Fig. 1: Stereo-diversity of steroidal glycoalkaloids in the genus Solanum.
From: Enzymatic twists evolved stereo-divergent alkaloids in the Solanaceae family
a Phylogenetic tree of genus Solanum with chirality of C25 stereocenter marked in purple, red, and purple-red stripes denoting species accumulating 25R, 25S, or both stereoisomers. b Chemical structures of aglycones most frequently found in the genus Solanum—configurations at C25 are marked either with purple (25R) or red (25S) dots. c Total Ion Chromatograms (TICs) of tomato leaf and eggplant seed extracts. Most abundant SGAs and saponins are annotated. d Extracted Ion Chromatograms (EICs) for α-tomatine (EIC 1034.5530), dehydrotomatine (EIC 1032.5537), solamargine (EIC 868.5053), and solasonine (EIC 884.5002). Metabolites with different chirality at C25 are appropriately annotated either 25R or 25S. Images of tomato, potato, and eggplant are from BioRender.
