• 論文の詳細を見る

• Kitigenin has its four hydroxyl groups all on ring A. One of them is a tertiary, C_5-hydroxyl group, since it resists oxidation and acetylation. Subsequently, kitigenin was converted to 4-hydroxy-25D-spirost-4-en-3-one and 25D-spirostan-3β, 4ξ, 5ξ-triol, synthesized from diosgenone. Therefore, it was determined that the three hydroxyl groups are located at C_3,C_4,and C_5 and that the configuration of the C_3-hydroxyl group is β and the C_4- and C_5-hydroxyl groups are in cis relation.
