Ononin, an isoflavonoid, was isolated from the soils of cultivated areas associated with the perennial weed,Pluchea lanceolata, aqueous solutions of this compound can significantly inhibit root and shoot growth of mustard at 1×10(-4) M, 5×10(-4) M, and 1×10(-3)M.

Isorhamnetin, a natural flavonol aglycon, is a tyrosinase inhibitor and has anti-adipogenic, cardioprotective, anti-tumor, and antioxidant activities. it inhibits the H(2)O(2)-induced activation of the intrinsic apoptotic pathway via ROS scavenging and ERK inactivation, it inhibits NF-κB signaling. Isorhamnetin prevents angiotensin II (AngII)-induced endothelial dysfunction by inhibiting the overexpression of p47(phox) and the subsequent increases O2-production, resulting in increased nitric oxide bioavailability.

Scutellarein has antioxidant, antitumor, anti-adipogenic, antiviral and anti-inflammatory activities, it can improve neuronal injury, has better protective effect in rat cerebral ischemia. Scutellarein may serve as a SARS-CoV chemical inhibitor, it also exerts strong inhibition towards the tested UDP-glucuronosyltransferase isoforms.

Baicalin, saikosaponins, and baicalein have antitumor effects on human hepatoma cell lines and bladder cancer cell lines.[1,2]

Apigenin 7-O-β-D-glucuronide(AG), an active flavonoid derivative isolated from the agricultural residue of Juglans sigillata fruit husks, possesses multiple pharmacological activities, including anti-oxidant, anti-complement, and aldose reductase inhibitory activities; AG protects mice from LPS-induced endotoxin shock by inhibiting proinflammatory cytokine production, suggests that AG may be used as a source of anti-inflammatory agents as well as a dietary complement for health promotion.

Arctigenin, naturally occurring in Bardanae fructus, Saussurea medusa, Arctium lappa L., Torreya nucifera and Ipomea cairica, is a phenylpropanoid dibenzylbutyrolactone lignan with antioxidant and anti-inflammatory activities, it can potently inhibit the activity of MKK1 in vitro with the IC(50) value of 1 nM, and inhibit activation of MAP kinases including ERK1/2, p38 kinase and JNK through the inhibition of MKK activities, leading to AP-1 inactivation, which might, at least in part, contribute to the inhibition of TNF-α production, inhibits expression via suppressing JAK-pathway in macrophages.[1,2]

Forsythoside I is a natural product from forsythia suspense (thunb.) vahl.
