Chemical examination of the seeds of Dodonaea viscosa. Isolation of dodonin, dodogenin and a fixed oil

Abstract

1. From the seeds of Dodonoea viscosa a glucoside (M.P. 182-86°C.) and a fixed oil have been obtained in yields of 3.42 and 20.27 per cent. respectively. 2. The glucoside and the product of its hydrolysis have been named "Dodonin" and "Dodogenin" respectively. 3. "Dodogenin" which has a molecular formula C₂₃H₃₆O₈ melts at 249°C. and contains a cyclo-penteno-phenanthrene nucleus in its molecule. In general properties it resembles the Sapogenins. 4. A number of derivatives of "Dodogenin" have been prepared and examined.
