Apiin is a natural flavonoid, a diglycoside of the flavone apigenin found in the winter-hardy plants parsley^[1] and celery,^[2] and in banana leaf.^[3] 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.^[4] The sugar apiose possibly play a role in winter hardiness of celery, duckweed and parsley.^[5]
