Tannin is a class of natural polyphenolic compounds with an astringent flavor and the ability to produce browning. Its structural monomers are mainly catechol, o-benzenetriol, and m-benzenetriol, which are widely found in plants' leaves, fruits, roots, and skins. Tannins have various biological activities, such as antibacterial, antioxidant, etc., which impact the growth, development, and health of plants and animals. Lifeasible provides a comprehensive range of targeted quantitative services, including but not limited to tannin quantitative analysis. Our comprehensive range of tannin quantitative analytical services is designed to assist researchers in progressing plant research and food science studies.

Sample handling and pre-treatment

• Sample types. The types of samples we receive include plant tissues (fresh or frozen), food ingredients (e.g., grains, wines), herbal medicines, industrial extracts, and more.
• Sample extraction. Depending on the sample type (e.g., plant tissue, fruit, etc.), we use appropriate extraction methods to ensure that tannins are adequately extracted.
• Purification & concentration. This part of the process includes the removal of impurities to improve the accuracy and sensitivity of the analysis.

Analytical assays

The scope of our assays is shown below.

• Total tannin determination. Rapid assessment of total polyphenol content based on spectrophotometry.
• Tannin fraction identification and quantification. Accurate analysis of hydrolyzed tannins (e.g., gallic acid, ellagic acid) and condensed tannins (e.g., proanthocyanidins, flavan-3-ols) by high-resolution mass spectrometry (LC-MS/MS, GC-MS/MS).
• Functional activity evaluation. Combined with antioxidant and bacteriostatic experiments, the biological activities of tannins were analyzed.

Data processing and analysis

• Data acquisition and organization. Preliminary processing of the data collected by the instrument to ensure the completeness and accuracy of the data.
• Quantitative analysis. Quantify the tannins using the standard curve and internal standard methods to provide accurate content data.
• Interpretation and reporting. According to the analysis results, provide customers with a detailed analysis report, including sample information, analytical methods, result data, conclusions, etc., to help customers understand the significance and application value of the data.
