Abstract

The Gingko tea is compounded with gingko extract GBE and tea. The active component GBE is first extracted from grey gingko leaf through resin adsorption process, then produced through concentration and drying into yellowish or brown GBE powder containing total flavone not less than 24% and lactone not less than 5%, and finally produced into 10-20% water solution, which is sprayed onto tea to produce Gingko tea containing GBE in 0.4-1.2% after drying. Being scented and delicious and without side effect, the said Gingko tea has obvious cardio- and cerebro vascular diseases curing effect among others.

Description

A kind of Folium Ginkgo tea and manufacture method

The present invention relates to a kind of Folium Ginkgo tea and manufacture method, particularly a kind of Folium Ginkgo tea and manufacture method that cardiovascular and cerebrovascular disease is had therapeuticing and health effect.

The vessel aging is the key factor that causes the mankind aging and cause various cardiovascular and cerebrovascular diseases.For many years, scientist is by studies have shown that in a large number: Folium Ginkgo extract has blood vessel dilating, blood flow increasing, improve the brain metabolism, remove the effect of free radical and antagonism platelet activating factor, therefore to cardiovascular and cerebrovascular disease, cognitive function disorder, systemic artery hardens, and blood vessel fluidity visual disorder etc. has obvious curative effects." Folium Ginkgo tea and manufacture method " number of patent application 93102087.5 discloses a kind of prescription and manufacture method of Folium Ginkgo tea in the prior art, it is with Folium Ginkgo or the concentrated back of its decocting liquid is direct and Folium Camelliae sinensis mixes, be characterized in adding the Folium Ginkgo of weight ratio 13%, active substance GBE content contained in Folium Ginkgo tea is few, and Folium Ginkgo can influence the stability of active ingredient through processed and storage; Simultaneously, spray 1.5kg Folium Ginkgo water with 10kg Folium Camelliae sinensis and propose liquid, relatively large like this water also can cause big difficulty on tea-manufacturing technology.

For overcoming These characteristics, the invention provides a kind of Folium Ginkgo tea and manufacture method, make in the Folium Ginkgo tea Folium Ginkgo extract GBE content abundant and stable, can reach tangible control health-care effect to cardiovascular and cerebrovascular disease, inexpensive and brew conveniently.

The object of the present invention is achieved like this: Folium Ginkgo tea of the present invention are formed (consumption is a weight portion) by following component:

Folium Ginkgo extract GBE0.4-1.2 part

Folium Camelliae sinensis 80-100 part

The manufacture method of Folium Ginkgo tea of the present invention is: elder generation extracts active ingredient GBE with resin adsorption method from the clean Folium Ginkgo of cinerous, makes to contain total flavones 〉=24%, the light yellow or yellowish-brown GBE powder of lactone 〉=5% behind concentrate drying; Then that this GBE powder is water-soluble, make the solution of 10-20% (W/V), evenly be sprayed in the Folium Camelliae sinensis, dry back Folium Ginkgo tea weight proportion is GBE0.4-1.2 part, Folium Camelliae sinensis 80-100 part.

Folium Ginkgo tea outward appearance and Folium Camelliae sinensis that the present invention makes are just the same, and free from extraneous odour has kept Folium Camelliae sinensis delicate fragrance good to eat, and long-term bubble drink has no side effect, and cardiovascular and cerebrovascular disease is had tangible control health-care effect.

The invention will be further described below in conjunction with embodiment:

1, GBE extracts:

Get the clean Folium Ginkgo 1000g of cinerous that gathers in a year, be broken into coarse powder, add 6-12 60-80% ethanol doubly, reflux, extract, 2-3 time each 1-3 hour, merges ethanol extract, reclaim ethanol, concentrated solution by macroporous adsorbent resin (as DiaionHP-10, HP-50; SP-800, XAD-2 etc.) post adsorbs, and carries out desorbing with 30-80% ethanol then, the ethanolysis imbibition, reclaim ethanol again, concentrated solution is spray-dried, yellowish-brown powder 18g, through assay, qualified after, be spendable GBE.

2, the making of Folium Ginkgo tea:

Get Folium Camelliae sinensis (preferably green tea) 100g, divide in a container, other gets qualified GBE800-1000mg, be dissolved in the 5-10 water doubly, utilize aerosol apparatus, be sprayed at GBE solution on the Folium Camelliae sinensis equably, make its even absorption,, get product in 40-80 ℃ of baking oven inner drying 1-2 hour.
