Abstract
An attempt was made to increase the yield of extraction of ginkgoflavonglycosides from leaves of Ginkgo biloba by treatments of with Cellulase C and macerating enzymes. The yield of dried extract and its contents of ginkgoflavonols, when treated only with cellulase C, were analyzed to be 1. 99% and 0. 38%, respectively. The contents of ginkgoflavonglycosides in the dried extracts were calculated to be 25. 28%. By the treatment with a mixture of three enzymes, cellulase C: cellulase NC and macerosin (1 : 1 : 2), the yield of the dried extract, ginkgoflavonols as well as their glycosides were determined to be 2. 48%, 0. 48% and 24. 16%, respectively.
