アピイン

Also known as 7-((2-O-beta-D-Apiofuranosyl-beta-D-glucopyranosyl)oxy)-5-hydroxy-2-(4-hydroxyphenyl)-4H-1-benzopyranone, apigenin 7-O-[beta-D-apiosyl-(1->2)-beta-D-glucoside], 5,7,4'-trihydroxyflavone 7-O-[beta-D-apiosyl-(1->2)-beta-D-glucoside], 7-O-(beta-D-Apiofuranosyl-1,2-beta-D-glucosyl)-5,7,4'-trihydroxyflavone

Apiin is a natural flavonoid, a diglycoside of the flavone apigenin found in the winter-hardy plants parsley and celery, and in banana leaf. The glycoside moiety at carbon-7 of apigenin, O-β-D-apiofuranosyl(→)2-β-D-glucosyl, is carried by several other flavones in parsley plant and seed. The sugar apiose possibly play a role in winter hardiness of celery, duckweed and parsley.
