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 ...

Natural Carbon Isotope Composition Distinguishes Compound Groups of Biogenic Volatile Organic Compounds (BVOC) in Two Mediterranean Woody Species

Frontiers in Forests and Global Change, 2019
Our knowledge on the biosynthesis of several biogenic volatile organic compounds (BVOCs) is still limited. In this regard, natural abundant stable carbon isotope ratios (δ13C) of BVOCs may provide a powerful tool to evaluate different metabolic pathways.

Expanding the substrate scope of a bacterial monoterpene synthase for the production of sesquiterpenoid and diterpenoid products

The FEBS Journal, Volume 293, Issue 5, Page 1341-1357, March 2026.
We have converted the only known true bacterial monoterpene synthase, cineole synthase from Streptomyces clavuligerus (bCinS, C10 substrate), to a highly competent sesquiterpene synthase (C15) with a minimum number of rational mutations. By comparison with diterpene synthases (C20), we were then able to bestow diterpene synthase activity on bCinS. This

Metabolomic and Single‐Cell Transcriptomic Analyses Shed Light on Secondary Metabolite Profiling and Potential Developmental Dynamics of Glandular Trichomes in Artemisia argyi

Plant Biotechnology Journal, Volume 24, Issue 3, Page 1064-1081, March 2026.
ABSTRACT Plant glandular trichomes (GTs) are characterised by their ability to synthesise and store abundant secondary metabolites of significant biological importance. The medicinal plant Artemisia argyi exhibits a dense covering of GTs, yet the precise metabolic compositions and the developmental molecular dynamics of A.

Aerobic Oxidative Dethioacetalization Catalyzed by an Iron Phthalocyanine Complex

Advanced Synthesis &Catalysis, Volume 368, Issue 2, January 2026.
A protocol for iron octacarboxyphthalocyanine‐catalyzed aerobic oxidative dethioacetalization in an aqueous solvent is developed. This method can efficiently convert a broad range of dithioacetals into the corresponding carbonyl compounds. Inspired by enzyme‐mediated redox processes, the environmentally friendly catalytic system exhibits remarkable ...

Shelf‐Life Extension of Chicken Fillets Using Flaxseed Mucilage Coatings Incorporated With Bixin‐Allicin or Bixin‐Orange Peel Essential Oil Nanoemulsions

Food Science &Nutrition, Volume 14, Issue 1, January 2026.
Flaxseed mucilage incorporated with bixin‐allicin or bixin‐orange peel oil nanoemulsions significantly extended the shelf‐life and quality of fresh chicken fillets. ABSTRACT This study evaluated the properties of orange peel essential oil (OPE) and allicin emulsions and their efficacy in flaxseed mucilage‐bixin (FM‐B) coating for preserving chicken ...

Iridoid and Acyclic Monoterpene Glycosides, Kankanosides L, M, N, O, and P from Cistanche tubulosa

Chemical and Pharmaceutical Bulletin, 2010
Three iridoid glycosides, kankanosides L, M, and N, and two acyclic monoterpene glycosides, kankanosides O and P, were isolated from fresh stems of Cistanche tubulosa (Orobanchaceae) together with eight iridoid glycosides, five acyclic monoterpene glycosides, three phenylpropanoid glycosides, and four lignan glycosides. Their structures were elucidated

Discovery and characterisation of terpenoid biosynthesis enzymes from Daphniphyllum macropodum

BMC Plant Biology
Terpene synthase (TPS) enzymes are known to be pivotal in the biosynthesis of terpenoids in plants and microbes. These enzymes catalyse the transformation of ubiquitous acyclic prenyl diphosphate substrates into diverse hydrocarbon skeletons.
