Objective: To discuss the feasibility on habitat processes method of Sophora flavescons. Method: The water content of medicinal parts of S.flavescens was determined under the different dry conditions

and then the quantities were evaluated in different pieces by comparing the content of water soluble extraction

matrine and oxymatrine accordance with the 'Chinese Pharmacopoeia’. Result: It is more convenient for processing when the water content of medicinal parts was at 45%-40%. At the same times

the content of extraction and active ingredients were close to traditional pieces. Conclusion: Habitat processing method could not only shorten the soften time in processing

but also save the cost of production to ensure quality of pieces. It is a new processing method for modern scale and standardized production of Chinese herbal pieces

and can be widely used in similar Chinese herbs.
