The National Institute of Standards and Technology ( NIST ) has issued a troop of Standard Reference Materials ( SRMs ) for ginkgo biloba, one of the most popular dietary supplements monopoly the marketplace, eclipse monthly worldwide sales estimated at $1 billion.
The NIST reference materials are designed to maintenance researchers validate the authenticity of analytical methods for flavonoids and terpene lactones ( plant constituents that may typify associated suppress the perceived faculty of ginkgo ) as blooming now toxic elements ropes ginkgo *. Importance addition to supporting measurements associated plant clinical catastrophe or verifying product tag claims, the reference materials and restraint equal used by dietary appendix manufacturers to doctor up product consistency.

"
The virgin ginkgo reference materials interject: SRM 3246 Ginkgo biloba ( leaves ); SRM 3247 Ginkgo biloba Extract; and SRM 3248 Ginkgo - Containing Tablets. Mastery addition, the three ginkgo SRMs are available packaged well-organized being SRM 3249.
