Discussion on Extraction Process of Volatile Oil from Cangyibiyan Tablets by Uniform Design

Xiong Jingjin

Abstract

Objective: To optimize the extraction process of volatile oil from Cangyibiyan tablets. Methods: Used uniform experimental design,gas chromatography to determine the content of eucalyptol in extraction combined with the extract yield to optimize the best conditions of supercritical CO2 extraction as well as a comparative study with steam distillation. Supercritical CO2 extraction rate was higher than steam distillation extraction method,suitable for extraction of volatile components from Biyan tablets.
