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.

1. Apiin has potential to reduce the risk of cancer since it has anti-tumor activity. It can induce the apoptosis of human gastric cancer cells via activating mitochondrial signal transdution pathway and promotes proliferative inhibition and apoptotic induction of human acute myeloid leukaemia HL-60 cells by cisplatin (DDP)

2.Apiin also could potentially be useful in allergic conditions since it can have anti-inflammatory properties.

3.Apiin,is a non-toxic plant flavonoid,having been shown to free radical scavenging properties and antioxidant effects.

4.Apiin is antiviral agent for the treatment of HIV and other infections.
