Study: DNA barcoding can ID natural health products
Date:9/19/2012

DNA barcoding developed by University of Guelph researchers has proven up to 88 per cent effective in authenticating natural health products, according to a new U of G study.

The study appears in the latest issue of Food Research International.

It's a crucial finding because the health product industry is under-regulated worldwide and mislabelling poses economic, health, legal and environmental implications, says study author Mehrdad Hajibabaei.

"Currently there is no other broadly applicable tool that can identify the species used in both animal and plant natural health products as rapidly and cost-effectively," said Hajibabaei, a U of G integrative biology professor and director of technology development for the Guelph-based Biodiversity Institute of Ontario (BIO).

Up to about 80 per cent of people in developed countries use natural health products, including vitamins, minerals and herbal remedies. In Canada, these products have been regulated since 2004. But regulators face a backlog of licence applications, and thousands of products on the market lack a full product licence. In the U.S. and the U.K., regulatory problems involving natural health products have affected consistency and safety.

Authenticating natural product capsules or tablets -- containing dried fragments rather than whole specimens -- poses challenges.

DNA barcoding allows scientists to use short standardized regions of genetic material to identify species and compare them to reference genetic sequences, said Hajibabaei.

The technique works for all life stages and even for fragments of organisms, allowing scientists to ID even dried contents of a small pill.

"DNA barcoding provides a simple and efficient method for accurate identification and can play a key role in developing a more robust protocol for their regulation," Hajibabaei said.

For the study, researchers tested 95 plant and animal products bough
