NEW MATERIAL:Tetrahydro-1-[ 3-methoxy-4-hydroxyphenoxy ] -4- [ 3,4-(methylenedioxy)phenyl]-1H,3H-furo[3,4-c]furane. USE:Antioxidant: it has high safety. PREPARATION:beta-Glucosidase or a microorganism such as Bacillus Natto or Rhizopus oligosporus is made to act on sesami seeds, defatted sesami seeds or their extract to give the compound of formula I . When the substrate is treated with the enzyme, the extract is dissolved or suspended in water, sterilized by cell filtration or with humid heat and kept at such a temperature and a pH as beta-glucosidase can easily develop its action (usually pH 3-7 and 30-65 deg.C). On treatment with the microorganism, the extract is combined with water, sterilized, when necessary, adjusted in pH to 4-7, then the microorganism is inoculated and cultured. |
