Isolation of 2,4,4'-trihydroxydeoxybenzoin and 3'-hydroxydaidzein from soybean miso.
Two 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical-scavenging compounds were isolated from soybean miso. They were determined to be 2,4,4'-trihydroxydeoxybenzoin and 3'-hydroxydaidzein on the basis of spectroscopic data. In the manufacturing process for soybean miso, 2,4,4'-trihydroxydeoxybenzoin appeared during culture aging, and the quantity of it increased in a time-dependent manner.
