Embodiment 1
[0025] The preparation of embodiment 1 vine tea extract:
[0026] 1000g rattan tea coarse powder, containing 19.52% of total flavonoids, 16.46% of dihydromyricetin content, adding 20L water extract (containing 0.05% L-cysteine in the water extract, and adjusting the pH to 2.5 with hydrochloric acid), impregnated After half an hour, heat to boiling and maintain for half an hour. Filter through a 20-mesh sieve, add 100ml of polyacrylamide 4350 (cationic type) aqueous solution with a concentration of 0.1% to the filtrate, stir for 1 minute and then let it stand for half an hour, the flocs precipitate and filter through an 80-mesh sieve to obtain the clear liquid of the vine tea water extract. The supernatant liquid of the water extract is heated and vacuum-concentrated to half of the original volume, cooled to 2-4°C, and left to allow the vine tea extract to crystallize. The crystals were collected by filtration, rinsed with deionized water three times the weight at the same t...

Abstract
The invention provides a vine tea extract which is prepared by the following steps: adding a flavones protective agent into an aqueous solution during water extraction of the vine tea; heating and filtering; adding a co-precipitator into the filtrate for flocculation and sedimentation; and after filtering the precipitate, freezing the filtrate to crystallize and separate out the vine tea extract, wherein the vine tea extract comprises 80-90% of general flavones and 70-80% of dihydromyricetin based on general flavones. The invention further provides a composition which comprises the vine tea extract and a ginkgol biloba extract as well as an application of the composition in preparing foods, health foods and drugs for preventing and treating geriatric cognitive disorders. The invention further provides an application of the vine tea extract in preparing drugs for inhibiting prostatic hyperplasia and treating benign prostatic hyperplasia, as well as foods, health foods and drugs for reducing blood sugar, blood fat and blood pressure. Compared with the extract prepared by the existing method, the extract provided by the invention is improved in purity and white in luster. Clinical applications show that the vine tea extract has a certain function of improving getting up in the night to urinate. The vine tea extract combined with the ginkgo biloba extract can be used for preventing and improving geriatric cognitive disorders.
