Spectrophotometry Determination of Total Flavonoids in Peanut Vines

Abstract

Abstract: The ultrasonic method was used to extract falconoid of peanut vines and the total flavonoids were determined by spectrophotometry, the recovery is 95%～106% and the coefficient of variatron is 1.7%. The following regression proved the linearity of the calibration curve: y=0.0118x+0.0106, R2=0.9991. It was found that the content of total flavonoid in peanut vines reaches 2.51%, hence its comprehensive utilization would be very profitable.

Key words: peanut vines, total flavonoids, spectrophotometry, rutin
