Determination of total and free polyphenols in plant material using UV-VIS spectrophotometry. Accuracy and reliability with FITOSOIL LABORATORIOS.
Polyphenols are organic compounds of plant origin that play a key role in the quality and functionality of many natural raw materials and products. They are considered plant secondary metabolites, and their content may vary depending on plant species, growing conditions, maturity stage and processing methods.
For this reason, the analysis of total and free polyphenols in plant material is essential for sectors such as the agri-food, agricultural, biotechnology and natural products industries.
What Information Does Polyphenol Analysis Provide?
Determining the polyphenol content of plant material provides valuable analytical data to support both technical and commercial decision-making, including:
- Characterisation and differentiation of plant-based raw materials, allowing comparison between varieties, origins and batches.
- Assessment of product quality and batch consistency, supporting quality and process control.
- Analytical support for the development and validation of natural-origin products, such as plant extracts and biostimulants.
- Reliable analytical data for quality control, research and development (R&D) and continuous improvement.
In an increasingly demanding market, accurate and reproducible analytical results are essential to ensure product value and performance.
Polyphenol Determination Method at Fitosoil Laboratorios:
At Fitosoil, we carry out the determination of total and free polyphenols in plant material, expressed as catechin, using UV-VIS spectrophotometry.
The analysis is performed following standardised procedures, applied under strict quality criteria to ensure:
- Analytical accuracy
