Biological activity of food colour Crocus sativus

Sweet Potato Powder has been proved that saffron has anticancer effect. The Spirulina Powder effect of the total extract of saffron ethanol and different components of saffron on the growth of human tumor cells in vitro was studied. The results showed that the half lethal dose of different components to HeLa cells were: Capsicum Oleoresin 2.3mg/ml of saffron dry stigma extract, 3 mmol / L of saffron, 0.8mmol/l of saffron aldehyde and 3 mmol / L of saffron bitter.

Modern research has found that saffron preparation has obvious anti-cancer and anti-cancer ability, and its anti-cancer mechanism may be to destroy the synthetase system, that is, to destroy a protein link medium which is essential for cell synthesis, so as to inhibit the synthesis of and, and achieve the effect of inhibiting the growth of tumor cells.

Ferulic Acid, crocin also inhibited the activity of protein kinase and the expression of proto oncogene. It was found that saffron extract can inhibit the growth of human tumor cells. The results showed that the cells treated with saffron had swelling and plasma membrane rupture, which indicated that the cytotoxicity of the cells might be caused by the absorption of extracellular fluid. Considering water solubility and high inhibition, crocin is considered to be one of the most promising cancer drugs in crocin.

Garcia Olmo et al. Used crocetin and carotenoid glycosides extracted from Crocus drying stigma for a long time to treat rats inoculated with colon cancer. It was found that crocetin and carotenoid glycosides can prolong the life span of female rats and slow down the growth rate of cancer cells, but they have no effect on male rats. Immunoserum analysis showed that the two compounds had only slight toxicity to kidney.
