Abstract
The purple and black tomato are sources of different antioxidants such as carotenoids and flavonoids that seem to have dose-dependent antioxidant, anti-inflammatory, anti-proliferative and hypnotic effects. The aim of this review is to discuss their advantageous role in health promotion and prophylaxis against chronic conditions induced by inflammation and oxidative stress. Data research was conducted on five major databases using specific keywords to extract relevant articles. The anti-proliferative effect was seen in a deep purple tomato in two human cancer cell lines: human colorectal adenocarcinoma cell line and HeLa cell line. Potential anticancer properties were attributed to radical scavenging activity, enzyme detoxification, reduced cell proliferation, angiogenesis and invasiveness. Ingestion of purple and black tomato seeds was proven to increase circulating melatonin levels and improve hypnosis. Purple and black tomato anthocyanin treatment was also significantly associated with increased sperm motility and spermatogenic cell density. The high content of bioactives in purple and black tomato may find application in prevention of cancer and cardiovascular diseases as well as management of sleep and fertility disorders.
