Crystal form as inhibitor of ACC1 and ACC2, and preparation method therefor and use thereof

Disclosed is a total flavonoids extract ofKitam., containing 80%-85% of rutin by weight percent content. The results of pharmacological experiments show that the extract can lower the activity of xanthine oxidase in the liver of a hyperuricemia model mouse and reduce the synthesis of uric acid to a certain degree and has a certain uric acid-lowering effect, and can be used as a potential drug for treating hyperuricemia or gout. The method for preparing the total flavonoids extract ofKitam. comprises: after an extraction step, selecting a complex enzyme composed of enzymes with a specific composition and a specific ratio for enzymolosis, and further carrying out the step of extracting and concentrating with macroporous resin and isolating and purifying with macroporous resin, so that the HPLC purity of rutin in the resulting total flavonoids extract ofKitam. reaches 80%-85%.

Total flavonoids extract ofKitam., preparation method therefor and use thereof for treating hyperuricemia

A total flavonoid extract fromKitam., comprising 80-85% of rutin. A preparation method comprises selecting a complex enzyme consisting of a specific composition and ratio of enzymes for enzymatic hydrolysis, extracting and concentrating by a macroporous resin, and separating and purifying by a macroporous resin. The extract has therapeutic effect on non-alcoholic fatty liver disease.
