Chemical Profiling and Biological Activity of Copaiba Oil‐Resin Samples and Development of HPLC‐DAD Method for the Analysis of β‐Caryophyllene

Biomedical Chromatography, Volume 40, Issue 5, May 2026.
ABSTRACT The Copaifera species are traditionally used for their anti‐inflammatory, antiseptic and healing properties. The objective of this study was to compare the chromatographic profiles of seven samples of copaiba oil‐resin with respect to chromatographic and physicochemical properties and to evaluate their biological activities.

Manganese Porphyrin‐Catalyzed One‐Pot Oxidation of Lupeol: Efficient Conversion of Its Terminal Alkene Into Carboxylic Acids

Chemistry &Biodiversity, Volume 23, Issue 5, May 2026.
Manganese porphyrin catalyst enables green PhI(OAc)2 oxidation of lupeol in ethyl acetate, achieving 94% conversion and the formation of eight products, including selective C20 olefin transformations and one‐pot conversion of the isopropenyl group to carboxylic acids, all without the need of C3‐OH protection step.

Wernicke’s Encephalopathy Secondary to Hyperemesis Gravidarum in Pregnancy: A Case Report

Clinical Case Reports, Volume 14, Issue 5, May 2026.
ABSTRACT Wernicke's Encephalopathy, although classically associated with chronic alcoholism, can also occur during pregnancy as a complication of hyperemesis gravidarum and is often underdiagnosed. We report a case of a 34‐year‐old pregnant woman at 16 weeks of gestation who presented with prolonged vomiting, altered mental status, nystagmus, and gait ...

Beyond the Solid Solution: Ordered Enantiomerically Unbalanced Packing in Surface‐Confined Tetrahelicene Monolayers

Chirality, Volume 38, Issue 5, May 2026.
Racemic dicyanotetrahelicene exhibits coverage‐dependent self‐assembly on Ag(111), transitioning from spontaneous chiral resolution at low coverage to a dense mixed phase at monolayer saturation. While submonolayer deposition produces extended homochiral domains, full coverage yields a compact, long‐range ordered lattice with an enantiomerically ...

Purification of α,β‐Unsaturated Carboxylic Acids as Their Potassium Carboxylate Salts Using Dry Column Vacuum Chromatography

Chemistry–Methods, Volume 6, Issue 5, May 2026.
Isolation of α,β‐unsaturated carboxylic acids from mixtures containing phosphine oxides (formed in Wittig‐type reactions) using standard procedures resulted in unsatisfactory outcomes in terms of product yield and/or purity. A new method involving purification of the products as their carboxylate salts using dry column vacuum chromatography enabled the
