Researchers from University of La Rioja commissioned by IGUSOL ADVANCE S.A., presented their findings at the XXIV National Meeting on Spectroscopy – VIII Iberian Conference on Spectroscopy held from July 9-11 in Logroño (La Rioja), Spain.
The interest in using natural products with therapeutic properties as feed additives has increased in recent years. Chlorogenic acids (CQAs) and caffeoylquinic acids are naturally present in several herbs, and possess multiple preservative and pharmacological properties, such as antioxidant, antiviral, antibacterial, anti-inflammatory, detoxifying, choloretic and colagogue activities.
Production assumes that the “right” raw material was selected for the product. But quality assurance of raw materials is a central part of the process. All raw materials need to be checked to conform to the specifications. This process includes at least selection-characterisation of the raw material and analytical quality control (AQC) requirements to support the validity of data reported.
In this communication, CQAs determination in three sources (herbal extract, feed additive and complete feed) using a novel method based on Focused Ultrasound Solid-Liquid Extraction (FUSLE) followed by Ultra-high Performance Liquid Chromatography (UPLC) coupled to quadrupole-time of flight mass spectrometry was presented.
Results from the scientific group revealed 5-caffeeoylquinic acid was the predominant CQA with good recovery rates in all samples. They concluded from their research that the proposed method may be used for screening of raw material and for analytical quality control in the feed industry.
