Samara Polytech researchers have been investigating the potential anticarcinogenic effects of extracts obtained from plant materials of lingonberry, raspberry, black chokeberry, grapes and other products. They also evaluated their effect on the growth and viability of colon cancer cells. The research was carried out within the framework of the state assignment for fundamental research. Its results were published late last year, in the journal Proceedings of Universities. Applied Chemistry and Biotechnology.
One of the authors of this study, associate professor of the Department of Technology and Organization of Public Catering of Samara Polytech Natalya Eremeeva explains: "Polyphenols are the largest variety of plant components. It is this class of chemical compounds that have shown powerful antioxidant properties. They actively fight against cellular damage caused by free radicals, slowing down the aging and preventing oxidation. In addition, they protect the body from inflammatory, cardiovascular, neurodegenerative diseases, and some forms of cancer. We studied in detail the beneficial properties of lingonberry, raspberry, black chokeberry, grapes, Krasnodar green tea, ginseng, fireweed and coffee.”
When conducting the MTT cytotoxicity test, the scientists found that the ginseng extract was the most cytotoxic, and the coffee extract was the least cytotoxic. It has been proven that all the studied extracts are able to reduce the expression of pro-inflammatory genes. The most pronounced inhibitory effect on the expression of these genes is possessed by the extracts of chokeberry and fireweed.
