Studies on biochemical transformation of plant steroids. Part IV. Biosynthesis of 3α-hydroxylated steroidal sapogenins. Part I
Abstract
[1-3H]Diosgenin (VI), [1-3H]diosgenone (VII), [1-3H]smilagenone (X), [1-3H]smilagenin (VIII), and [1-3H]-epismilagenin (IX) were incubated with the homogenate from Dioscorea tokoro seedlings at 27–29° for 7 h. The results indicate that epismilagenin is a most important precursor in the biosynthesis of 3α-hydroxylated steroidal sapogenins.
