Description
Technical field
The present invention relates to pharmaceutical technology field, in particular to a kind of Hickory Leaves extract with anti-trioxypurine effect is always yellow
Ketone as well as preparation method and application thereof.
Background technique
Uric acid is the metabolite of purine in endogenous purine and diet.In the purine metabolism of human body, ATP etc. passes through one
The metabolic response of series, produces hypoxanthine and xanthine, and the two generates uric acid under xanthine oxidase effect.When purine generation
When thanking to disorder, serum uric acid level is excessively high, leads to the generation of hyperuricemia (Hyperuricemia), then uric acid is caused to be saltoutd
Joint is crystallized and be deposited in out, gout is caused to be broken out, and is often involved kidney and is caused arteriosclerotic kidney and uric acid kidney stones, and
And it may cause Metabolic syndrome and seek peace relevant cardiovascular disease.In recent years, the disease incidence of hyperuricemia sharply increases, and has surpassed
10% is crossed, one of big chronic disease of 21 century 20 is classified as by the United Nations.
Prevention and treatment hyperuricemia class drug is broadly divided into uric acid and generates depressant (such as Allopurinol) and uricosuric excretion at present
Two kinds of medicine (such as Benzbromarone), although these drugs have apparent anti-trioxypurine to act on, side effect is also larger, such as fash, hair
Heat, hepatic renal dysfunction etc., thus the range limited its application.Therefore, developmental research drug effect is clear and the novel of safety resists
Antihyperuricemic disease drug is very necessary.According to the literature, inhibit in natural plant crude drugs source containing a large amount of xanthine oxidases
The ingredient of agent and uricosuric excretion, and small toxicity, it is highly-safe, there is preferable research and development prospect.
Chinese walnut (Carya cathayensis Sarg.) is Juglandaceae hickory plant, Hickory Leaves frequently as
Folk tradition Chinese herbal medicine, for the purposes such as clearing heat and detoxicating, existing research shows that Hickory Leaves extract contains a large amount of anti-oxidant work
Property substance, predominantly Flavonoid substances, have apparent anti-aging, antitumor, anti-angiogenesis and other effects.Currently, there is not yet
To the relevant report using Hickory Leaves extractive total flavone treatment hyperuricemia.Inventors discovered through research that hickory nut
Leaf extract pinostrobin can reduce rat model serum uric acid level, can be used for preventing and treating the drug that hyperuricemia is major function
And health food.
Summary of the invention
The purpose of the present invention is to provide a kind of Hickory Leaves extractive total flavones with anti-trioxypurine effect, provide simultaneously
