New technology "digs out" antibiotics from Forsythia

On February 25, an innovative technological breakthrough in the extraction of forsythin from Forsythia suspense was recognized by experts such as sun Handong, academician of the Chinese Academy of Sciences, Yu Dequan, academician of the Chinese Academy of engineering, etc Experts believe that the achievements of forsythin show that the scientific research achievements of Henan biotechnology development center and other units in the research of active ingredients of natural drugs and the application of overall technology have reached the international leading level Traditional Chinese medicine Forsythia has the functions of clearing away heat and detoxification, eliminating swelling and eliminating carbuncle Modern research has proved that Forsythia has excellent antibacterial, antiviral activity, anti-tumor and other functions, which can partially replace antibiotics However, for a long time, traditional Chinese medicine only uses Fructus Forsythiae as medicine, and it is not enough to use the parts containing a large number of effective ingredients, such as leaves of forsythia Researchers from Henan Biotechnology Development Center found that the total amount of forsythin and forsythin in Forsythia leaves was more than 10 times that of fruits Dong Jianjun, a researcher of the center, told reporters that they have carried out a new active combination and optimization of the four effective ingredients of Forsythia suspense, such as phillyrin, forsythin, ursolic acid and flavone glycoside, created an effective geological control method, developed a new active combination product with significant antibacterial effect - 12% forsythin, forming a forsythin with high recovery, low cost, energy saving and emission reduction New extraction process This not only improves the utilization rate of forsythia, but also eliminates the technical barriers of using Forsythia leaves, which paves the way for large-scale utilization of forsythia It is understood that at present, the annual output of antibiotics in China is 210000 tons, of which 97000 tons are used in animal husbandry, and the residues of antibiotics in livestock and poultry products exceed the standard seriously endangering food safety and people's health In October 2011, the 12th Five Year Plan for the development of feed industry issued by China clearly stated that "using plant extracts to reduce the use of antibiotics and other pharmaceutical feed additives" The experimental results of 12% forsythin in broiler show that it can replace the antibiotics such as florfenicol, myxobacillin, monensin and chlortetracycline, and solve the problem of excessive antibiotic residues in livestock and poultry products It can reduce the over dependence of human and animal on antibiotics According to Guo Xinhe, President of Henan Academy of Sciences, Forsythia suspensa is a large-scale medicinal material produced in Henan Province, accounting for 60% of the national total At present, there are about 2 million mu of wild and artificial Forsythia plants in Henan Province The potential value of all Forsythia resources is more than 40 billion yuan based on the value of 2000 yuan of effective components in each mu of forsythia fruit.
