Embodiment 1

[0017] Embodiment 1 acute toxicity test

[0018] Due to the limitation of administration concentration and administration volume, the LD50 of intragastric administration to mice could not be measured, and the water suspension, water extract, ethanol extract, and methanol extract of compound sequence Ligwu herb were pulverized at 90ml / kg dose was given to mice for intragastric administration, the animals were in good condition, and no acute toxic reaction was seen. The maximum dose of intragastric administration for mice in one day was ≥ 90ml (four kinds of extracts were respectively equivalent to crude drug amounts of 95.5g / kg, 110.5g / kg, 130.0g / kg, 135.0g / kg).

Embodiment 2

[0019] Example 2: The application of Ligularia complex to prepare uric acid-lowering products

[0020] 1. Ligularia jaluensis capsule (LJC): collect Ligularia jaluensis, dry in the shade, crush to make a hard capsule preparation.

[0021] 2. Ligularia jaluensis tablet (LJT): Collect Ligularia jaluensis, dry in the shade, pulverize, ultrasonically extract with 10 times the amount of 75% ethanol three times, each time for 30 minutes, filter, combine the filtrates, and evaporate to dryness , pulverize, add appropriate amount of starch, and press into tablets.

[0022] 3. Ligularia jaluensis oral liquid (LJOL): take Ligularia jaluensis oral liquid, decoct in 10 times the amount of water for 40 minutes, filter, concentrate the filtrate to obtain liquid extract, add auxiliary materials, and make oral liquid .

Abstract

The invention relates to application of Ligularia jaluensis in preparation of xanthine oxidase inhibitors, and belongs to the field of traditional Chinese medicine. The invention discloses use of Ligularia jaluensis and an extract thereof as active components in the preparation of the xanthine oxidase inhibitors, wherein the Ligularia jaluensis and the extract thereof comprise a Ligularia jaluensis original plant and a solvent extract thereof, and the solvent extract comprises water, ethanol and methanol extracts. The application has the beneficial effects that the problem of abnormal blood uric acid rise of related diseases such as hyperuricemia and arthrolithiasis is solved, and arthralgia and swelling distortion caused by the diseases such as hyperuricemia and uarthritis as well as related symptoms for the diseases such as hypertension, diabetes, cardiovascular diseases, kidney diseases and metabolic syndrome are indirectly solved and relieved.

Description

technical field [0001] The invention relates to the field of traditional Chinese medicine, in particular to a xanthine oxidase inhibitor derived from traditional Chinese medicine. Background technique [0002] If the uric acid level in the body continues to be high and supersaturated, sodium urate crystals will be deposited in the joints and surrounding tissues, resulting in gout, a purine metabolic disease. Hyperuricemia is an important sign of gout. About 5% to 12% of hyperuricemia will eventually develop into gout, and 80% to 90% of gout patients are accompanied by hyperuricemia. In addition, hyperuricemia is also closely related to the occurrence of hypertension, diabetes, cardiovascular disease, kidney disease, metabolic syndrome and other diseases. The incidence of gout varies greatly between regions. Its incidence is only 0.03% in Nigeria, but as high as 15.2% among the aborigines of Taiwan. Epidemiological surveys show that due to the improvement of people's living...
