Abstract: The content of total flavonoids in white flesh loquat leaves and its extraction technology were studied in research. By means of the methods of ethanol-extracting, the optimum extraction conditions of flavonoids in white flesh loquat leaves were determined. The results showed that the content of total flavonoids in white flesh loquat leaves was 0.5642%, the optimum conditions of ethanol-extracting were obtained as follows: 70% ethanol as extraction solvent at 60 ℃ for 2.5 h, and the ratio of material to solvent was 1:50. This data provided useful pharmaceutic in formation of flavonoids from white flesh loquat leaves.
Key words: white flesh loquat leaves, flavonoid, extraction technology
