What is the standard for Ginkgolic Acid?
It is widely found in the leaves, fruits and roots of Ginkgo biloba. According to the number of carbon atoms in the side chain and the differences in single and double bonds, it mainly includes ginkgo acid, hydrogenated ginkgo acid, hydrogenated ginkgo acid and ginkgo acid. Because of its biological toxicity, there are strict regulations during the production process.
WHO and multinational pharmacopoeias require that the total ginkgolic acid content in ginkgo extracts and preparations must be less than 5 ppm. The 2010 version of the Chinese Pharmacopoeia also requires that the content of ginkgolic acid in ginkgo leaf extracts be less than 10 ppm.
