Problems solved by technology

Ginkgo biloba products are currently available in various formulations. Ginkgo orally disintegrating tablet is a fast-dissolving ginkgo preparation with the characteristics of fast absorption and high absorption rate. Chinese patent application 200310123852.1 describes the prescription and preparation of a ginkgo orally disintegrating tablet Method, due to the particularity of orally disintegrating preparations, its quality control method has not been well resolved for a long time. For ginkgo preparations, there is no quality control method for ginkgo orally disintegrating tablets in the prior art. The quality control methods of other dosage forms are directly used for orally disintegrating tablets, and there is a problem of inaccurate detection. Therefore, it is a problem that medical workers need to solve to study an effective quality control method with high accuracy and reasonable
