Problems solved by technology

However, the treatment of gout mainly relies on uricosuric drugs (such as probenecid, benzbromarone, etc.) and xanthine oxidase inhibitors (such as allopurinol, febuxol, etc.) Tan), very limited, and traditional uricosuric drugs are often accompanied by side effects such as rash, fever, and kidney damage, while xanthine oxidase inhibitor allopurinol is the most commonly used xanthine oxidase inhibitor in clinical practice. It also has adverse reactions such as liver and bone marrow toxicity and allergies, which limits its safe use to a certain extent; febuxostat is a new drug approved by the US FDA in 2009, with good curative effect, but the long-term effects and side effects still need to be further developed Observed

Embodiment 1

[0017] Get fresh mangosteen peel 50kg, soak 4 times with 100L of 95% ethanol, each 48 hours. The soaking liquids were combined, concentrated under reduced pressure at 50°C until there was no ethanol smell, left overnight (12 hours), filtered to obtain 1.98kg of filter residue (17L of dark reddish-brown filtrate for later use), added 20kg of water, stirred to suspend, filtered, and vacuum-dried at 60°C , pulverized to obtain yellow-brown powder 1.38kg (mangosteen extract I).

[0018] Take the above spare dark reddish-brown filtrate, extract 3 times with chloroform, 6L each time, apply macroporous adsorption resin (resin 20kg, chromatographic column diameter 20cm, column volume is 35L) on the aqueous solution after extraction, first use 3 times The column volume was eluted with water, and then eluted with 75% ethanol solution for 3 times the column volume, the eluate was collected, concentrated under reduced pressure at 50°C, dried under vacuum at 60°C, and pulverized to obtain ...

Embodiment 2

[0022] Take 20 kg of dried mangosteen peel, crush it, pass through a 10-mesh sieve, add 40 L of 50% ethanol, soak for 48 hours, 2 times in total, filter; then soak in 80 L of ethanol for 48 hours, 2 times in total, filter; combine 4 extracts, Concentrate under reduced pressure at 50°C until there is no ethanol smell, place overnight (12 hours), filter to obtain 2.28kg of filter residue (36L of dark reddish-brown filtrate for later use), add 23kg of water, stir to suspend, filter, vacuum-dry at 60°C, and pulverize to obtain Yellow-brown powder 1.62kg (mangosteen extract I).

[0023] Take the above spare dark reddish-brown filtrate, extract 3 times with chloroform, 12L each time, apply macroporous adsorption resin (resin 20kg, chromatographic column diameter 20cm, column volume is 35L) on the aqueous liquid after extraction, first use 3 times The column volume was eluted with water, and then eluted with 75% ethanol solution for 3 times the column volume, the eluate was collected...

Embodiment 3

[0026] Healthy male Kunming mice (body weight 18-22g) were provided by Beijing Huafukang Biotechnology Co., Ltd., certificate number: SCXK (Beijing) 2014-0004. Animals were randomly divided into normal control group, hyperuricemia model group, fresh mangosteen peel extract I and II groups (20.0 mg / kg each) and positive control group allopurinol 5 mg / kg. The test compound was formulated with 0.5% sodium carboxymethylcellulose (0.5% CMC-Na) to an appropriate concentration, administered orally, twice a day, 5 doses in total. Reference [HallIH, Scoville JP, Reynolds DJ, Simlot R, Duncan P.Substituted cyclic imides aspotencial anti-gout agents.Life Sciences.1990, 46:923-1927.Stavric B, ClaymanS, Gradd REA, Hebert D.Some in vivo effects in the rat induced by chlorprothixene and potassium oxonate Pharmacology Research, 1975, 7: 117-124] using uricase inhibitor potassium oxonate as a chemical inducer, intraperitoneal injection of potassium oxonate 400mg / kg, resulting in hyperuricemia ...

Abstract

The invention relates to Garcinia mangostana L. fruit pericarp extract for treatment of gout and a preparation method thereof. The preparation method includes the following steps: using Garcinia mangostana L. fruit pericarp as a raw material, and carrying out extracting, concentrating and enriching on the Garcinia mangostana L. fruit pericarp, so at to obtain the Garcinia mangostana L. fruit pericarp extract for treatment of gout. Studies show that Garcinia mangostana L. fruit pericarp extract I and II have a strong uric acid-reducing effect, the uric acid level in serum of hyperuricemia miceinduced by oteracil potassium can be significantly reduced by intragastric administration of the Garcinia mangostana L. fruit pericarp extract I (20 mg / kg) or II (20 mg / kg); and fresh garcinia Mangostana L. fruit pericarp extract I and II and dried Garcinia Mangostana L. fruit pericarp extract I and II can significantly reduce the serum uric acid levels. In vitro studies show that the mechanism ofuric acid reducing action of the Garcinia mangostana L. fruit pericarp extract II is related to inhibition of uric acid production, while the mechanism of uric acid reducing action of the Garcinia mangostana L. fruit pericarp extract I is related to promotion of uric acid excretion. Obvious toxic and side effects and animal deaths are not observed in mice after intragastric administration of theGarcinia mangostana L. fruit pericarp extract I (5.0 g / kg) and II (5.0 g / kg), respectively. Therefore, both the Garcinia mangostana L. fruit pericarp extract I and II can be used to prepare oral drugsand health products to resist gout and hyperuricemia and to treat diseases related to hyperuricemia.
