Iridoid Glycosides of Leonurus persicus
Journal of Natural Products, 1999Two 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, 1996The 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 saccatum
Chemistry of Natural Compounds, 1983An 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;

THE OCCURRENCE OF IRIDOID GLYCOSIDES IN THE VERBENACEAE*
Acta Botanica Neerlandica, 1975SUMMARY 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 ...

THE OCCURRENCE OF IRIDOID GLYCOSIDES IN THE LABIATAE
Acta Botanica Neerlandica, 1972SUMMARY Iridoid glycosides were found in many species of the following taxa of the Labiatae: Prostantheroideae, Ajugoideae, Prasioideae, Scutellarioideae, Stachydoideae-Marrubieae and St.-Stachydeae. Iridoid glycosides were not found in any species of the following subfamilies: Rosmarinoideae, Ocimoideae, Lavanduloideae, and Stachydoideae (except ...

Iridoid glycosides and glycosidic constituents from Eriophyton wallichii Benth
Phytochemistry, 2011C₉-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.
