Riccardin C is a macrocyclic bis(bibenzyl). It is a secondary metabolite isolated from the Siberian cowslip subspecies Primula veris subsp. macrocalyx,^[1]^[2] in Reboulia hemisphaerica^[3] and in the Chinese liverwort Plagiochasma intermedium.^[4]

In 2005, the compound was prepared by total synthesis together with the strained compound cavicularin.^[5]^[6]
