Chemical examination of the essential oil of Artemesia scoparia Waldst and Kit

Abstract

1. From the green herb and the flowering heads of Artemesia scoparia an essential oil and a fixed oil have been obtained in yields of 0.75 per cent. and 4.45 per cent. respectively. 2. 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%). 3. 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.
