From the bark of
The alkaloid has been found to be a monoacid base containing one methoxy group but no >N−CH3 group.
The alkaloid which is dextrorotatory easily gives crystalline salts with organic and inorganic acids and the hydrochloride, sulphate, nitrate, iodide, acetate, tartrate, oxalate, picrate and iodomethylate have been prepared and described.
Volume 25 Issue 2 February 1947 pp 153-158
From the flowering heads and seeds of
The lactone, which has been named “Scoparin”, has been found to have the molecular formula C16H20O5. It contains an α: β-unsaturation, one ketonic group and two methoxyl groups.
A number of derivatives of the lactone have been prepared and analysed.
Volume 26 Issue 1 July 1947 pp 56-60
From the seeds of
The glucoside and the product of its hydrolysis have been named “Dodonin” and “Dodogenin” respectively.
“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.
A number of derivatives of “Dodogenin” have been prepared and examined.

From the green herb and the flowering heads of
The essential oil was found to contain eugenol (8.96%), a sesqueterpene (79·44%), a hydrocarbon (2·63%), and residue mainly containing the decomposed products (8·97%).
The sesqueterpene, which has a molecular formula C15H24 has been named “Scoparilene”. It has been found to be different from any known sesqueterpene. Its nitrosate and nitrosite have been prepared and described.
