Problems solved by technology

The organic solvent extraction method needs a large amount of extraction solvent, the production cost is high, the recovery rate is low, and it is easy to cause the change of the structure of the active substance and the decline of the activity.
Water infiltration deer extraction method has a long extraction period and low extraction rate, so the utilization rate of raw materials and production efficiency are low
[0004] In the invention patent CN200910307800.7, the membrane system composed of microfiltration (MF), ultrafiltration (UF), nanofiltration (NF) and reverse osmosis (RO) is used to separate and purify saffron, but the water leaching method used is prolonged production cycle
In the invention patent CN201010190584.5, macroporous adsorption resin chromatography is used for secondary separation and purification of crocin, which consumes excessive extraction and elution solvents and increases costs
At present, there is no integrated process technology that integrates online membrane separation and macroporous adsorption resin column chromatography purification to prepare high-purity saffron

Abstract

The present invention particularly relates to a nature crocin extraction separation method and preparation for a crocin blood fat reduction drug. The extraction separation method comprises: carrying out cleaning and impurity removing on dried cape jasmi fruits, extracting with deionized water, filtering to removing residue, carrying out online membrane separation and concentration fusion and macroporous absorption resin chromatography purification, and finally carrying out low-temperature spray drying to prepare the crocin. According to the present invention, the key of the invention is to create the extraction agent, and the water containing a certain auxiliary solvent is adopted to extract the crocin, wherein the extraction rate can be more than 95%; the online membrane separation and concentration fusion and the macroporous absorption resin chromatography purification are integrated; the high purity crocin production method has a characteristic of low cost and is suitable for industrial expansion production; and the compounded pharmaceutical preparation has effects of significant blood fat reduction, no side effect, effective cardiovascular and cerebrovascular related disease prevention, and blood circulation promotion, and is the preferred health care drug for crowds with high blood pressure, high blood fat and high blood sugar.

Description

technical field [0001] The invention belongs to the technical field of natural product extraction and separation, and also relates to the technical field of traditional Chinese medicine preparations. The invention relates to a preparation of high-purity saffron by using Gardenia jasminoides as raw materials, and a formula of a composite preparation of saffron, ginkgo leaf extract flavonoids and grape seed extract proanthocyanidin with the function of lowering blood fat. Background technique [0002] Gardenia is a plant genus of Rubiaceae, which is widely distributed in my country and is the first batch of medicinal and edible resources promulgated by the Ministry of Health. Gardenia has the effects of protecting the liver, promoting gallbladder, lowering fat, stopping bleeding, clearing away heat, and stopping diarrhea. Gardenia contains a variety of functional components, mainly iridoids based on geniposide, carotenoids based on gardenia saffron, and phenolic acids based o...
