Problems solved by technology

[0003] At present, the treatment of urinary stones, especially kidney stones, mainly uses extracorporeal shock wave lithotripsy (ESWL) and endourological surgery, which often cause kidney damage and serious complications, which can cause renal tissue degeneration and produce glomerulus. Hyalinosis and fibrosis, interstitial congestion, inflammatory cell infiltration, and ESWL and surgical treatment are difficult to cure kidney stones, and the postoperative recurrence rate is about 78% to 80% higher

Embodiment 1

[0065] Embodiment 1: (preparation 1 of kidney tea extract A component)

[0066] The preparation of the kidney tea extract A component is carried out in the following steps:

[0067](1) Grind the dry product of kidney tea [C.spicatus (Thunb.) C.Y.Wu ex H.W.Li] and soak it in methanol for 3 times at the ratio of weight (g): volume (ml) = 1:4, each time After 10 days, the combined extracts were distilled and concentrated under reduced pressure under the control of water temperature at 60°C to obtain the extract mixture;

[0068] (2) Mix the dissolving liquid of step (1) extract mixture and water-methanol by 1:5 volume by weight (g):volume (ml)=1:1 ratio, stir until fully dissolved;

[0069] (3) Extract the liquid extract solution of step (2) 4 times with petroleum ether to fully remove low-polarity impurity components such as resins and chlorophyll, then extract 4 times with ethyl acetate, merge and concentrate the extract;

[0070] (4) The extract in step (3) was subjected to ...

Abstract

The invention discloses a kidney tea anti-urinary calculus extract and a preparation method thereof, and belongs to the technical field of extracts and applications of Chinese herbal medicines. The method comprises: (1) soaking, extracting, and concentrating kidney tea and methanol at a weight: volume ratio of 1:4 to 10 to obtain an extract mixture; 1 proportion mixing and dissolving; (3) Extract the solution with petroleum ether first, then extract with ethyl acetate and concentrate to obtain the extract; (4) Chromatography, elute, collect and concentrate the extract to obtain the kidney tea extract Material A component. It is a fat-soluble flavonoid aglycone compound, which can significantly improve the symptoms of urinary stones, reduce the amount of stones, increase urine output, help stone discharge and anti-inflammatory effects. It can be directly, compounded or further separated and extracted, and can be used for anti-calculus, stone expulsion, diuretic and anti-inflammatory drugs in the urinary system.

Description

【Technical field】 [0001] The invention relates to the technical field of extracts and applications of Chinese herbal medicines, in particular to an extract of kidney tea for resisting urinary calculus and a preparation method thereof. 【Background technique】 [0002] Kidney stones, bladder stones, urinary calculi, etc. are common diseases of the urinary system. It is reported in the literature that the incidence is 5% to 9% in Europe, 12% in Canada, about 13% in the United States, and about 9% to 15% in my country. The incidence of urinary stones is as high as 20%. The incidence increases with age, and the risk also increases. Areas with hotter climates and people who eat animal protein, especially young and middle-aged men aged 30 to 50, have a higher incidence rate, with a male to female ratio of 2 to 3:1. Epidemiological surveys in recent years have shown that the incidence rate is on the rise, especially among young and middle-aged people, which has seriously affected pe...
