Extracting flavonoid compounds from Toona sinensis leaves

Abstract: Using a method applying alcohol soltion as extraction solvent in cooperation with ultrasonic wave in extraction techniques of flavonoid compounds in Toona sinensis leaves , discussing the primary factors which influences extraction ratio , and analyzing preferable extraction techniques by variance analysis and orthogonal design , the results show that a general extraction ratio reaches 96.47 % after soaking 1.00 g sample in 50 mL 50 % alcoholsolution for 24 h with application of ultrasonic wave for 45 min and repeating again .The extracting ratio of flavonoids is 7.45 %in the leaves and 5.40 % in the leafstalk .The volume percentage of alcohol is a predominant factor for extraction ratio .Application time of ultrasonic wave have certain influence while solvent quantity shows little influence on extraction ratio .
