Antitumor activity

Picrocrocin as component of saffron displays same antitumor activity that have great potential for the prevention and treatment of various cancers through affecting cellular DNA and RNA synthesis and free radical scavenging activities of cancer. The experiments results for studying the effect of picrocrocin on proliferation of human tumoral cells (HeLa cell) in vitro showed that picrocrocin have a dose dependent inhibition of cell growth, and doses of picrocrocin inducing 50% inhibition of HeLa cell growth are 3 mM, in which picrocrocin have minor cytotoxicity for normal cells. Thus, picrocrocin can inhibit the growth of cancer cell. Other study results have showed that picrocrocin with highly bioaccessible could be transported quickly and reduced the proliferation of human adenocarcinoma and hepatocarcinoma cells.
