Role of the Antioxidant Lycopene in Bone Health: Emphasis on the RANKL/RANK/OPG Signaling Pathway

Food Science &Nutrition, Volume 14, Issue 8, August 2026.
Bone health may be maintained through several interconnected mechanisms attributed to lycopene including its potent antioxidant, anti‐inflammatory, osteogenic, and anti‐resorptive actions. Lycopene may protect osteoblasts by reducing reactive oxygen species and stress‐mediated apoptosis.

Soft-MS and Computational Mapping of Oleuropein [PDF]

International Journal of Molecular Sciences, 2017
Olive oil and table olives are rich sources of biophenols, which provides a unique taste, aroma and potential health benefits. Specifically, green olive drupes are enriched with oleuropein, a bioactive biophenol secoiridoid. Olive oil contains hydrolytic derivatives such as hydroxytyrosol, oleacein and elenolate from oleuropein as well as tyrosol and ...

Tunable Natural Deep Eutectic Solvents‐Driven Fractionation of Olive Pomace in an Integrated Biorefinery: Linking Lignin Structural Tailoring to Carbohydrate Valorization and Biopolymer Production

ChemSusChem, Volume 19, Issue 13, 14 July 2026.
Microwave‐conditioned olive pomace was fractionated with deep eutectic solvents (DESs) spanning acidic, neutral, alkaline, and chemo‐enzymatic regimes. The alkaline DES provided the best balance between delignification and carbohydrate preservation, yielding a fermentable glucose/xylose stream suitable for Haloferax mediterranei fermentation and poly(3‐
