Lycopene is the pigment principally responsible for the characteristic deep-red color of ripe tomato fruits and tomato products. Lycopene is an antioxidant scavenger, hypolipaemic agent, inhibitor of pro-inflammatory and pro-thrombotic factors, thus potentially of benefit in cardiovascular disease (CVD). Lycopene may play a role in the prevention of Renal cell carcinoma, it also may play a role against obesity-related complications.

Nomilin has immunomodulatory, antioxidant, anti-human immunodeficiency virus(HIV), cancer chemopreventive, antiangiogenic, anti-obesity and anti-hyperglycemic effects. Nomilin inhibits tumor-specific angiogenesis by downregulating VEGF, NO and proinflammatory cytokine profile and also by inhibiting the activation of MMP-2 and MMP-9. It inhibits osteoclastogenesis in vitro by suppression of NFATc1 and MAPK signaling pathways, indicates that nomilin-containing herbal preparations have potential utility for the prevention of bone metabolic diseases.

Lobetyolin has a protective role in gastric mucosa injury,and the mechanism may be relate to the increase in level of 6-K-PGF1αand the inhibition the excretion of gastric acid and EGF.
