7-O-methylpelargonidin glycosides from the pale red flowers of Catharanthus roseus.
Two new anthocyanidin glycosides were isolated from the pale red flowers of Catharanthus roseus 'Equator Apricot with Red Eye', and identified as 7-O-methylpelargonidin 3-O-[6-O-(alpha-rhamnopyranosyl)-beta-galactopyranoside] and 7-O-methylpelargonidin 3-O-(beta-galactopyranoside) by chemical and spectroscopic methods.
