Ligustilide and senkyunolide A, two of the most abundant Ligusticum chuanxiong constituents, have vasorelaxation activities in contractions to various contractile agents in rat isolated aorta.

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.
