Glycosides calendula

The satire approach was used for the structural determination of five oleanolic acid glycosides from Calendula arvensis 32-36 (23) and 3p, 2ip, 23 trihydroxy-olean-12-en-28-oic acid bisglycoside 44... [Pg.126]

An inhibitory effect against VSV multiplication was observed for five oleanolic acid glycosides from Calendula arvensis while rhinovirus (HRV) replication was significantly affected by only one compound, a bidesmosidic triglycoside of oleanolic acid [157],... [Pg.665]

Calendulae flos (2) is characterized by pairs of yellow-orange isorhamnetin and qucrcc-tm glycosides. The major zones are due to rutin (R, 0.4) and narcissin (R, 0.45), isorhamnetin- and quercetin-3-O-glucoside (R, 0.6-0.7) and isorhaninetin-rutinosyl-ghicoside at R, 0.2. [Pg.214]

It is instructive to concentrate on the flavonoids, as these are of primary importance in qualitative assays of several HDs. Silica gel as stationary phase and ethyl acetate-ethyl methyl ketone-formic acid-water (50 30 10 10 by volume) as mobile phase is used in the analysis of flavonoids with C-glycosides (hawthorn, passion flower), and a mobile phase of ethyl acetate-formic acid-acetic acid-water (100 11 11 27 by volume) is used as the basic solvent for 0-glycosides (arnica, calendula, chamomille). Following spraying of the plates with 2-aminoethyldiphenyl-borinate (NTS, 1% in methanol) and subsequent treatment with poly(ethylene glycol) 4000 (PEG, 5% in ethanol), flavonoids display yellow to green fluorescence under UV irradiation at 365 nm. The frequently observed blue spots represent phenol... [Pg.3660]
