Optimization of Extraction Process of Catechin in the Cynomorium
OBJECTIVE To optimize the extraction process of catechin in cynomorium. METHODS The orthogonal design method was used to optimize extraction process of catechin in cynomorium which was determined by HPLC as observing index. RESULTS The optimum extracting procedure was as follows: the raw powder of cynomorium extracted with 60% ethanol, with 10 folds of the solvent volume and ultrasonic extract for 30 min. CONCLUSION The optimum extracting process is simple, stable and efficient.
