Document Type and Number:
WIPO Patent Application WO/2021/232932
Kind Code:
A1
Abstract:
A method for preparing high-purity granatin A: by means of a combination of low-temperature liquid phase chromatography and an isomerisation conversion purification method, using pomegranate peel extract as a source material, granatin A of over 98% purity can be acquired, and can be used as a standard product for quality control of pomegranate peel, pomegranate flower, or other medicinal material with granatin A as the active ingredient.
