  • Patent number: 11298390
    Abstract: Disclosed is a total flavonoids extract of Gynura formosana Kitam., 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 of Gynura formosana Kitam. 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 of Gynura formosana Kitam. reaches 80%-85%.

  • Publication number: 20150224106
    Abstract: A method of treating a patient to improve liver functioning includes providing a drug composed of at least one of pharmaceutical 2-(4-morpholinoaniline)-6-cyclohexyl aminopurine and a salt thereof; and administering the drug to the patient in a manner and dosage effective to improve liver functioning. The 2-(4-morpholinoaniline)-6-cyclohexyl aminopurine can inhibit the activated hepatic stellate cells from synthesizing and expressing collagens and other extracellular matrix proteins including MMPs and TIMPs, and so it can inhibit liver fibrosis. In the liver, it can inhibit collagen synthesis and expression, and therefore reverse and treat hepatitis and liver cirrhosis effectively.
