Chemical Composition from Cucumis prophetarum L

Ermias Tamiru, Welde Tsadik  and Desalegn Demise

Petroleum ether extract of root part of Cucumis prophetarum L. afforded one compound 4,4- dimethyl-Stigmast-5-22E,24-trien-3β-ol which has structural similarity with Stigmast-5-22E-dien-24S-3β-ol and Propheterin. More over the 1H-NMR and 13C-NMR spectrum of the isolated compound matched with the literature values of previously reported data’s whereas, the methanol extract afforded one compound 17-octahydro-17-((E)-6-hydroxy-6- methylhept-3-en-2-yl)-9,13-dimethyl-6H-cyclopenta [a] phenanthren-7-yl acetate. The structural elucidation of these compounds was conducted using 1H-NMR, 13C-NMR, UV, IR and DEPT spectroscopic methods.
