Comparative Phytochemical Profiles and Antioxidant Potential of Green and Variegated Morphotypes of Alternanthera bettzickiana Under Optimized Extraction Conditions

Food Science &Nutrition, Volume 14, Issue 8, August 2026.
Green and variegated Alternanthera bettzickiana morphotypes were compared after optimizing extraction (Box–Behnken design–RSM: 90% ethanol, 50°C, 2 h, 10 mg/mL). The green morphotype had higher phenolic content, FRAP, and ORAC activity, while the variegated morphotype had higher flavonoid and anthocyanin content.

Potent Therapeutic Insights From Eryngium campestre: Phytochemical Profiling and In Vitro Evaluation

Food Science &Nutrition, Volume 14, Issue 8, August 2026.
The phytochemical profiles and biological activity of ethyl acetate, ethanol, ethanol‐water, and water extracts of Eryngium campestre were assessed. E. campestre is a prospective source of multifunctional bioactive chemicals for food and nutraceutical uses, as demonstrated by the extracts' potential antioxidant, enzyme‐inhibitory, anticancer ...

Green and Rapid Determination of Phthalates in Mineral Water From Virgin and Recycled PET Bottles

Journal of Mass Spectrometry, Volume 61, Issue 8, August 2026.
ABSTRACT This study investigates the presence and quantification of phthalates released into mineral waters from virgin and recycled polyethylene terephthalate (PET) bottles. A green, solvent‐free analytical method based on solid‐phase microextraction (SPME) coupled with gas chromatography–mass spectrometry (GC/MS) was developed and validated to detect

Application of 2D‐Chromatography System for the Determination of Cosmetic Peptides in Skin Homogenates

Journal of Mass Spectrometry, Volume 61, Issue 8, August 2026.
ABSTRACT Peptides are increasingly employed as active ingredients in both therapeutic and cosmeceutical applications due to their high biological specificity, favorable safety profiles, and expanding market relevance. In topical formulations, peptide activity is typically confined to the skin, where widespread dermal proteases may significantly affect ...

Effect of SBS Copolymer Molecular Structure on the Long‐Term Aging and Resilience of Asphalt Binders: A Multiscale Morphological Study

Macromolecular Materials and Engineering, Volume 311, Issue 8, August 2026.
Vinyl content governs the long‐term ageing resistance of SBS‐modified bitumen. Multiscale AFM, FM, SEM, and FTIR analyses show that low‐vinyl SBS copolymers (L‐SBS, B‐SBS) undergo pronounced bee‐phase growth, stiffening, and network fragmentation after PAV ageing, whereas high‐vinyl variants (HV‐SBS, DB‐SB) retain their morphology and chemistry ...
