The invention relates to the technical fields of
medicine, food, beverage, etc., in particular to a method for extracting
propolis containing high-purity flavonoids, that is, a
propolis processing method that ensures low content of
heavy metals, high content of flavonoids, and maintains the "original
flavor" of the product . The invention studies the preparation method of
propolis in a targeted manner, and the obtained propolis extract is safe, low in
toxicity, stable in properties, strong in
pharmacological action, wide in application range, strong in practicability, and remarkable in preventing and health care effects of various diseases. The method has the advantages of low cost, simple preparation process, high yield of active ingredients, high content of
flavonoid extract, and much lower
heavy metals than other methods, especially the lead content is far lower than the
international standard, and the quality of the prepared preparation is stable , easy to operate and more suitable for industrial production. The invention provides a new source of propolis extract, perfects the existing propolis preparation
quality assurance system, and has important value for improving the existing preventive health care level.
