Two new iridoid glycosides from Callicarpa nudiflora

Journal of Asian natural products research, 2020
Two new iridoid glycosides, callicoside E (1) and callicoside F (2), were isolated from the leaves of Callicarpa nudiflora. Their structures were established by one- and two-dimensional NMR spectroscopy and mass spectrometry.

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;

Comparative anti-arthritic investigation of iridoid glycosides and crocetin derivatives from Gardenia jasminoides Ellis in Freund's complete adjuvant-induced arthritis in rats.

Phytomedicine, 2019
BACKGROUND Discovering novel compounds with higher activities is a key aim of natural products research. Gardenia jasminoides Ellis is a herb with anti-inflammatory properties. Iridoid glycosides (mainly geniposide) and crocetin derivatives (crocins) are

THE OCCURRENCE OF IRIDOID GLYCOSIDES IN THE VERBENACEAE*

Acta Botanica Neerlandica, 1975
SUMMARY 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, 1972
SUMMARY 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, 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.
