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.

Iridoid Glycosides fromSaprosma ternatum

Planta Medica, 2010
Three new iridoid glycosides, epiasperuloside (1), epipaederosidic acid (2), and epipaederoside (3), together with 7 known compounds, were isolated from the 85% ethanol extract of the leaves of Saprosma ternatum Hook. f. Their structures were determined by application of spectroscopic (NMR, MS) and chemical methodologies.

Phenylpropanoid and iridoid glycosides from Pedicularis striata

Phytochemistry, 1991
A new phenylpropanoid glycoside, pedicularioside A, and five known glycosides, acteoside, isoacteoside, decaffeoylacteoside, echinacoside and 8-acetylharpagide, were isolated from whole plants of Pedicularis striata. On the basis of spectral and chemical evidence, pedicularioside A was shown to be 1'-O-beta-D-(3,4-dihydroxy-beta-phenyl)-ethyl-4'-O ...

Cardioactive iridoid glycosides from Eremophila species

Phytomedicine, 1997
Four iridoid glycosides isolated from different species of Eremophila (Myoporaceae) were tested for their effects on the Langendorff rat heart. Melampyroside (1), verminoside (2), ferruloylajugol (3) and catalpol (4) all significantly decreased contractile force in the isolated rat heart test.
