Acylated iridoid glycosides with hyaluronidase inhibitory activity from the rhizomes of Picrorhiza kurroa Royle ex Benth.

Phytochemistry, 2019
Seven new acylated iridoid glycosides, picrorhizaosides A-G (1-7), were isolated from the methanol extract of the rhizomes of Picrorhiza kurroa Royle ex Benth. (Plantaginaceae), in addition to six known iridoid glycosides (8-13).

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.

Iridoid Glycosides from Hedyotis corymbosa

Helvetica Chimica Acta, 2007
AbstractThree new iridoid glycosides, hedycorysides A–C (1–3, resp.), were isolated from the whole plant of Hedyotis corymbosa (Linn.) Lam., along with four known compounds. Their structures were elucidated by extensive 1D‐ and 2D‐NMR analysis, as well as by HR‐ESI‐MS experiments. The three new compounds are the first benzoylated geniposide derivatives

Iridoid Glycosides from Barleria lupulina

Journal of Natural Products, 2015
Phytochemical investigation of an extract of the aerial part of Barleria lupulina resulted in the identification of four new iridoid glycosides (1-4), together with 14 known analogues (5-18). The structures of 1-4 were determined through 1D and 2D NMR spectroscopic data analysis, HRMS, and acid hydrolysis. This is the first report of iridoid glycosides

Iridoid and phenolic glycosides from Morinda coreia

Phytochemistry, 2002
From the leaves and branches of Morinda coreia, six compounds [yopaaosides A-C, 10-O-acetylmonotropein, 6-O-acetylscandoside and 3,4,5-trimethoxyphenyl 1-O-beta-apiofuranosyl (1"-->6')-beta-glucopyranoside] have been isolated together with five known compounds. Structural elucidations were based on analyses of physical and spectroscopic data.

Establishment of adventitious root cultures of Allamanda cathartica L. for the production of iridoid glycosides and its identification using HPTLC MS

Industrial crops and products (Print), 2018
This study attempts to develop a reproducible protocol for in vitro adventitious root regeneration for enhanced biomass production from nodal segments of Allamanda cathartica L., which may be of use as an alternative source for production of iridoid ...
