Iridoid Glycosides of Leonurus persicus

Journal of Natural Products, 1999
Two new iridoid glucosides, 6-O-acetylajugol (1) and 7, 8-epoxy-8-epi-loganic acid (2), together with five known iridoid glucosides, galiridoside (3), ajugoside (4), 10-deoxygeniposidic acid (5), 7-deoxy-8-epi-loganic acid (6), and 8-O-acetylharpagide (7), have been isolated from the aerial parts of Leonurus persicus.

Iridoid glycosides from Thunbergia grandiflora

Phytochemistry, 1996
The novel iridoid glycosides, isounedoside and grandifloric acid, were isolated from Thunbergia grandiflora. Grandifloric acid contains C-10 as a carboxylic acid group, the presence of which was predicted by recent iridoid biosynthesis studies carried out within T. alata. Isounedoside contains a rare 6,7-epoxide functional group.

Iridoid glycosides ofVerbascum laxum

Chemistry of Natural Compounds, 1987
The epigeal part ofVerbascum laxum Filar, et Jav. has yielded in addition to the known sinuatol, a new iridoid glycoside — 6-0-(3″-0-p-coumaroyl-α-L-rhamnopyranosyl)aucubin (I), [α] D 20 −174.2±0.7° (c 1.4; MeOH).

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 glycosides ofVerbascum saccatum

Chemistry of Natural Compounds, 1983
An aqueous solution of a methanolic extract of the epigeal part ofVerbascum saccatum C. Koch (1.4 kg) was washed with organic solvents and chromatographed on columns of alumina, polyamide, and silica gel, leading to the isolation of 3.6 g of a new iridoid glycoside — saccatoside (I) — in the form of an amorphous substance with [α] D 20 −200±2.5° (c 0.2;

Three phenylethanoid glycosides and an iridoid glycoside from Picrorhiza scrophulariiflora

Phytochemistry, 1998
Three new phenylethanoid glycoside, named scrosides A-C and a new iridoid glycosides, named picroside IV, have been isolated from the underground parts of Picrorhiza scrophulariiflora, together with 11 known compounds. Their structures were elucidated by the means of 2D NMR spectroscopy and chemical methods.

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.
