Abstract

The invention discloses an extraction method of a clerodendranthus spicatus total flavone extract. The method comprises the following steps: adding an ethanol aqueous solution with a liquid-material ratio of 5-25 L / Kg and a concentration of 0-95% into a clerodendranthus spicatus powder, performing soaking at room temperature for 1-48h with stirring, performing ultrasonic treatment, filtering the obtained extract liquid, and concentrating filtrate to obtain a paste; and separating the paste with weak-polar macroporous adsorbent resin columns, performing elution with 2-4BV water to remove impurities, performing elution with 2-4BV ethanol with a concentration of 0-95%, collecting ethanol eluent, recovering ethanol under reduced pressure, and performing drying under reduced pressure to obtaintotal flavone extract. The experimental results show that the total flavone extract of the kidney tea can promote serum creatinine and urea nitrogen levels of mice to be obviously reduced, the calciumcontent of kidney tissues to be obviously reduced, and the crystal deposition of calcium oxalate in kidney tissues and the pathological tissue injury of the kidney to be obviously reduced. The clerodendranthus spicatus total flavone extract has effect in preventing or treating urinary calculus, and can be used for preparing medicines, health products or foods for preventing or treating urinary calculus.

Description

technical field [0001] The invention relates to the technical fields of medicine, food and health products, in particular to a method for extracting total flavonoids of kidney tea. Background technique [0002] Urolithiasis, also known as urolithiasis, is the most common disease among urological patients. Stones can occur anywhere in the kidneys, bladder, ureters, and urethra. Clinical symptoms include abdominal and lower back pain, hematuria, frequent urination, urgency, and painful urination, which can cause urinary tract obstruction, urethral injury, hydrops, infection, and impaired renal function. A large number of epidemiological data show that urinary stones are related to many factors such as heredity, age, sex, eating habits, nutritional status, urinary tract infection, environment, metabolic abnormalities, and dyslipidemia. This is a global common disease, and the incidence rate in European and American countries is 5%-12% (Assimos DG. 1089-1090), the number of pa...
