Assessing the Dilution of Herbal Extracts Using Nuclear Magnetic Resonance

Ensure authenticity and quality of botanical products with advanced NMR-based analysis. This application note demonstrates how NMR spectroscopy accurately identifies species, detects dilution, and quantifies extract-to-carrier ratios—even in complex blends with excipients like maltodextrin, inulin, or XOS. Learn how non-targeted metabolomic profiling and multivariate statistical analysis deliver robust insights into product composition, while targeted screening enables biomarker quantification in a single workflow. Explore case studies on Ginkgo biloba, Panax ginseng, Silybum marianum, and Cordyceps militaris to see how NMR ensures compliance, transparency, and consumer trust. The following analytical concerns are addressed in this note:

  • Can NMR determine species authenticity of diluted products?
  • Can NMR identify product dilution and assess the fractions of extract and diluent in a product?
  • Can NMR identify the diluent type present?
  • Can NMR assess the drug extract ratios of products?
  • Can NMR methods simultaneously deliver targeted and non-targeted screening?
