Ground Kudzu (Pueraria montana var. lobata) Rhizome

This Reference Material (RM) is intended primarily for use in evaluating analytical methods for the determination of isoflavones and elements in kudzu rhizomes and similar matrices.

RM 8650 provides a common matrix to those in the botanical supplements community who may wish to conduct research studies.

This RM has also been characterized for its DNA sequence.

A unit of RM 8650 consists of five packets, each containing approximately 3 g of kudzu rhizome powder.

The development of RM 8650 was a collaboration among the National Institute of Standards and Technology (NIST), the National Institutes of Health Office of Dietary Supplements (NIH ODS), and the Food and Drug Administration Center for Drug Evaluation and Research (FDA CDER).

The addition of genetic information was accomplished through collaboration among NIST, NIH ODS, the U.S. Department of Agriculture Agricultural Research Service (USDA ARS), NSF International (formerly AuthenTechnologies®, Richmond, CA), and American Herbal

Pharmacopoeia (Scotts Valley, CA).
