[Experimental studies on compound Duzhong Jiangya prescription by semi-bionic extraction].

Objective: Optimize the technic condition of Duzhong Jiangya prescription with Semi-bionic Extraction.

Method: Using homogeneous design, under the same materials granularity, decoction temperature, consumption of water, filtration, concentration, and taking aucubin, hydrochloric acid stachydrine, maloicacid, baicalin, ethanol extract, dry extract as the indexes, the results were comprehensive considered to optimize the semi-bionic extraction condtions.

Result: The optimized SBE extraction conditions are the following: pH values of the water for the thrice extraction is 5.

[Optimizing the best extraction condition of semi-bionic extraction for licorice by unifrom design].

Objective: To optimize the best extraction condition of semi-bionic extraction for licorice.

Methods: The best extraction condition of the semi-bionic extraction for licorice by uniform design was optimized with glycyrrhizic acid, total flavonoids, total polysaccharides, total HPLC integrate area and dried extract weight as the indexes.

Results: The optimized technologic condition: The pH values of the water for the 1st, 2nd, and 3rd decoctions were in order of 5.
