Characterization of Grape Cane Stilbenoids and Their Photo‐Degradation Products by HPLC‐DAD Coupled With Trapped Ion Mobility Spectrometry and High‐Resolution Tandem Mass Spectrometry

Rapid Communications in Mass Spectrometry, Volume 40, Issue 15, 15 August 2026.
ABSTRACT Rationale Bioactive (E)‐stilbenoids in vine extracts are prone to light‐induced transformation into the respective (Z)‐isomers and further degradation products, often resulting in a loss of bioactivity. We sought to study stilbenoid degradation beyond that of the well‐researched resveratrol due to the high diversity of stilbenoids in nature ...

Optimized SPE‐HPLC‐FLD Method for the Simultaneous Determination of Olaparib, Propranolol, and Furosemide in Human Urine

Biomedical Chromatography, Volume 40, Issue 8, August 2026.
ABSTRACT Olaparib belongs to the PARP inhibitors and is widely used as an anticancer drug. Due to frequent side effects, it is usually co‐administered with an antihypertensive, such as propranolol and/or an antidiuretic, such as furosemide. In this study, a highly sensitive HPLC‐FLD method was developed for the simultaneous determination of the three ...

Effect of Fruit Maturation Stage on the Chemical Composition and Antioxidant and Cytotoxic Activities of Piper nigrum Essential Oil

Flavour and Fragrance Journal, Volume 41, Issue 4, Page 908-922, July 2026.
The essential oils of Piper nigrum show marked chemical and biological variation across fruit maturation stages. Ripe fruits yield oils with the strongest antioxidant and cytotoxic activities, demonstrating that maturation directly modulates volatile composition and enhances the bioactive potential of this aromatic species.
