Creative Proteomics provides one-stop large molecule mass spectrometry (MS) services covering a wide variety of proteins and peptides. Our tannins analysis services use LC-MS/MS and GC-MS/MS technologies to deliver high resolution and reliable identification and quantification of tannins.

Overview

Tannins is an acidic substance, extracted from the grape seeds of the gall plant. As a natural preservative, it has antioxidant effect, can eliminate active oxygen in the human body, prevent cardiovascular disease, and beautify the skin. In industry, tannins is widely used in leather tanning and blue ink production. In medicine, tannins can increase the contractility of smooth muscle fibers in the intestinal muscular system, adjust the function of the colon, and have a certain effect on colitis. Mass spectrometry is a sensitive analysis technique. Even at low abundance, it can detect, identify and quantify various plant tannins by measuring its mass and characterizing its chemical structure. Mass spectrometry instruments can be combined with gas chromatography (GC) or liquid chromatography (LC) to effectively separate organic molecules from complex samples. Comprehensive tannins analysis helps to clarify how plants respond to different conditions such as mutations, stress and tannin treatments.

Applications of Tannins Analysis

  • Reveal mechanisms of plant development
  • Uncover plant's responses to biotic and abiotic stresses
  • Safety assessment of crops
  • Crop improvement
