Phenylpropanoid and iridoid glycosides fromPedicularis lasiophrys

Phytochemistry, 1992
Two new compounds, pedicularioside E and F, were isolated from whole plants of Pedicularis lasiophrys, along with the four known compounds, verbascoside, cistanoside C, cistanoside D and 8-epiloganin. On the basis of spectral and chemical evidence, pedicularioside E and F were identified to be 1'-O-beta-D-(3-methoxy-4-hydroxy-beta-phenyl)-ethyl-6'-O ...

Protective effects of iridoid glycosides on acute colitis via inhibition of the inflammatory response mediated by the STAT3/NF-кB pathway.

International Immunopharmacology, 2020
Morroniside and loganin are iridoid glycosides extracted from Cornus officinalis, a plant species widely used in traditional Chinese medicine. However, the anti-inflammatory effects of morroniside and loganin in colitis are barely understood.

Iridoid Glycoside Constituents of Stachys lanata

Journal of Natural Products, 2008
From the aerial parts and roots of Stachys lanata, four new iridoid glucosides, stachysosides E-H (1-4), were isolated together with 30 known compounds. The structures and the stereo configurations of these new compounds were elucidated on the basis of the results of spectroscopic analysis. Compounds 1-4 are esters of monomelittoside.

Optimisation for simultaneous determination of iridoid glycosides and oligosaccharides in Radix Rehmannia by microwave assisted extraction and HILIC-UHPLC-TQ-MS/MS.

Phytochemical Analysis, 2020
Hydrophilic iridoid glycosides and oligosaccharides are the major active ingredients of Radix Rehmanniae. Analysis of oligosaccharides is a challenging task because they are highly hydrophilic, with similar chemical structures and absence of chromophore ...

Effect of temperature regulation on microbial community, volatile flavours, amino acid profiles, and iridoid glycosides during noni (Morinda citrifolia L.) fruit fermentation.

Food Chemistry
Noni fruit has an unpleasant flavour but is highly bioactive. Therefore, it is necessary to clarify the effect of temperature regulation on quality of fermented noni fruit. In the present study, the formation of flavours, amino acid profiles, and iridoid
