With lower ketones (acetone, methyl ethyl ketone) in weakly acidic solution, flavonoid rhamnosides and rutinosides form alkylidene derivatives at the cis-diol grouping of the rhamnose residue.It has been found that the formation of alkylidene derivatives of flavonoid glycosides is a side reaction that takes place during the chromatographic process on an "acid" polyamide sorbent.
