Results: Purity of 73.

[Study on isolation of Chlorogenic acid from Eucommia ulmoides leaves by ultrafiltration technique].

Objective: To isolate and purify Chlorogenic acid from Eucommia ulmoides leaves by ultrafiltration technique.

Methods: Chlorogenic acid transferring ratio was investigated by temperature, pressure, time, cut-off molecular mass.

Results: The optimal conditions for the ultrafiltration technique were finally determined.

[Study on the technique of ultrasonic wave extraction of triterpeneclucoside].

The extraction technique of ultrasonic wave on increasing the triterpeneclucoside was studied. Based on single factor experiments and the orthogonal design introduced,the optimized extracting conditions of triterpeneclucoside were investigated. The results showed that the best extraction technique conditons are 65% alcohol-water, the ratio of solid to liquid 1:30,dousing over 30 minutes,ultrasonic wave lasting for 40 minutes, ultrasonic frequency 26.
