Abstract: Peanut vines are rich in flavonoids compounds. Flavonoids in peanut vines were determined by spectrometric metnod with rutin as a standard in this study. Flavonoids from peanut vines of various organs were prepared according to L9(34) orthogonal tests plan. The relationship between extracting conditions and yield of flavonoids extracted form peanut vines was investigated. The results showed that the optimum extracting conditions are: ethanol concentration 60%, temperature of extraction 65 ℃, solid-liquid ratio 1 g:40 ml and uitrasonic wave time 20 min

Key words: peanut vines, spectometric method, total flavonoids, ultrasonic wave, extracting technology
