Application Note: Identification and Quantification of Plant Extracts Using Automated Nuclear Magnetic Resonance
13 August 2015

Valued for the perceived benefit derived from their natural compounds, botanical extracts are key ingredients in nutraceuticals and personal care products. This application note demonstrates the procedure and the ability to automate the NMR analysis of goldenseal extract for use in botanical identity, evaluating identity and quantity of components and for quality control. Most previous researchers have used LC-UV methods to quantify berberine, canadine and hydrastine in goldenseal and lack highly compound specific information. NMR provides an information rich, fully automated, rapid assessment tool that enhances assurances of product composition.
