Abstract

The invention relates to the field of medicament detection, and more specifically relates to a high performance liquid chromatography for simultaneously measuring the contents of gingko leaves (or extracts thereof) and multiple components in a preparation thereof. The method can be used for simultaneously measuring the contents of gingko leaves (or extracts thereof) as well as 14 flavonoid compounds and 2 phenolic acid compounds in a preparation thereof, and a new analysis method and basis are thus provided for quality control of commercial gingko leaf preparations.

Description

technical field [0001] The invention relates to the field of drug detection, more specifically, the invention relates to a high-performance liquid chromatography detection method for simultaneously determining the content of multiple components in ginkgo biloba extract and its preparation. Background technique [0002] Ginkgo is one of the oldest plants on earth. It is a plant of the Ginkgo family Ginkgo family. This tree species has strong vitality. It is not uncommon for a tree to be thousands of years old. It can be called the "old birthday star" in the plant world. It is recorded in "Compendium of Materia Medica" that Ginkgo biloba can invigorate the heart and nourish Qi, nourish the kidney and moisten the lungs, strengthen the brain and refresh the mind, and prolong life. Modern pharmacological studies have shown that Ginkgo biloba has the functions of scavenging oxygen free radicals, lowering blood fat, enhancing central nervous system function, regulating neurotransmi...
