Praeruptorin C (Pra-C), one of the principal bioactive components derived from the root of Peucedanum praeruptorum Dunn, has been widely used as an antioxidant and a calcium antagonist to treat diseases, Pra-C partially also protects cortical neurons by inhibiting the expression of GluN2B-containing NMDA receptors and regulating the Bcl-2 family.

Echinatin has significant antioxidant and anti-inflammary activities, it shows strong scavenging activity toward the ABTS + radical, it also inhibits the production of nitric oxide (NO), interleukin-6 (IL-6) and prostaglandin E2 (PGE2) in LPS-induced macrophage cells. Echinatin disturbs the mitochondrial energy transfer reactions and membrane permeability, at a low concentration cause deterioration of respiratory control and oxidative phosphorylation of isolated rat liver mitochondria, inhibits DNP-ATPase activity while stimulating range latent ATPase activity.

Benzoylmesaconine (BEN, an aconitine derivative extracted from heated-Aconiti tuber) induces the generation of CD4+ T cells antagonistic to type 2 T cells (BEN-CD4+ T cells), the combination therapy of IL-12 (an inducer of type 1 T cell responses) and BEN (an inhibitor of type 2 T cell responses) may protect TI-mice from severe HSV-1 infection.

Asperulosidic acid has been recently used in chinese medicine as a useful drug against some tumors. It has anticlastogenic activity, since the anticlastogenic irridoids have an alpha-unsaturated carbonyl group, this structure is considered to play an important role in the anticlastogenicity. Asperulosidic acid can inhibit the seed germination and growth of seedlings of large crabgrass. Asperulosidic acid, and 6-O-(beta-D-glucopyranosyl)-1-O-octanoyl-beta-D-glucopyranose are effective in suppressing 12-O-tedtradecanoylphorbol-13-acetate (TPA)- or epidermal growth factor (EGF)-induced cell transformation and associated AP-1 activity.

Wogonin is one major constituent of Scutellaria baicalensis, possesses potent anticancer activities , the activities are largely due to their abilities to scavenge oxidative radicals, to attenuate NF-kappaB activity, to inhibit several genes important for regulation of the cell cycle, to suppress COX-2 gene expression and to prevent viral infections.

Farrerol has antioxidative, anti-bacterial, anti-inflammatory, antiangiogenic activities, it is a potential candidate for the intervention of endothelial-injury-associated cardiovascular diseases. Farrerol inactivates KEAP-1 or activates the Akt, p38 and ERK to facilitate the release of Nrf2 from Keap1 and subsequent reduces the intracellular production of reactive oxygen species via the induction of HO-1 expression. Farrerol can inhibit angiogenesis through down regulation of Akt/mTOR, Erk and Jak2/Stat3 signal pathway, and can inhibit IL-1β-induced inflammatory responses in osteoarthritis chondrocytes by blocking PI3K/Akt/NF-κB signaling pathway.
