Cercis chinensis Bunge

Okanin, effective constituent of the flower tea Coreopsis tinctoria, attenuates LPS-induced microglial activation through inhibition of the TLR4/NF-κB signaling pathways.

Flavanomarein is a substance with cytoprotective, anti-inflammatory and antioxidant activities, with a K_a of 3.064e-5 M against human Syk. Flavanomarein enhances the phosphorylation level of AKT, regulates the expression of PKC-δ, P85α, PKC-β1, Sirt1, Bcl-2 and ICAD, and inhibits the nuclear translocation of NF-κB p65. Flavanomarein regulates EMT marker proteins, promotes the proliferation of HK-2 cells, and protects neuronal cells from 6-OHDA-induced neurotoxic damage. Flavanomarein can be used in studies related to Parkinson's disease and diabetic nephropathy.

Taxifolin 7-O-β-D-glucoside (Taxifolin 7-O-glucoside) is a flavonol and active antioxidant that can be isolated from Scutellaria baicalensis. Taxifolin 7-O-β-D-glucoside participates in pathogen defense and ultraviolet damage protection in the seed coat during seed germination of Scutellaria baicalensis.

Maritimein is an aurone that can be isolated from Coreopsis tinctoria. Maritimein shows strong diphenyl(2,4,6-trinitrophenyl)iminoazanium (DPPH) radical-scavenging activity with an IC₅₀ value of 4.12 μM. Maritimein can be used for the research of cardiovascular disease.

Coreopsin is a natural product that can be isolated from Coreopsis tinctoria Nutt. flower. Coreopsin can be used for hypertension and diabetes research.

Coretinphencone is a phenolic compound that can be isolated from the buds of Coreopsis tinctoria Nutt.

(2R)-Flavanomarein is a predominant flavonoid of Coreopsis tinctoria Nutt with protective effects against diabetic nephropathy. (2R)-Flavanomarein has good antioxidative, antidiabetic, antihypertensive and anti-hyperlipidemic activities.

Sikokianin E is a biflavonone compound that can be isolated from Coreopsis tinctoria.

Emodic acid (NSC624610) is an anthraquinone compound isolated from A. microcarpus, which can inhibit the proliferation of cancer cells by inhibiting the activity of NF-κB. Emodic acid can also inhibit the phosphorylation of p38, ERK and JNK, the secretion of tumor-promoting cytokines IL-1β and IL-6, and the expression of VEGF and MMP, thereby inhibiting the invasion and migration potential of cancer cells.

Coreoside B (14-Hydroxycoreoside A) can be isolated from Coreopsis tinctoria Nutt. and has weak antibacterial activity.

Isocoreopsin (Flavanocorepsin) is an anticancer agent that can be isolated from Butea monosperma flowers.
