Flavonoids have very important medical value. They have many functions, such as anti-inflammatory and anti-tumor virus. They mainly come from the photosynthesis of plants, so they can extract flavonoids from plants, such as clover. The material structure and physical properties of flavonoids were analyzed. The extraction methods of flavonoids were discussed. Finally, the extraction process of total flavonoids from Trifolium repens was studied by using ethanol as solvent. The optimum extraction technology of single factor experiments and orthogonal experiment optimization of total flavonoids from Radix Tetrastigmae was 60% ethanol concentration, the extraction time is 1.5 hours, and the suitable process conditions in this optimization, which can get higher flavonoids extraction and purification rate, thereby improving the production efficiency of flavonoids.
