The solvent extraction of total flavonoids from lotus leaf, by single factor experiment of ethanol concentration, extraction time, extraction temperature and solid-liquid ratio on the yield of flavonoids. Orthogonal experiment to determine the best conditions for extraction of total flavonoids: ethanol concentration of 60%, the extraction time 1 h, extraction temperature 70 ℃ and the solid-liquid ratio 1∶60. The study for the extraction process of total flavonoids provides a theoretical basis and technical parameters, to be used in industrial production.
