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 ...

Embodiment 2

[0071] Embodiment 2: (preparation 2 of kidney tea extract A component)

[0072] In this preparation example, the dry product of kidney tea is pulverized and soaked in methanol at a ratio of weight (g): volume (ml) = 1:7; the combined extracts are concentrated by vacuum distillation under the control of water temperature at 50°C; water- Methanol was mixed at a volume of 1:9 to form a solution; chromatography, elution, and collection were concentrated by vacuum distillation under the control of water temperature at 50°C, and the rest of the preparation steps and process conditions were the same as in Example 1.

Embodiment 3

[0073] Embodiment 3: (preparation 3 of kidney tea extract A component)

[0074] In this preparation example, the dry product of kidney tea is pulverized and soaked in methanol at a ratio of weight (g): volume (ml) = 1:10; the combined extracts are concentrated by vacuum distillation under the control of water temperature at 40°C; water- Methanol was mixed at a volume of 1:12 to form a solution; chromatography, elution, and collection were concentrated by vacuum distillation under the control of water temperature at 40°C, and the rest of the preparation steps and process conditions were the same as in Example 1.

Abstract

The present invention discloses a clerodendranthus spicatus extract for resisting urinary lithiasis and its preparation method, belonging to the field of Chinese medicinal material extract and application technology. Said method includes the following steps: (1), soaking the cleodendranthus spicatus and methyl alcohol according to the ratio of weight:volume=1:4-10, extracting and concentrating so as to obtain extract mixture; (2), mixing said extract mixture and dissolving liquor according to the ratio of weight:volume=1:1 and dissolving; (3), firstly, using petroleum ether to extract said dissolved liquor, then using ethyl acetate to make secondary extraction, concentrating to obtain extract; and (4), making the above-mentioned obtained extract undergo the processes of chromatography, elution, collection and concentration so as to obtain the invented cleodendranthus spicatus extract component A. Said component A belongs to a fat-soluble flavone aglucone compound which can be used for preparing the medicine with the excellent effect for improving litholysis, promoting lithecbole, diuresis and relieving inflammation, etc.

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...
