 2006
A new iridoid glycoside named genestifolioside (1) was isolated from the ethanol extract of Linaria genestifolia. Its structure was defined by spectral analysis.
