Description and Uses
Orientin is a flavone glycoside originally isolated from P. orientale that has diverse biological activities, including antioxidant, antibacterial, and anti-inflammatory properties. Orientin scavenges 2,2-diphenyl-1-picryl-hydrazyl (DPPH; ) radicals with an IC50 value of 316.21 μg/ml. 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. 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). 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.
Orientin is a flavone, a chemical flavonoid compound. Orientin have been investigated for its anti-oxidant, antihypertensive and antihyperlipidemic effects.
