Long Chaln Hydrocarbons from Petroleum Ether Fraction of Cestrum fasciculatum (Endl.) Miers. and Eriogonum tomentosum Michx.: Spectral Identification of n-Hentrlacontane and n-Dotrlacontane. : Cestrum

In the course of a continuing search for some certain pharmacological activities of plant origin petroleum ether fraction of alcoholic extracts of Cestrum fasciculatum (Endl.) Miers. and Eriogonun tomentosum Michx. yielded Tong chain hydrocarbons. Among some others two were found in major quantities. These hydrocarbons were n-Hentriacontane (1,2) and n-Dotriacontane (3,4) n-Hentriacontane has been isolated from petroleum ether fraction of Cestrum fasciculatum (Endl.) Miers. by charcoal decolorisation followed by adsorbtion Chromdtography, n-Dotriacontane has been isolated from petroleum ether fraction of Eriogonum tomentosum Michx. with the same procedure. The compounds have been identified with their melting points and spectral properties. For the structure elucidation, ir, nmr, mass spectrometry have been used. In mass spectrometry chemical ionisation method has been applied.
