Embodiment 1

[0054] Cut 20kg carrots into small pieces, chop the aliquots with a blender, then stir and extract with 40L n-pentane and 30L ethyl acetate successively at room temperature for 3 times, and collect the n-pentane extract and ethyl acetate extract respectively , and concentrated under reduced pressure to remove the organic solvent, respectively, to obtain 20g of n-pentane extract (ie: component A) and 15g of ethyl acetate extract (ie: component B). Dissolve component A in 35 mL of a mixed solution of n-pentane and ether (wherein the volume ratio of n-pentane and ether is: 95:5), and pass it through a silica gel column (column diameter 6 cm × height 60 cm, column volume 1.7 L ) separation and purification, the mixed solution of n-pentane and ether is used as the mobile phase to carry out gradient elution according to the following procedure: the volume fraction of n-pentane is respectively 95%, 80%, 70%, 50%, and finally eluted with ether , the above-mentioned mobile phases all e...

Embodiment 2

[0063] 20 kg of medicinal ginseng was crushed, then soaked and extracted with 15 times the volume of 80% ethanol aqueous solution at room temperature for 1 week, extracted twice, combined the extracts, concentrated under reduced pressure to remove the organic solvent, and obtained a concentrate. The concentrate was extracted with 1 volume of n-hexane for three times, the n-hexane layers were combined, concentrated under reduced pressure to remove the organic solvent, and the n-hexane extract was obtained. The n-hexane extract was separated by ODS reverse-phase silica gel column chromatography, and the mixed solution of n-hexane and ethyl acetate was used as the mobile phase to carry out gradient elution according to the following procedure: the volume ratio of n-hexane and ethyl acetate was: 100:1, 70:1, 50:1, 30:1, 10:1, 5:1, the above mobile phases were eluted for 3BV respectively, and the eluents of each mobile phase were collected respectively and concentrated under reduced...

Embodiment 3

[0067] 20kg of the dried root of the medicinal material Gymnaster koraiensis, crushed, soaked and extracted with 15 times the volume of ethanol aqueous solution with a volume concentration of 80% at room temperature for 1 week, extracted twice, combined the extracts, concentrated under reduced pressure to remove the organic solvent; the concentrated solution used 1 volume Double the amount of dichloromethane was extracted for 3 times, the dichloromethane layers were combined, and concentrated under reduced pressure to remove the organic solvent to obtain a concentrate. The concentrate was separated by ODS reverse-phase silica gel column chromatography, and gradient elution was carried out with methanol aqueous solution at 1mL / min according to the following procedure: the volume concentration of methanol was 30%, 60%, and 90%, respectively, and the eluted fractions of each mobile phase were collected respectively. liquid and concentrated under reduced pressure to obtain 3 eluate...

Abstract

The invention belongs to the field of drugs or health care products, and particularly relates to new application of a polyacetylene compound to treating of gout. The polyacetylene compound has a structure shown in a formula (I): R1, R2, R3, and R4 are defined as in the specification. The new application of the polyacetylene compound to treating of gout is found through a hyperuricemia animal model. The polyacetylene compound has the significant effect on lowering the uric acid in a body, and can be used as a potential drug lowering the uric acid or treating gout.

Description

technical field [0001] The invention belongs to the field of medicines or health care products, and in particular relates to a new application of polyacetylenic compounds for treating gout. Background technique [0002] Uric acid is the final metabolite of human purine compounds, and purine metabolism disorders lead to hyperuricemia. Under a normal purine diet, if the blood uric acid level on an empty stomach is higher than 416 μmol / L for men and 360 μmol / L for women on two different days, it is called hyperuricemia. Gout is a crystal-associated arthropathy caused by the deposition of monosodium urate (MSU), which is directly related to hyperuricemia caused by purine metabolic disorders and / or decreased uric acid excretion. The main clinical manifestation is hyperuricemia , recurrent gouty acute arthritis, gouty chronic arthritis and tophi, gouty nephropathy and renal uric acid stones, etc. In severe cases, joint disability and renal insufficiency may occur. In addition, g...
