概要
- 論文の詳細を見る
From the examination of yields of sapogenins isolated from Hosta kiyosumiensis F. MAEK in each season, it was assumed that gitogenin is oxidized to the 12-oxygenated sapogenins in the hypogeous part of the plant in winter. In order to confirm this assumption, [27-^<14>C]-gitogenin was incubated with the homogenate from the hypogeous part of the plant at 37°for 6 hr. The result from this experiment indicates the conversion of gitogenin into the 12-oxygenated sapogenins by the action of the plant enzyme.
