Veronica: Acylated flavone glycosides as chemosystematic markers

Summary: | HPLC/DAD and LC–MS of an extract of
Veronica spicata (subgenus
Pseudolysimachium, Plantaginaceae) revealed the presence of six 6-hydroxyluteolin glycosides acylated with phenolic acids, three of which are new compounds and which we called spicosides. A flavonoid survey of seven more species belonging to
V. subgenus
Pseudolysimachium and eight species of
V. subgenus
Pentasepalae showed that all the
Pseudolysimachium species and four of the
Pentasepalae species produced 6-hydroxyflavone glycosides, whereas the remaining four
Pentasepalae species contained acetylated 8-hydroxyflavone glycosides instead. Spicosides appeared to be common in subgenus
Pseudolysimachium (detected in five out of eight species), but we did not find them in subgenus
Pentasepalae. Previously, acetylated 8-hydroxyflavone glycosides have been isolated from or detected in eight species of
V. subgenus
Pentasepalae (in 13 species altogether including the new results) and seven species of
V. subgenus
Pocilla. However, 6-hydroxyflavone glycosides occur in some other species of these subgenera. The results are discussed in an evolutionary context. |
