Formation of hydroxycinnamoylamides and α-hydroxyacetovanillone in cell cultures of Solanum khasianum

In elicitor-elicited photomixotrophic Solanum khasianum cell cultures, nine phenolic compounds accumulated in the cell culture medium. They were isolated and structurally identified at the cis- and trans-isomers of N-p- coumaroyloctopamine, N-feruloyloctopamine, N-p-coumaroyltyramine and N- feruloyltyramine as well as α-hydroxyacetovanillone. The cis-isomers of the hydroxycinnamoyl moieties were only formed during illumination of the cultures. The hydroxycinnamoylamides showed a transient accumulation with maximum values between 6 and 24 hr after elicitation, depending on the compound. The decrease of the compounds is very likely a peroxidase-mediated reaction.
