Increase of Aurantio-Obtusin Content in Cassiae Semen by the Treatment of Crude Enzyme Extract from Aspergillus kawachii

Abstract

“Suchi“, a kind of processing technique, have been used for reducing toxicity or changing medicinal efficacy of oriental crude drugs. The techniques, however, are rarely used nowadays due to their complexity and lack of scientific backgrounds. On the other hand, food processing techniques such as heating, extrusion, and enzyme treatment (fermentation) might be applied to oriental crude drugs in order to increase the contents and/or to change the chemical structure of biologically active compounds.
