From bitter toxins to bioactive assets: redefining quinolizidine alkaloids in Lupinus spp.
Hajer Ben Ammar, Barbara Pipan, Lovro Sinkovič
Pregledni znanstveni članek
Oznake: Lupinus;quinolizidine alkalois;food safety;analytical methods;detoxification;functional bioactivity;
Lupins (Lupinus spp.) are climate-resistant grain legumes gaining attention as sustainable protein sources. However, their use in the human diet is limited by quinolizidine alkaloids (QAs), a class of nitrogenous secondary metabolites. QAs represent a nutritional paradox: They are central to plant d ...

Optimised extraction and HPLC–DAD determination of steroidal glycoalkaloids in potato tubers
Hajer Ben Ammar, Peter Dolničar, Barbara Pipan, Lovro Sinkovič
Izvirni znanstveni članek
Oznake: α-chaconine;α-solanine;analytical method;HPLC-DAD;potato tubers;environmental sustainability;
Steroidal glycoalkaloids ( α-solanine and α-chaconine) are major potato toxins whose accurate quantification is often challenged by matrix effects and chromatographic selectivity. This study reports the optimisation and validation of a robust reversed-phase HPLC-DAD method for the determination of g ...

ǂThe ǂorganic-conventional trade-off: Grain yield, nutritional composition and quality traits across diverse cereals
Lovro Sinkovič, Hajer Ben Ammar, Marianna Rakszegi, Péter Mikó, Barbara Pipan
Izvirni znanstveni članek
Oznake: cereals;grain yield;multi-year field experiment;micronutrients;β-glucan;proteins;nutritional quality;CONV;
This study evaluated the effects of conventional (CONV) and organic (ORG) management on grain yield, nutritional composition and quality traits of winter barley, winter spelt, spring oat and winter wheat over a three- year field experiment. The aim was to identify species-specific productivity-quali ...

Integrating metabolic and gene expression profiling of glucosinolate biosynthesis under drought stress in Brassica oleracea
Hajer Ben Ammar, Souhir Kabtni, Donata Arena, Marwen Amari, Nicolas Al Achkar, Ferdinando Branca, Sonia Marghali
Izvirni znanstveni članek
Oznake: glucosinolate;gene expression;qRT-PCR;abiotic stress response;drought stress;
Drought stress induces pronounced metabolic and transcriptional reprogramming of glucosinolate (GLS) biosynthesis in Brassica oleracea. An integrative approach combining HPLC-based quantification of individual GLSs, quantitative real-time PCR of core biosynthetic and regulatory genes, correlation-ba ...

Comparative life cycle assessment of olive (Olea europaea L.) production under different agricultural systems: Environmental trade-offs and sustainability insights
Makrem Cherni, Hajer Ben Ammar, Mohamed Guesmi, Rabii Lanwer, Yassine Hidri, Khaled Ouertani, Hakim Boulal, Boubaker Dhehibi, Ajmen Frija, Ajmi Larbi
Izvirni znanstveni članek
Oznake: Olive cultivation;Life cycle assessment (LCA);Ecosystem impacts;Agri-environmental indicators;Mediterranean cropping systems;
Introduction Olive cultivation is a major agroecosystem in the Mediterranean basin, yet the environmental performance of its production systems remains poorly quantified, particularly in North Africa where life cycle inventory (LCI) data are limited. Methods This study applied a comparative Life Cyc ...
