Study to Evaluate the Effectiveness and Quality of Products of The Process of Extracting Codonopsis javanica Extract at Pilot Scale

Abstract

The Codonopsis javanica, also known as “Đảng sâm” in Vietnamese, is a medicinal plant of high economic value. In this study, we further extended the previously reported process to produce C. javanica root extract by examining the concentrating stage to produce dried extract. Afterwards, effects of storage conditions on were evaluated and the pilot scale extraction process was compared with the lab-scale process. These processes were investigated with respect to different extract quality parameters including total polyphenol content (TPC), total flavonoid content (TFC), DPPH and ABTS scavenging activity. Best conditions for the concentration process included time of 120 minutes, temperature of 60°C. The efficiency of extracting C. javanica extract at pilot scale shows a difference of about 20% and this dried extract will retain the best quality when stored at 5°.
