Non-glycosidic iridoids from Cymbaria mongolica
Phytochemistry, 2002Six non-glycosidic iridoids, i.e. (1R,4S,4aS,7S,7aS)-7-hydroxyl-4-hydroxy- methyl-7-methyl-1-methoxyl-1,4,4a,7a-tetrahydrocyclopenta[e]pyran-3-one (1), (1S,4R,4aS,7S,7aS)-7-hydroxyl-4-hydroxymethyl-7-methyl-1-methoxyl-1,4,4a,7a-tetrahydrocyclopenta[e]pyran-3-one (2), (1R,4R,4aS,7S,7aS)-7-hydroxyl-4-hydroxy-methyl-7-methyl-1-methoxyl-1,4,4a,7a ...

Cardioactive iridoid glycosides from Eremophila species
Phytomedicine, 1997Four 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.

THE OCCURRENCE OF IRIDOID GLYCOSIDES IN THE SCROPHULARIACEAE
Acta Botanica Neerlandica, 1970SUMMARY 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, 2010Three 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, 1991A 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 ...

Iridoid Glycosides from Tabebuia avellanedae
Chemistry & Biodiversity, 2016Five 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 ...

Iridoid glycosides from Barleria trispinosa
Natural Product Research, 2009A new iridoid glycoside and three known iridoid glycosides were isolated from the aerial parts of Barleria trispinosa. The structure of the new compound was determined as 6-alpha-L-rhamnopyranosyl-8-O-acetylshanzihiside methyl ester. The known compounds were identified as 6,8-O,O-diacetylshanhiside methyl ester (acetyl barlerin), 8-O-acetylshanzhiside ...
