Problems solved by technology

There are four main reasons for the accumulation of uric acid: the first is excessive consumption of high-purine foods; the second is a problem with purine metabolism in the body; the third is too little excretion; the fourth is that uric acid cannot be excreted normally
[0011] In the prior art, there is no report on the use of kaempferin for reducing uric acid

Abstract

The invention relates to the technical field of plant extraction, and particularly relates to a method for extracting apigenin from Ostericum sieboldii and application. The method comprises the stepsof (1) drying and smashing Ostericum sieboldii, adding a solvent A for extraction, and concentrating an extracting solution to obtain a substance A; (2) extracting the substance A with a solvent B, and drying an extracted solvent B layer to obtain a crude product; (3) dissolving the crude product with a solvent C, adsorbing with macroporous adsorption resin, and eluting with a solvent D to obtainan eluent; and (4) concentrating and crystallizing the eluent to obtain the product. The method has the advantages that the yield and the purity are high, and the effect of reducing uric acid is remarkable by combining the apigenin with other effective components for use.

Description

technical field [0001] The invention relates to the technical field of plant extraction, in particular to a method for extracting apigenin from celery and its application. Background technique [0002] Celery is a perennial herb of Umbelliferae and the genus Celery. Celery has both medicinal and edible value. Shanqin has the effects of mainly treating rheumatic arthralgia, soreness of the waist and knees, cold headache, carbuncle sores, swelling and pain. Celery is a high-grade rare vegetable in celery. The nutrient content of wild celery is also higher in wild vegetables, and the seedlings of wild celery can be used as wild vegetables in spring. Its nutritional effects are as follows: (1) Celery has high iron content, which can supplement the loss of women's menstrual blood. Eating it can prevent pale, dry and dull complexion, and can make eyes bright and hair black and shiny. (2) Celery is a high-fiber food. It produces a lignin or intestinal fat substance through intes...
