Nutraceutical Profiling
Differentiate your nutraceutical product from the market with high quality analytics. Certifying your product using validated methods and high-quality reference standards can make all the difference, especially when the marketplace is flooded with low quality products,. Elevate your business using nutraceutical profiling and give yourself an edge in the market.
Our team of experts are here to help you with your product profiling and certification needs. For example, we offer services ranging from routine HPLC analysis using USP monographs to custom developed novel analytical methods. Additionally, if the reference standards aren’t available, or even established, we can produce high purity and well characterized standards that will satisfy all regulatory groups.

Examples of Nutraceutical Profiling Methods
Gravimetric Standardization by HPLC
One of the best methods to accurately profile the active ingredients in your nutraceutical product is through gravimetric standardization using HPLC analysis. In short, the concentration of your active ingredients is determined by comparing their concentration dependent detector response against a calibration curve prepared using reference standards. Most commonly UV detection is used, but mass spectrometry offers benefits when dealing with compounds with weak chromophores, or at low concentrations.
Colorimetric Standardization
Folin–Ciocalteu Assay
The Folin-Ciocalteu (Folin-C) assay is an effective means for determining total phenolic and poly-phenolic content. In effect, it presents phenolic content as a “Gallic Acid equivalent” (GAE) as assay uses gallic acid as the reference.
DMAC ASSAY
4-(Dimethylamino) Cinnamaldehyde (DMAC) Assay is a validated method for determination of total soluble PACs (proanthocyanidins). For example, it’s well suited to profiling products like cranberries and related nutraceuticals. It also offers the benefit of being able to provide information on the relative quantities of A-type vs B-type bonds present in the PACs.
Service Supplement
RAPID STRUCTURAL IDENTIFICATION BY MALDI-TOF/TOF MS
ABSTRACT: Although procyanidins constitute a unique class of polymeric plant secondary metabolites with a variety of biological properties including potent antioxidant activity, structure determination has been challenging, and structures of many complex procyanidins remain uncertain. To expedite the characterization of procyanidins, negative ion matrix-assisted laser desorption ionization high-energy collision-induced dissociation tandem time-of-flight (MALDI-ToF/ToF) mass spectra of 20 isolated procyanidins containing catechin and epicatechin subunits with degrees of polymerization up to five were obtained and evaluated. Structurally significant fragmentation pathways of singly charged, deprotonated molecules were identified representing quinone methide, heterocyclic ring fission, and retro-Diels-Alder fragmentation. The interpretation of the tandem mass spectra for sequencing A-type, B-type, mixed-type, linear, and branched procyanidins is explained using specific examples of each.
