Bioactive Phytochemical Compounds in Medicago sativa L. (Alfalfa): A Systematic Review of Biological Properties and Therapeutic Relevance in Nutraceutical and Functional Food Implications

Food Frontiers, Volume 7, Issue 2, March 2026.
ABSTRACT Medicago sativa L. (alfalfa) harbors a remarkably diverse reservoir of bioactive secondary metabolites. Flavonoids, isoflavones, and triterpenoid saponins dominate its bioactivity landscape, driving potent antioxidant, anti‐inflammatory, antimicrobial, estrogenic, hypolipidemic, and cytotoxic actions through redox modulation, membrane ...

Gas/particle partitioning of carbonyls in the photooxidation of isoprene and 1,3,5-trimethylbenzene [PDF]

Atmospheric Chemistry and Physics, 2008
A new denuder-filter sampling technique has been used to investigate the gas/particle partitioning behaviour of the carbonyl products from the photooxidation of isoprene and 1,3,5-trimethylbenzene. A series of experiments was performed in two atmospheric

Obesity and Natural Products: Mechanisms, Therapeutic Potential, and Future Directions

Food Science &Nutrition, Volume 14, Issue 3, March 2026.
Natural products such as EGCG, berberine, curcumin, and capsaicin modulate key metabolic pathways including AMPK activation, adipogenesis inhibition, and inflammatory signaling. While clinical trials demonstrate modest benefits on body weight and metabolic parameters, translational challenges related to bioavailability, dose feasibility, and regulatory

Practical Applications of Secondary/Extractive Electrospray Ionization (SESI): A Versatile Tool for Real‐Time Chemical Analysis

Mass Spectrometry Reviews, Volume 45, Issue 2, Page 392-428, March/April 2026.
ABSTRACT In the 1980s, researchers discovered the remarkable ability of electrospray plumes to effectively ionize gas‐phase molecules via secondary ionization. Around 20 years later—coinciding with the ambient mass spectrometry revolution—secondary electrospray ionization (SESI) and extractive electrospray ionization (EESI) coupled to mass spectrometry

The Contribution of Cholesterol and Squalene Synthase in Cancer: Molecular Mechanisms, Lipid Rafts and Therapeutic Approaches

Medicinal Research Reviews, Volume 46, Issue 2, Page 352-381, March 2026.
ABSTRACT A plethora of cellular signaling pathways are dysregulated in cancer cells, promoting carcinogenesis and migration. Cholesterol has recently been linked to cancer by several subcellular mechanisms, especially by its involvement in the formation of lipid rafts, which promote oncogenic signaling and cancer cell invasion. Squalene synthase (SQS),

Progress in Surface‐Enhanced Raman Scattering‐Based Volatile Organic Compounds Detection: Materials, Application, and Prospects

Rare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT The detection of volatile organic compounds (VOCs) holds significant implications in environmental monitoring and disease diagnosis. Traditional gas detection technologies are constrained by complex operation and high cost, thereby failing to satisfy real‐time detection demands.

Electrocatalytic Reduction and Oxidation Conversion of Plant Biomass

Small Structures, Volume 7, Issue 3, March 2026.
This review therefore establishes a unified “compound–catalyst–conversion” paradigm, systematically categorizing and analyzing electrocatalytic oxidation and reduction pathways for the three major classes of plant‐derived components—aromatics, aliphatics, and terpenoids—to provide a clear navigational map for the field.
