DNA Barcoding of Dietary Supplements
Damon Little and collaborators
In the United States, approximately 17% of adults and 9% of children consume herbal supplements. Regulations to ensure product quality are very limited, resulting in a wide range of quality and sporadic reports of adulteration. Generally, marketers purchase bulk lots of morphologically unidentifiable plant materials (e.g., in powder form) and package it for retail sale. Because identity of the plants cannot be easily verified, adulterated or illegal products are sometimes sold to the public—often without the marketer’s knowledge. We have developed DNA techniques that can reliably determine which plants are included in a number of herbal products.
