Abstract：To enhance the utilization rate of the leaves of Camellia longituba Chang.and enrich the plant sources of rutin,the ultrasonic-assisted extraction process of rutin from the leaves of Camellia longituba Chang.was investigated.With the extraction rate of rutin as the measurement indicator,the effects of liquid-solid ratio,methanol volume fraction,ultrasonic temperature,and ultrasonic time on the extraction rate were investigated through single-factor experiments.Based on the results of the single-factor experiments,a Box-Behnken response surface experiment was designed to obtain the optimal extraction process for rutin from the leaves of Camellia longituba Chang..The results indicated that under the conditions of a liquid-solid ratio of 27 mL/g,a methanol volume fraction of 52％,a ultrasonic temperature of 80 ℃,and a ultrasonic time of 63 minutes,the extraction rate of rutin reached its maximum at 6.936 mg/g.Under these conditions,the leaves of Camellia longituba Chang.could be fully utilized.This study not only provides a new approach for the comprehensive utilization of Camellia longituba Chang.leaves but also enriches the plant sources of rutin in industrial production,laying a research foundation for the extraction of total flavonoids from Camellia longituba Chang..
