Toolbox for the Extraction and Quantification of Ochratoxin A and Ochratoxin Alpha Applicable for Different Pig and Poultry Matrices
Autor: Barbara Streit, Tibor Czabany, Georg Weingart, Martina Marchetti-Deschmann, Shreenath Prasad
Publikováno v: Toxins, Vol 14, Iss 7, p 432 (2022)
Ochratoxin A (OTA) is one of the major mycotoxins causing severe effects on the health of humans and animals. Ochratoxin alpha (OTα) is a metabolite of OTA, which is produced through microbial or enzymatic hydrolysis, and one of the preferred routes

Establishment and Application of a Metabolomics Workflow for Identification and Profiling of Volatiles from Leaves of Vitis vinifera by HS-SPME-GC-MS
Autor: Georg Weingart, Astrid Forneck, Bernhard Kluger, Rainer Schuhmacher, Rudolf Krska
Publikováno v: Phytochemical Analysis. 23:345-358
Introduction Volatile organic compounds (VOCs) occurring in leaves of plants carry information about the physiological state of the plant. Monitoring of VOCs assists in detecting plant stress before visible signs are present. Objective To establish a

Determination of geosmin and 2,4,6-trichloroanisole in white and red Austrian wines by headspace SPME-GC/MS and comparison with sensory analysis
Autor: Georg Weingart, Reinhard Eder, Gerhard Sontag, Heidi Schwartz
Publikováno v: European Food Research and Technology. 231:771-779
This paper describes the development and application of a fast and simple headspace solid phase microextraction GC–MS method for simultaneous determination of geosmin and 2,4,6-trichloroanisole (2,4,6-TCA), two main contributors to off-flavors in w

metaMS: An open-source pipeline for GC–MS-based untargeted metabolomics
Autor: Ron Wehrens, Georg Weingart, Fulvio Mattivi
Publikováno v: Journal of Chromatography. B, Analytical technologies in the biomedical and life sciences, 966, 109-116
Journal of Chromatography. B, Analytical technologies in the biomedical and life sciences 966 (2014)
Untargeted metabolomics are rapidly becoming an important tool for studying complex biological samples. Gas chromatography–mass spectrometry (GC–MS) is the most widely used analytical technology for metabolomic analysis of compounds that are vola

Quantitative metabolic profiling of grape, apple and raspberry volatiles compounds (VOCs) using a GC/MS/MS method
Autor: Cesare Lotti, Urska Vrhovsek, Silvia Carlin, Fulvio Mattivi, Georg Weingart, Domenico Masuero
Nowadays the trend in analytical chemistry is clearly towards the creation of multiple methods with extended coverage, enabling the determination of many different classes of compounds in a single analysis in which virtually all classes of different

The volatile metabolome of grapevine roots: first insights into the metabolic response upon phylloxera attack
Autor: Georg Weingart, Rainer Schuhmacher, N.C. Lawo, Astrid Forneck
Publikováno v: Plant Physiology and Biochemistry
Many plant species respond to herbivore attack by an increased formation of volatile organic compounds. In this preliminary study we analysed the volatile metabolome of grapevine roots [Teleki 5C (Vitis berlandieri Planch. × Vitis riparia Michx.)] w
