Orientin is a flavone glycoside originally isolated from P. orientale that has diverse biological activities, including antioxidant, antibacterial, and anti-inflammatory properties.1,2,3,4 Orientin scavenges 2,2-diphenyl-1-picryl-hydrazyl (DPPH; Item No. 14805) radicals with an IC50 value of 316.21 μg/ml.2 It also decreases the cytopathic effects of parainfluenza type 3 virus with an IC50 value of 11.7 μg/ml and a cytotoxic concentration (CC50) value of 375 μg/ml in Hep-2 cells.3 Orientin (5-40 μM) inhibits LPS-induced barrier disruption, decreases the expression of toll-like receptor 4 (TLR4), phosphorylated p38, and NF-κB, and decreases TNF-α production and IL-6 secretion in a dose-dependent manner in human umbilical vein endothelial cells (HUVECs).4 It also prolongs survival in a mouse model of LPS-induced lethal endotoxemia when administered at a dose of 36 μg/animal 12 hours after LPS administration. | [Chemical Properties]

Orientin is a flavone, a chemical flavonoid compound. Orientin have been investigated for its anti-oxidant, antihypertensive and antihyperlipidemic effects. | [Definition]
ChEBI: A C-glycosyl compound that is luteolin substituted by a beta-D-glucopyranosyl moiety at position 8. | [in vivo]
Orientin (0.1–10 mg/kg for p.o.;once) inhibits allergic reaction in PCA mouse model[1].
Orientin (10–40 mg/kg for i.p.;once daily for 12 days) has an anti-neuroinflammatory effect in SNL rat model[2]. | Animal Model: | PCA mouse model[1] | | Dosage: | 0.1–10 mg/kg | | Administration: | Oral gavage (p.o.); Euthanized mouse after 1 h | | Result: | Significantly suppressed PCA reactions in PCA mouse model. |
| Animal Model: | SNL rat model[2] | | Dosage: | 10, 20, 40 mg/kg | | Administration: | Intraperitoneal injection (i.p.); Once daily for 12 days | | Result: | Alleviated the downreg-ulation of PWL and promoted the behavior recovery in SNL rat model.
Decreased the levels of IL-6, IL-1β and TNF-α.
Increased the level of anti-inflammatory IL-10.
Down-regulated the level of MDA.
