title: Betacyanins from plants and cell cultures of Phytolacca americana.
abstract: Betacyanins from cell cultures of Phytolacca americana were characterized and compared with those of the stems and ripening fruits of the plant. Whereas in fruits prebetanin (betanin 6'-O-sulphate) and its isoform predominate, in the stem and cell cultures feruloylated derivatives occur as the major components. These were rigorously identified by various spectroscopic techniques (DAD-HPLC, NMR, LC-MS and electrospray MS-MS) and carbohydrate analyses as betanidin 5-O-[(5"-O-E-feruloyl)-2'-O-beta-D-apiofuranosyl] -beta-D-glucopyranoside, a new betacyanin of higher plants, and betanidin 5-O-(6'-O-E-feruloyl)-beta-D-glucopyranoside (lampranthin II), together with their isoforms.
