Phytochemical composition and <i>in vitro</i> anti‐tumour activities of selected tomato varieties

Abstract

Tomato fruits constitute a healthy source of phytochemicals, although differences exist among varieties. In vitro, all of them inhibit colorectal cancer cell proliferation with Racimo variety at the top, and exercising a selective action on cancer cells by considering the lack of effects on CCD-18 cells. Furthermore, synergy was observed between olive oil and tomato carotenoids in inhibiting HT-29 cancer cell proliferation; conversely, phenolics showed no significant effects and hindered carotenoids actions. © 2016 Society of Chemical Industry.
