Ultrasonic extraction, purification and extraction method of ginkgol

Abstract

The invention relates to an ultrasonic extraction, purification and extraction method of ginkgol, and belongs to the technical field of natural plant active ingredient extraction. The method comprisesthe following steps: carrying out strong ultrasonic fragmentation on fresh gingko kernels, mixing with water, filtering, carrying out solvent extraction, and finally heating to a ginkgol gasificationtemperature to obtain an oily substance, namely the ginkgol. The method for independently extracting the ginkgol is provided for the first time, the method is simple in process, low in cost and goodin effect, the required component ginkgol can be effectively enriched and separated, and the quality and content of the ginkgol extract are improved.
