Acylated iridoid glucosides from Veronica anagallis-aquatica

Bioassay-guided isolation of iridoid glucosides with antinociceptive and anti-inflammatory activities from Veronica anagallis-aquatica L.

“…Successive application of RP-MPLC and Si-gel column chromatography techniques have led to the isolation of three new (1-3) and four known iridoid glucosides (4), in addition to a known phenylethanoid glycoside (8). Their structures were determined as aquaticoside A (1), aquaticoside B (2), aquaticoside C (3), veronicoside (4), catalposide (5), verproside (6), verminoside (7) and martynoside (8) by extensive 1D and 2D-NMR spectroscopy (Harput et al, 2004) (Fig. 1).…”

“…B was carried out by spectral techniques; UV, 1D and 2D NMR ( 1 H, 13 C NMR) and mass spectroscopy (HR-ESI-FTMS) and detailed data were recently published elsewhere (Harput et al, 2004). The structures of compounds 1-8 were as follows ( Fig.…”

Iridoid glucoside, (3R)-oct-1-en-3-ol glycosides, and phenylethanoid from the aerial parts of Caryopteris incana

“…In the 13 C-NMR spectrum, nine and two signals were assignable to a caffeoyl moiety and an acetyl group, respectively (Table 1). Six signals were assigned to 6-O-acylated glucopyranose [11], the remaining nine signals together with the acetyl signals being expected for the aglycone of 8-O-acetylharpagide (1) [4] ( Table 1). From this evidence, the structure of 3 was elucidated to be 6 0 -O-caffeoyl-8-Oacetylharpagide.…”

“…Various types of chromatography were used to isolate eleven compounds of interest from the 1-BuOH-soluble fraction of a MeOH extract of C. incana, specifically three iridoid glucoside derivatives (1)(2)(3), three (3R)-oct-1-en-3-ol (matsutake alcohol) glycosides (4)(5)(6), and five phenolic glycosides (7)(8)(9)(10)(11) (Fig. 1).…”

Influence of Plantaginaceae species onE. coli K12growthin vitro: Possible relation to phytochemical properties

“…Among those plants are Plantago and Veronica species, both traditionally used in folk medicine (Harput et al, 2004;Samuelsen, 2000). Recent studies have revealed phylogenetic proximity between these genera (Albach et al, 2005).…”
