Abstract
Solanum L., the largest genus of family Solanaceae, comprises about 1500 species distributed in the temperate and tropical regions. Although several members of the genus were subjected to extensive investigation; yet, reports on S. villosum Mill. are scarce, a fact that encouraged the authors to perform the current study. The plant under investigation could be identified through its morphological characteristics as Solanum villosum Mill. spp. puniceum (Kirshl.) edmonds by the aid of specialized taxonomists and through comparison with published data. Plant material was obtained from plants successfully cultivated at the Experimental Station for Aromatic, Medicinal and Toxic Plants (Faculty of Pharmacy, Cairo university, Giza, Egypt). Propagation was achieved from seeds of plants wild growing in Saudi Arabia. Aerial parts were collected in the fruiting stage during the years 2012-2014. The plant is an annual herb, subglabrous to villous, up to 60 cm high and is distributed in Egypt; Kenya and North Africa. Genetic profiling, proximate analysis, phytochemical screening of the aerial parts and examination of the extractives as well as metabolite profiling via HPLC-MS. were performed. The n-hexane extractive was fractionated via saponifcation to yield the saponifiable and unsaponifiable matters. GLC-FID analysis revealed the presence of palmitic acid (26.81%), linoleic acid (34.82%) and linolenic acid (25.07%) in the saponifiable fraction, and of cholesterol, stigmasterol and Ý-sitosterol in the unsaponifiable one
