Abstract

The invention relates to the technical field of nymphaea candida presl extracts and relates to a nymphaea candida presl total flavonoid extract as well as a preparation method and application thereof. The nymphaea candida presl total flavonoid extract is prepared from the following components in percentage by weight: 50 percent to 80 percent of flavonoid, 1.2 percent to 3.0 percent of isostrictiniin, 9.0 percent to 16.0 percent of nicotiflorin and 4.5 percent to 8.0 percent of astragalin. The invention provides a method for separating and purifying the nymphaea candida presl total flavonoid extract; the flavonoid components are extracted from the nymphaea candida presl by a method with combination of macroporous resin and polyamide resin. The nymphaea candida presl total flavonoid extract has the advantages that the cost is low, the pollution is avoided, and the industrial production is easy to implement; meanwhile, the nymphaea candida presl total flavonoid extract has a good anti-hepatitis effect, is high in effectiveness and low in toxicity, and can be applied to prevention and treatment of liver injury.

Description

technical field [0001] The invention relates to the technical field of water lily flower extract, and relates to a water lily flower total flavonoid extract, a preparation method and application thereof. Background technique [0002] Liver damage caused by various factors such as viruses, alcohol, and drugs is a common clinical disease. Severe or persistent liver damage can lead to liver fibrosis, and even liver cirrhosis, liver cancer and other diseases. Prevention and treatment of liver damage is an important aspect of clinical liver disease treatment. In recent decades, it has become a hot spot in the research and development of drugs for liver disease to search for active parts and active ingredients that can prevent and treat liver damage from traditional Chinese medicine, national medicine and natural medicine. Water lily flower is the dry flower bud of Nymphaea candidaPresl, a plant of the genus Nymphaea. It has the effects of clearing heat, detoxifying, calming and c...
