ABSTRACT: This work is a taxonomic study on flavonoids in the
roots of selected species belonged to family
Solanaceae. These species considered as: Lycopersicum esculentum, Solanum melongena and Solanum tuberosum. These species distributed in different localities in
Sudan. The selected members have nutritive, medicinal and economic importance,
extra of that, the present study included botanical and chemical studies. The
collected species have been updated due to nomenclature and synonymy. The geographical
distribution of the selected members has been indicated. The chemical studies
included identification of the flavonoid
compounds using Gas Chromatography Mass Spectrophotometer (GC-MS). Eighty-three flavonoid compounds were detected
in the roots of family Solanaceae. The highest number (32) was detected in the roots of Solanum tuberosum.
A single flavonoid compound was restricted only to the roots of Solanum melongena. This was:
(cyclohexanol-5-methyl-2-(1methylene), {1R-1.alpha, 2beta, 5.alpha}). Four
taxonomic markers were identified for the roots of Lycopersicum esculentum. Ten
taxonomic markers were identified in the roots of Solanum tuberosum.
