Chemoprevention, which includes the use of synthetic or natural agents (alone or in combination) to block the development of cancer in human beings, is an extremely promising strategy for cancer prevention. Apium graveolens seeds have been assessed for chemopreventive activity. The antiproliferative effect of the methanolic extract of Apium graveolens was evaluated in vitro on two human cell li...

The diol-analog of rutacridone epoxide, gravacridondiol, which was also present i...
