Solanum species

Among the well-known Solanum species that have been chemically examined are S. nigrum, S. tuberosum (potato) and S. lycopersicum (tomato). From these and other species an alkaloidal glucoside, which was first prepared by Desfosses, has been obtained. This substance has been named solan ine, but it is not certain that all the plants recorded as containing solanine contain the same solanine or that the alkaloid has been obtained in a pure state in each case.

Jansky, 2000). About 64% of wild Solanum species are diploid (2x=24), with most of the remaining species tetraploid (4x=48) or hexaploid (6x=72) (Hijmans et al., 2007).

Fig. 2 TLC-immunostainings of steroidal alkaloid glycosides in the crude extracts of Solanum species fruits. Crude extracts were developed by a CHCl3-Me0H-NH40H solvent system on silica gel TLC plate. After being transferred to a PVDF membrane, the membrane was treated with NaI04 and stained by MAb. Spots 1-3 were identified with khasianine, solamargine, and solasonine, respectively.
