Abstract
Sugar beet (Beta vulgaris L. subsp. vulgaris var. altissima) and beetroot (Beta vulgaris L. subsp. vulgaris var. vulgaris) belong to Chenopodiaceae goosefoot family which includes about 1400 species divided into 105 genera. The species Beta vulgaris L. belongs to the family Amaranthaceae (Chenopodiaceae). The Inter simple sequence repeat- PCR (ISSR-PCR) analysis revealed that the sugar beet and beetroot exhibited low level of polymorphism. The preliminary phytochemical screening of the non-flowering aerial parts of sugar beet and beetroot revealed the presence of carbohydrates and/or glycosides, sterols and/or triterpenes, alkaloids and/or nitrogenous bases, tannins, flavonoids and saponins. Also revealed the absence of essential oil, anthraquinone glycosides and cardiac glycosides in both plants under investigation. GLC analysis of the unsaponifiable matter of non-flowering aerial parts of sugar beet revealed the presence of 18 identified components. Hydrocarbons constitute 49.2% while, sterols constitute 27.43% of the unsaponifiable matter. GLC analysis of the fatty acids methyl esters of the non-flowering aerial parts of sugar beet revealed the presence of 13 identified component. The percent of the saturated and the unsaturated fatty acids is 17.58% and 65.57%, respectively. GLC analysis of the unsaponifiable matter of non-flowering aerial parts of beetroot, revealed the presence of 17 identified components. Hydrocarbons constitute 64.8% while sterols constitute 8.5% of the unsaponifiable matter. GLC analysis of the fatty acids methyl esters of the non-flowering aerial parts of beetroot revealed the presence of 11 components
