Chemical examination of the seeds ofDodonaea viscosa

Summary and Conclusion

• 1. From the seeds ofDodonœa 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.
