Cedrela fissilis Vell. Inner Bark: LC–MS/MS‐Based Chemical Profiling and Toxicological Effects

Chemistry &Biodiversity, Volume 23, Issue 5, May 2026.
ABSTRACT Investigating the mechanistic toxicity of plant extracts is essential for safety assessment. The predictive toxicological effects of Cedrela fissilis were evaluated, and LC–MS/MS‐based chemical profiling was performed. The hydroethanolic extract (HeECf) and ethyl acetate (EA) fraction were assessed in multimodel systems with different levels ...

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

Comparative Phytochemical and Fatty Acid Profiling of Flax (Linum usitatissimum L.) Cultivars Across Diverse Geographic Origins

European Journal of Lipid Science and Technology, Volume 128, Issue 5, May 2026.
Flax varieties differ in growth, oil quality, and beneficial compounds, but these differences are not always clear‐cut. In this study, 10 flax types were grown under the same conditions and compared for plant traits, natural compounds, and oil content. Some showed high omega‐3 and lignan levels, making them valuable for healthier foods and future crop ...

Correlational and Molecular Mechanism Analyses of Bioactive Compounds From Ziziphus jujuba: Focusing on Anti‐Hyaluronidase and Antioxidant Networks

Food Science &Nutrition, Volume 14, Issue 5, May 2026.
Extract of Z. jujuba leaves and branches is prepared by using ethanol. The samples are examined for antioxidant and various enzyme inhibition activities. Then, bioactive components are isolated by column chromatography and identified by EI‐MS, NMR, and UV‐HPLC. Medicagenic acid may be the best candidate for anti‐hyaluronidase.

Temperature‐Assisted Crystallization of Mustard Oil for Erucic Acid Reduction and Its Impact on Phenolic Compounds, Sterols and Oxidative Quality of Oil During Ambient Storage

Food Science &Nutrition, Volume 14, Issue 5, May 2026.
Erucic acid (EA) content of mustard oil (MO) was decreased to < 2% level using temperature‐assisted crystallization with no effect on free fatty acids (FFAs), peroxide value (PV), and color of MO and its olein and stearin variant. Olein was rich in phenolic compounds and had higher antioxidant capacity than MO and stearin.

Biocompatibility and Therapeutic Potential of Cinnamoyl‐Diphenylalanine Dipeptide: A Double‐Edged Sword

Journal of Biomedical Materials Research Part A, Volume 114, Issue 5, May 2026.
Cin‐FF's biocompatibility is concentration and formulation (gel or solution) dependent, showing varied effects on bacterial strains and cell lines. ABSTRACT This study evaluates cinnamoyl‐diphenylalanine dipeptide (Cin‐FF), a newly introduced gelator, for its antimicrobial efficacy, biocompatibility, and potential anticancer properties in solution and ...
