Embodiment 1

[0022] (1) Raw material pretreatment: Take 100kg of fresh ginkgo seed kernels and crush them with strong ultrasonic;

[0023] (2) Add water and mix: (1) Add medium crushed fresh ginkgo seed kernels to 5 times the mass of water, mix well and filter to obtain liquid A;

[0024] (3) Solvent leaching: (2) add ethanol which is half the weight of water to the liquid in (2) for leaching, and filter with suction to obtain liquid B;

[0025] (4) Heating up: Liquid B is gradually heated up to 100°C of ginkgool, during which ethanol and water are distilled off to obtain an oily substance, which is ginkgool.

[0026] The determination of ginkgophenol adopts Agilent Technologies 1200 Series; the column temperature is 35°C, and the chromatographic column is TC-C 18 .

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.

Description

technical field [0001] The invention belongs to the technical field of extraction of natural plant active ingredients, and in particular relates to an ultrasonic extraction and purification extraction method of ginkgo biloba. Background technique [0002] Ginkgo biloba, 1,3-dihydroxy-5-(cis-8′-pentadecenyl)benzene, is a colorless or light yellow oily or powdery substance, a polyphenolic compound that exists in ginkgo leaves, fruit And in the outer testa, it has a variety of important physiological activities. [0003] Epidemiological surveys and scientific experiments have shown that ginkgo biloba can effectively prevent cardiovascular diseases, rectal cancer, breast cancer and other cancers, and has preventive effects on obesity, diabetes and other chronic diseases. [0004] At the same time, Ginkgo biloba has the following medicinal effects: (1) It has anticancer activity against Ehrlich ascites carcinoma, SN36 leukemia and sarcoma 180; (2) Antibacterial effect: against S...
