Drug Testing and Analysis, EarlyView.A LC–MS/MS method has been validated for analysis of semi‐synthetic cannabinoids (SSC) and selected phytocannabinoids in seizures. Further SSC‐derivatives were implemented into the method for qualitative detection. The methodology was applied to a sample collective (n = 80) including cannabis flowers, resins, edibles and vape liquids.

Drug Testing and Analysis, EarlyView.This study developed a comprehensive metabolomics workflow using GC‐HRMS and LC‐HRMS/MS and analyzed 35 CBD‐type cannabis flowers grown under varying conditions. Key discriminative compounds enabled classification by chemical phenotype and cultivation environment. The results showed that environmental factors influence chemical profiles, supporting the

Polyoxotungstate‐Stabilized Gold Nanoparticles: How to Transfer from an Aqueous Suspension to CH3CN
European Journal of Inorganic Chemistry, EarlyView.Available methods inspired by the literature for preparing stable suspensions of gold nanoparticles stabilized by polyoxometalates (POMs@AuNPs) in CH3CN, a solvent commonly used in oxidation reactions, are compared. The evaluation criteria used are the ease of obtaining and the stability of the POM@AuNPs suspensions, as well as the reproducibility of ...

European Journal of Lipid Science and Technology, EarlyView.The latex of Hevea brasiliensis is rich in furan fatty acid (FuFA) esterified in both neutral and polar lipids. Bio‐based solvents to extract FuFA from ammonia‐stabilized latex was tested. Ethyl acetate worked best, especially with low‐ammonia content. Isopropanol was a good alternative. Lipases could also help to efficiently release FuFA. The findings

Food Chemistry International, EarlyView.Product identification of flavonoids under weak base conditions and mechanism analysis of dimer formation by the oxidative assembly of quercetin and morin, respectively. ABSTRACT Flavonoids are susceptible to autoxidation in aqueous solutions, which is largely dependent on pH, generating various free radicals and oxidation products. Quercetin and morin
