Non‐Destructive Analysis of Phenolic and Flavonoid Contents in Medicinal Plant Powders Using Hyperspectral Imaging and Variable Selection

Analytical Science Advances, Volume 7, Issue 2, December 2026.
ABSTRACT Phenolic and flavonoid contents in medicinal plants are essential to their growth and development and provide numerous health benefits, yet their quantification using traditional wet chemistry is labor‐intensive and time‐consuming. This study utilized the combination of two benchtop hyperspectral imaging (HSI) systems, namely short‐wave ...

Rapid Quantitative Determination of Enantiomeric Excess by Vibrational Circular Dichroism Using Noise Based Spectral Selection

Chirality, Volume 38, Issue 9, September 2026.
Rapid VCD‐based determination of enantiomeric excess in limonene is achieved using signal‐to‐noise guided spectral selection and multivariate modeling. While 30‐min spectra provide high accuracy, 5‐min acquisitions retain ~97% performance, enabling faster throughput and offering a practical approach for rapid, reliable chiral analysis in applications ...

Olive Oil Quality Analysis and the Detection of Adulterations by GC‐MS With Cold EI

Journal of Mass Spectrometry, Volume 61, Issue 9, September 2026.
ABSTRACT Olive oil is widely consumed for its nutritional and health benefits, yet its high market value makes it vulnerable to adulteration and mislabeling. Current analytical approaches for assessing olive oil quality and authenticity rely largely on indirect analyses, such as fatty acid methyl ester (FAME) profiles, peroxide values, or UV absorbance,

Smart detection of juice adulteration: An approach based on ion mobility spectrometry and machine learning

Journal of the Science of Food and Agriculture, Volume 106, Issue 12, Page 7406-7415, September 2026.
Abstract BACKGROUND Fruit juice quality is regulated by European Union legislation; however, adulteration by adding cheaper alternatives, such as white grape juice, remains a prevalent issue. This practice constitutes economic fraud and poses health risks to consumers, including potential allergic reactions to the adulterant.

A comprehensive checklist of Mediterranean wild edible plants: Diversity, traditional uses, and knowledge gaps

PLANTS, PEOPLE, PLANET, Volume 8, Issue 5, Page 1616-1633, September 2026.
The use of wild edible plants and the traditional knowledge associated with them are rapidly disappearing across the Mediterranean, with serious consequences for biodiversity, cultural heritage, and regional food security. This study compiles and organizes fragmented information to create the first comprehensive catalogue of these plants across the ...

Crossroads of the Life of Vittorio Alfieri

Journal for Eighteenth-Century Studies, Volume 49, Issue 3, Page 375-392, September 2026.
Abstract This article examines Vittorio Alfieri's Life as a deliberately constructed narrative of cultural, linguistic, and political self‐fashioning within eighteenth‐century European intellectual networks. Rather than treating the autobiography as a transparent record of experience, the article argues that Alfieri retrospectively reorganizes his ...
