Icyayi cya polifenole ni ijambo rusange kubintu bya polifenolike mumababi yicyayi, akaba ari ifu ya amorphous yera ishobora gushonga byoroshye mumazi, igashonga muri Ethanol, methanol, acetone, na Ethyl acetate, kandi ntigishobora gukomera muri chloroform. Ibiri mu cyayi polifenol mu cyayi kibisi ni byinshi, bingana na 15% kugeza 30% byubwinshi bwabyo. Ibice byingenzi bigize icyayi polifenole ni flavonoide, anthocyanine, flavonol, anthocyanine, acide fenolike, na acide fenolike. Muri byo, flavanone (cyane cyane catechine) nizo zingenzi cyane, zingana na 60% kugeza 80% byicyayi cya polifenol yose yicyayi, ikurikirwa na flavonoide, nibindi bintu bya fenolike bifite ibintu bike ugereranije.
