To our knowledge, however,
there have been no reports on the biotransformation
of capsaicinoids to give disaccharides by cultured plant
cells. We report here the biotransformations of capsaicin
(1) and 8-nordihydrocapsaicin, both of which are naturally
occurring capsaicinoids, into the corresponding monoglucosides
and disaccharides, b-primeverosides and b-vicianosides,
which are more soluble in water, by cultured cells of
Catharanthus roseus.
