PPMLS™ (Polyphenol Metabolite Library of Standards) is a collection of high-quality small biochemicals that have a polyphenolic structure (i.e., several hydroxyl groups on aromatic rings). Polyphenols are found in many plant foods including fruits, vegetables, cereals, dry legumes, chocolate, oils, spices and some beverages, including red wine.  Polyphenols are a class of compounds which include flavonoids, phenolic acids, lignans, and stilbenes.  In plants, these secondary metabolites are generally involved in stress defense.  Studies of polyphenol compounds show evidence of anti-oxidative properties and their consumption may limit the risk of degenerative diseases associated with oxidative stress and inflammation.

We provide these are high purity (>95%) compounds in an economical, ready-to-use format.  These standards are most commonly used to provide retention times and spectra for these key metabolic compounds, help optimize mass spectrometry analytical protocols, and qualify and quantify mass spectrometry sensitivity and limit of detection.

PPMLS comes with MLSDiscovery™, a software tool to support the extraction, manipulation, and storage of the data generated when using Libraries of authentic metabolite standards produced by IROA Technologies.
