Calendula officinalis (L.), Extract

Please note, this OEL/ADE monograph also applies to Calendula officinalis (L.), oil (CAS RN 70892-20-5). Calendula officinalis, also known as marigold, is a species belonging to the family Asteraceae, formerly Compositae. Many secondary metabolites are responsible for the biological activity of C. officinalis. The main group are flavonoid compounds, among others including aglycones (quercetin, isoquercetin, rutinoside, narcissin), and glycosides (quercetin-3- rutinoside, isorhamnetin-3-neohesperidoside (calendoflavoside), and quercetin 3- neohesperidoside (calendoflavobioside)). Terpenoids are an important group of secondary metabolites which occur in the C. officinalis inflorescence and are responsible for its biological activity. Marigold flowers were shown to contain polysaccharides (including neohesperidoside and its derivatives, arabinogalactan, ramnoarabinogalactan) with immunostimulatory properties and sesquiterpenoid lactone, calendin.
