Description

Efficacy-enhanced artemisia selengensis leaf uric acid-reducing beverage
Technical Field
The invention relates to an efficacy-enhanced artemisia selengensis leaf uric acid-reducing beverage.
Background
With the development of economic society of China, the dietary demands and the quality of life of people are continuously improved, and meanwhile, the working pressure is gradually increased, and hyperuricemia becomes an invisible killer threatening the health of people. In recent years, the prevalence of hyperuricemia has increased year by year, and the average age of the affected population has exhibited a decreasing trend. The data show that nearly 10% of patients with hyperuricemia suffer from gout, and therefore, it is critical to prevent and treat gout to avoid uric acid accumulation.
Modern medicine considers that the kidney is the main place for generating human urine (uric acid), and hyperuricemia is caused by the increase of uric acid production in a human body and the reduction of uric acid secretion of the kidney, so that gout is directly induced. At present, medicines are generally used for reducing the concentration of uric acid in blood so as to prevent gout, such as allopurinol, febuxostat and the like, but the medicines have certain defects in treatment, have the effects of treating symptoms and root causes but not treating the root causes, have large side effects, even cause or aggravate kidney injury, and are not beneficial to long-term application in reducing uric acid or preventing uric acid increase. Therefore, the research and development of the uric acid-reducing health/functional food which is natural in source, safe and effective and can treat both symptoms and root causes has important social and economic significance.
Artemisia Selengensis Turcz (Artemisia Selengensis Turcz) which is also called Artemisia Selengensis and Artemisia betel, is perennial herb of Artemisia in Compositae, has a long history of eating, the main eating part of the Artemisia Selengensis is tender stem, and a large amount of Artemisia Selengensis leaves cannot be eaten due to bitter taste and excessive discard. Researches show that the artemisia selengensis leaves are rich in flavonoids, have the activities of regulating purine metabolism key enzymes and reducing the concentration of blood uric acid, have great potential for developing anti-gout products, but the efficacy of the existing artemisia selengensis leaf beverage is still required to be further improved.
Disclosure of Invention
In order to overcome the defects of the prior art, the invention screens and obtains the artemisia selengensis leaf uric acid reducing beverage with enhanced efficacy by taking natural medicinal botanics as a basis and combining a modern pharmacological pharmacodynamics research method, the uric acid reducing efficacy of the artemisia selengensis leaf is further improved by adding four plant extracts of common selfheal fruit-spike, rose, spina date seed and dahurian angelica root, and meanwhile, the beverage has good kidney protection efficacy and is more beneficial to the recovery and prevention of gout and hyperuricemia.
In order to achieve the purpose, the applicant finally obtains a formulation of the artemisia selengensis leaf uric acid reducing beverage with enhanced efficacy by screening a large number of experiments according to the previous research results of the applicant, wherein the beverage takes artemisia selengensis leaf extracting solution as a main component, and the efficacy of the beverage is enhanced by adding a small amount of prunella vulgaris, rose, spina date seed and radix angelicae extract, and the formulation is specifically as follows:
a artemisia selengensis leaf uric acid reducing beverage with enhanced efficacy comprises an artemisia selengensis leaf extracting solution and four extracts which respectively account for the following mass percentages of the artemisia selengensis leaf extracting solution:
Figure BDA0003530939760000021
the four extracts are added, so that the artemisia selengensis leaves have stronger Xanthine Oxidase (XOD) inhibition activity, and the detection of the in vitro enzyme activity and the XOD activity in the liver of an animal shows that compared with the artemisia selengensis leaves beverage without the extracts, the XOD enzyme inhibition activity of the invention is obviously increased, so that the invention is more beneficial to reducing uric acid, and simultaneously, the invention can also reduce the serum creatinine (Cr) and urea nitrogen (BUN) contents of a hyperuricemia mouse, which prompts that the invention also has a certain kidney protection effect, and is more beneficial to the recovery and prevention of gout and hyperuricemia.
Research finds that the exertion of the above effects is closely related to the mixture ratio of the four extracts, which indicates that certain interaction exists among the four extracts, and when the four extracts are respectively added according to the following mixture ratios, the XOD enzyme inhibitory activity and the kidney protection effect are relatively better:
Figure BDA0003530939760000022
preferably, the beverage also contains the following auxiliary materials in percentage by mass in the artemisia selengensis leaf extracting solution:
7-15% of xylitol
0.05 to 0.13 percent of citric acid
0.2-1% of beta-cyclodextrin.
Further preferably, the auxiliary materials respectively account for the mass percentages of the artemisia selengensis leaf extracting solution as follows:
13 percent of xylitol
0.09 percent of citric acid
Beta-cyclodextrin 0.6%.
Further preferably, the preparation method of the chenopodium album leaf extract comprises the following steps: drying fresh artemisia selengensis leaves at 60 ℃ for 10h, then crushing, adding water according to the mass-to-volume ratio of 1:40 of material liquid, leaching at 95 ℃ for 40min, and filtering to obtain artemisia selengensis leaf extracting solution.
The invention has the beneficial effects that:
(1) the drink provided by the invention has excellent XOD (X-ray diffraction) inhibition activity in vitro, has the effect of obviously reducing blood uric acid in vivo, and has stronger effect compared with the existing chenopodium album leaves, so that the synthesis of uric acid in vivo can be better inhibited. Meanwhile, the invention can also reduce the renal function damage caused by hyperuricemia and show the protective effect on the kidney, thereby being more beneficial to the recovery and prevention of diseases.
(2) The raw materials used in the invention have natural and healthy components, low cost, good sensory quality, safety and effectiveness, and are suitable for being developed into health-care or functional foods for people with high uric acid and people with high risk of high uric acid to drink for a long time.

The effect on serum creatinine (Cr) and urea nitrogen (BUN) content in uric acid-rich mice is shown in table 3. Creatinine and urea nitrogen in serum are metabolized through the kidney, the two index results are generally used for representing the influence and damage of substances on the mouse kidney function clinically, and the increase of serum creatinine and urea nitrogen indicates the damage of the kidney function. Compared with the model control group, the serum creatinine value and the serum urea nitrogen value of the mice in the group of the example 1 are obviously reduced, which indicates that the mice have the effect of protecting the kidney. And the effect of example 1 is more remarkable than that of the other examples.
