Eurofins BioDiagnostics | Botanical Identification

Eurofins BioDiagnostics laboratories have over 20 years of experience in botanical testing. When it comes to identifying quality and purity in botanicals, one test does not fit all which is why our labs utilize a four-pronged Orthogonal Approach to botanical identification. With a diverse variety of botanical samples to identify, it may take different tests to get reliable, consistent results. Utilizing all four elements of the Orthogonal Approach prevents human error, process failures, and inaccuracies.

Botanical Identification | DNA Barcoding
DNA Barcoding

Why DNA barcodes?

  • Plant microscopic tests are prone to human error and there are challenges with bulk samples
  • Chemical tests don’t have enough resolution to differentiate closely related species or find the fillers
  • DNA barcoding is more accurate and solves authenticity problems when it is difficult by other means

NGS (Next Generation Sequencing) & Sanger Sequencing Offerings

  • NGS works on mixed bulk samples and produce ratio of the components
  • NGS is appropriate for identifying contaminants or fillers
  • Sanger Sequencing is limited to the authenticity of a pure sample
  • We offer both NGS and Sanger Sequencing
Botanical Identification | Chemistry & Chromatography
Chemistry & Chromatography

Why chemistry and chromatography?

  • Recognized by US Pharmacopeia as one of the most common techniques for the identification analysis of botanical dietary supplements
  • Chromatographic methods (e.g. HPLC/GC) are generally more acceptable by the FDA’s cGMP criteria because they are easier to be proved as scientifically valid in most cases
  • DNA fingerprint will remain the same irrespective of the plant part used, while the phytochemical profile will vary with the plant part used. DNA-based methods may also not be suitable for botanical extract or processed ingredient.

Thin Layer Chromatography (TLC)

  • High-Performance Liquid Chromatography (HPLC)
  • High-Performance Thin Layer Chromatography (HP- TLC)
Botanical Identification | Microscopy

What is microscopy?

  • One of the oldest techniques to identify botanicals and determine quality.
  • Uses a microscope to examine and compare structure to a reference structure and is often the most accurate method for identifying raw botanical samples
  • Microscopy techniques can also be used to detect contamination
