Cernuine is found in lemon and citrus. 4,6-Dihydroxy-2-[(3,4-dihydroxyphenyl)methylene]-3(2H)-benzofuranone, 9CI Aureusidin Cernuine C15H10O6 286.2363 286.047738052 (2E)-2-[(3,4-dihydroxyphenyl)methylidene]-4,6-dihydroxy-2,3-dihydro-1-benzofuran-3-one (2E)-2-[(3,4-dihydroxyphenyl)methylidene]-4,6-dihydroxy-1-benzofuran-3-one 480-70-6 OC1=CC(O)=C2C(=O)\C(OC2=C1)=C/C1=CC(O)=C(O)C=C1 InChI=1S/C15H10O6/c16-8-5-11(19)14-12(6-8)21-13(15(14)20)4-7-1-2-9(17)10(18)3-7/h1-6,16-19H/b13-4+ WBEFUVAYFSOUEA-YIXHJXPBSA-N belongs to the class of organic compounds known as aurone flavonoids. These are flavonoids containing a 2-Benzylidene-1-benzofuran-3-one based core. Aurone flavonoids provide the bright yellow color of some important ornamental flowers, such as snapdragon (Antirrhinum majus).
