Sesquiterpene Glycosides from Calendula persica.
The polar fractions of the extract of the aerial parts of CALENDULA PERSICA afforded eight sesquiterpene glycosides, five derived from viridiflorol, two of beta-eudesmol, and one of 4alpha-hydroxygermacra-1(10) E,5E-diene. In addition to fucopyranosides, also chinovopyranosides were present. The structures were elucidated by high field NMR techniques.
