In a chemosystematic investigation of tribe Veroniceae (Plantaginaceae), representatives of Camptoloma, Sibthorpia, Veronica subg. Pentasepalae and subg. Hebe, Veronicastrum, Wulfenia, and the related Ellisiophyllum and Globularia were examined for non-flavonoid glycosides. From the 14 species studied, 28 different iridoid glucosides and 10 caffeoyl phenylethanoid glucosides (CPGs), as well as salidroside and arbutin were isolated and characterized by NMR; of these, five compounds were… Expand
Unusual iridoid glycosides in Veronica sects. Hebe and Labiatoides
TLDR
In a chemosystematic investigation of three Southern hemisphere species of Veronica, the water-soluble constituents were isolated and identified by spectroscopic methods, three unusual substituted benzoyl esters of aucubin (derwentiosides A–C) were obtained from V. derwentiana and V. catarractae in addition to other iridoids common to the genus.

Iridoid and phenylethanoid glycosides in the New Zealand sun hebes (Veronica; Plantaginaceae).
TLDR
The esters of cinnamic acid derivatives with iridoid and phenylethanoid glycosides and an unusually high concentration of verminoside were found to be the most distinctive chemotaxonomic characters of the sun hebes. Expand
Iridoid glucosides in the genus Veronica (Plantaginaceae) from New Zealand.
TLDR
The pattern of the structural features of the iridoid glucosides is overlaid onto the latest molecular phylogenetic framework of Veronica sects, and discussed in the context of evolutionary trends. Expand
Iridoid and phenylethanoid glucosides from Veronica lavaudiana.
TLDR
From an extract of Veronica (sect. Hebe) lavaudiana, mannitol and isolated 11 iridoid glucosides, the carbohydrate ester hebitol II, and four phenylethanoid glycoside esters are identified, demonstrating that the structures of the known glycosides globularitol and hebitols I and II should be revised.

Iridoid glycosides of the tribe Antirrhineae
TLDR
Despite the different degrees of study of the tribe representatives, it can conclude the presence of antirrhinoside as a marker of this group of plants. Expand
Chemotaxonomic interest of iridoids isolated from a Malagasy species: Perichlaena richardii
TLDR
The structures of the isolated compounds were established using different spectroscopic methods including extensive 1D and 2D-NMR and mass spectrometry, and the activity of verminoside, rutin and caffeic acid on enzymes involved in inflammation, cyclooxygenase and lipoxygenases, was determined on human peripheral venous blood samples.

Iridoid glucosides of Paederota bonarota and the relationships between Paederota and Veronica
In a chemical investigation of the water-soluble compounds in Paederota bonarota, five known iridoid glucosides were isolated together with a compound with an 8,9-double bond, namely bonarotosideExpand
Chemical markers in Veronica sect. Hebe. III
TLDR
It is concluded that carbohydrate esters are common in sect. Expand
Chemical Traits of Hemiparasitism in Odontites luteus
TLDR
The study of the monoterpene glycosides content of Odontites luteus has shown the presence of a total of fifteen iridoid glucosides which are perfectly on‐line with both the biogenetic pathway for iridoids biosynthesis in Lamiales and the current botanical classification of the species. Expand
A new phenylethanoid triglycoside in Veronica beccabunga L
Besides the expected iridoid glucosides aucubin and catalpol as well as three known esters of the latter, Veronica beccabunga (brooklime) was shown to contain five carboxylated iridoid glucosides,Expand

TLDR
The close relationship between Plantago and Veronica suggested by chloroplast DNA sequence analysis could be corroborated by the common occurrence of the rare 8,9-unsaturated iridoids in these two genera. Expand

Veronica: Iridoids and cornoside as chemosystematic markers
TLDR
Using the recent expansion and reclassification of the genus based on DNA-sequence results as the model, it is found that the genus is rather homogeneous with regard to the distribution of iridoid glucosides, aucubin and/or catalpol as well as 6-O-esters ofCatalpol being universally present in 10 of the 12 subgenera for which data exist.

Chemotaxonomy and evolution of Plantago L.
TLDR
In investigations of the genus Plantago L. (Plantaginaceae), sixteen species were investigated with respect to water-soluble glycosides, finding an abundance of iridoid glucosides present in one of the two groups within subgenus Coronopus sectionCoronopus, while the other group lacks iridoids, supporting a subdivision of this section.

A chemosystematic study of Veronica: Iridoid glucosides
TLDR
Loganin has been identified in five species, this being the first time that this compound has been found in the Scrophulariaceae, and is accompanied by unidentified loganin esters in the same five species. Expand

TLDR
It could be concluded that the two species are very close in the phylogeny, and both can be used as the same traditional drug. Expand
Iridoid glucosides of Paederota lutea and the relationships between Paederota and Veronica.
TLDR
It is shown that Veronica, Paederota, Picrorhiza and Veronicastrum are all characterized by containing 6-O-esters of catalpol, and some less closely related taxa namely: Lagotis, Wulfenia, Plantago, Aragoa and Globularia instead contain 10-O -esters ofCatalpol or aucubin. Expand

TLDR
The present findings support the results from a recently published molecular phylogenetic study of plastid and nuclear ribosomal DNA sequences, where Aragoa was found to be the closest relative to Plantago so far discovered. Expand
