Sabinsa has raised the quality bar for the popular adaptogen ashwagandha with Shagandha Ashwagandha Root Extract 2.5% USP from Withania somnifera, assured to comply with the U.S. Pharmacopoeia-National Formulary (USP-NF) monograph. The company chose botanical specialist Alkemist Labs to test the ingredient to confirm that it meets the USP monograph.
“We did two tests for Sabinsa’s Shagandha Ashwagandha Root Extract 2.5% USP material; an identity test by HPTLC and a quantitative test for Withanolides by HPLC,” confirmed Alkemist Labs CEO Elan Sudberg. “The identity testing by HPTLC was performed to show that their material is consistent with Withania somnifera root. The quantitative testing for Withanolides, compounds within ashwagandha, by HPLC was performed to show the amount of withanolides in their Shagandha extract. This testing was to show that they meet their 2.5% withanolide specification they claim on this product. In both testing cases, United States Pharmacopeia (USP) methods were used. Essentially, the test showed Sabinsa’s Shagandha extract is authentic ashwagandha.”
“With ashwagandha sales growing in the double digits in recent years, extra caution in sourcing becomes crucial to guard against the adulteration that often follows rapid growth in demand for an herb,” said Sabinsa founder Dr. Muhammed Majeed. “Ensuring identity of the material and that it will meet our specification claims fits with our commitment to combating adulteration in the supply chain while assuring customers we provide quality ingredients.”
Authenticity of ashwagandha was the subject of a recently published bulletin by the ABC-AHP-NCNPR Botanical Adulterants Prevention Program (BAPP): Adulteration of Ashwagandha (Withania somnifera) Roots and Extracts, available at HerbalGram.
