Abstract: | The periodate oxidation with subsequent alkaline degradation of the products of the oxidation of the predominant saponin isolated fromThalictrum minus has yielded the native genin, which has been called thalicogenin. The structure of thalicogenin as 3 ,16 ,22(S),29-tetrahydroxy-9,19-cyclo-20(S)-lanost-24-ene has been established on the basis of chemical transformations and by spectral methods.Irkutsk Institute of Organic Chemistry, Siberian Branch, Academy of Sciences of the USSR.
