Abstract
Two polymethoxyflavones,5-O-demethylnobiletin and 7,4'-dihydroxy-5,6,8,3'-tetramethoxyflavones were isolated from the chloroform extracts of fresh yellow-orange berries of Solanum abutiloides. The two compounds are reported for the first time in the genus Solantum. The light petroleum fraction, gave branched aliphatic alcohol, α-amyrin, lupeol, phytosterol and stigmasterol glucoside. Identification of these compounds was established on the basis of 1'H-NMR, MS, UV, IR and comparison with authentic samples. GLC analysis of fatty acid methyl esters revealed the presence of 15 fatty acids, where linoleic, palmitic and oleic acids represented 37.54, 32.61 and 17.52%, respectively.
