Chemical Characterization, Antioxidant and Enzyme‐Inhibitory Activities of Different Extracts from Three Phlomis Species

open access: yesChemistryOpen, EarlyView.
The tested Phlomis species are a rich source of bioactive molecules with potential therapeutic applications, and selecting appropriate extraction solvents is crucial for achieving the targeted biological activity. Phlomis species (family Lamiaceae) are highly valued as food and herbal medicine.

One‐Step Aqueous Synthesis of Glycosyl Pyridinium Salts, Electrochemical Study, and Assessment of Utility as Precursors of Glycosyl Radicals Using Photoredox Catalysis

open access: yesChemistryOpen, EarlyView.
Unprotected glycosyl pyridinium salts may be accessed in a single step from the corresponding unprotected sugar in aqueous solution. Whilst meta‐ and para‐substitution is well tolerated, ortho substitution of the N‐heterocycle inhibits product formation. Electrochemical studies revealed reduction potentials in the range of −0.9 to −1.4 V.

Quality Control Strategies for Differentiation of Kalanchoe Species

open access: yesPhytochemical Analysis, EarlyView.
ABSTRACT Kalanchoe species products are commercially available in local markets and by internationally accessible online retailers and may exhibit quality issues because of misidentification from similar common names and anatomical similarities among related species used as feedstock. This study proposes an approach using UPLC‐MS/MSE and HPTLC, coupled

Differential gene expression in Chorthippus parallelus (Zetterstedt, 1821) (Orthoptera: Acrididae: Gomphocerinae) induced by Wolbachia infection

open access: yesInsect Science, EarlyView.
Distinct lineages of the grasshopper Chorthippus parallelus (Orthoptera: Acrididae) form a well‐known hybrid zone (HZ) in the Pyrenees mountain range; the Iberian endemism C. p. erythropus (Cpe) and the subspecies C. p. parallelus, (Cpp) widely distributed throughout the rest of Europe. Both subspecies differ in diverse traits, including the strains of

Multi‐omics reveal the gut microbiota‐mediated severe foraging environment adaption of small wild ruminants in the Three‐River‐Source National Park, China

open access: yesIntegrative Zoology, EarlyView.
This research reveals the gut microbiota‐mediated severe foraging environment adaptation of wild small ruminants in the Three‐River‐Source National Park. Unlike Tibetan sheep (TS), blue sheep (PN and Tibetan antelope (TA) often grazed low‐quality herbage in a wildness environment, and the higher microbial diversity and resilient network characteristics
