Study of Extraction Technology for Volatile Oil from GANDAKANG

Chenggang Liu

Abstract

Objective To optimize the extraction process of volatile oil in GANDAKANG. Methods The optimum extraction process was selected by the L9(34) orthogonal design,using the recovery rate of volatile oil as indicator. Results The optimized extraction process was as follows:medicinal materials were distilled for 4 h with vapor,soaked in 6 times water for 30 minutes. Conclusion The process is feasible and useful for the actual production.
