Effects of Crocus sativus extract and crocin on proliferation of three human colorectal cancer cells. Cancer cells were exposed to Crocus sativus extract or CSE (a) and crocin (b) for 48 h and cell proliferation was determined by MTS method. CSE and crocin have the most potent anti-proliferative activities on HCT-116 cells. Control at 48 h is normalized to 100%
