Studies of iridoid glycosides using liquid chromatography/electrospray ionization tandem mass spectrometry

open access: yes, 2007
Fragmentation pathways of five iridoid glycosides have been studied by using electrospray ionization multi-stage tandem mass spectrometry (ESI-MSn). The first-stage MS data of the five iridoid glycosides were compared.

Thiol addition to protected allyl glycosides: an improved method for the preparation of spacer-arm glycosides [PDF]

open access: yes, 1997
A useful method for the preparation of differently functionalized sulfide spacer-arm glycosides is presented. Several protected allyl glycosides were variously elongated via a radical addition reaction with pentanethiol, methyl 3-mercaptopropionate, or 2-

Integration of Nutrition and Organic Agriculture Framework in Managing Gastrointestinal Nematodes in Ruminants

open access: yesAnimal Research and One Health, EarlyView.
Gastrointestinal nematode infections damage the gastrointestinal epithelial tissues of ruminants, affecting nutrient utilization and overall production performance. This review outlines host‐gastrointestinal nematode interactions and discusses integrated control strategies, including nutritional supplementation, grazing management, vaccines, and ...

Two new xanthone glycosides from Swertia tetraptera

open access: yes, 2001
Two new xanthone glycosides, tetraswerosides A and B, were isolated from the whole plant of Swertia tertraptera. Their structures were determined as 3-O-beta -D-glucopyranosyl-1-hydroxy-4,7-dimethoxyxanthone and 3-O-[beta -D-xylopyranosyl-(1-->6)-beta -D-

2-Deoxy-2-iodo-α-mannopyranosyl and -talopyranosyl Acetates:  Highly Stereoselective Glycosyl Donors for the Synthesis of 2-Deoxy-α-glycosides

open access: yes, 2016
TMS-OTf- or TBS-OTf-promoted glycosidation reactions of 2-deoxy-2-iodo-α-mannopyranosyl acetates 8−10 and the 2-deoxy-2-iodo-α-talopyranosyl acetate 11 provide the corresponding 2-deoxy-2-iodo-α-pyranosides, precursors to 2-deoxy-α-glycosides, as the ...

Synergistic Enhancement of Antioxidant Activity in Arbutus unedo Leaf Extract by Biological Fluids: Implications for Functional and Nutraceutical Applications

open access: yesBiotechnology and Applied Biochemistry, EarlyView.
ABSTRACT This study examined the effect of biological fluids (saliva, blood plasma, and urine) on the antioxidant capacity of an aqueous extract derived from Arbutus unedo leaves. The extract displayed a concentration‐dependent reducing activity in the ferric reducing power assay (IC50 = 292 ± 7.54 µg/mL) and phosphomolybdenum assays (IC50 = 461.67 ± 4.

Bioeconomy, sustainability, and digital technologies in Haematococcus lacustris biomass and astaxanthin production: advances and outlook

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract Astaxanthin is a carotenoid with strong antioxidant properties, used in research on cancer treatment, ocular injuries, and neurological disorders. When produced by the microalgae Haematococcus lacustris, its antioxidant potential is even higher than that of the synthetic molecule, making it particularly attractive for pharmaceutical and ...
