Background:

Safflower red is a polyketide synthase-derived quinochalcone glucoside red pigment originally isolated fromC. tinctoriusthat has diverse biological activities.^1,2,3,4Safflower red (100 and 200 µM) inhibits LPS-induced decreases in collagen II and aggrecan levels and reverses LPS-induced increases inTNFexpression in isolated rat nucleus pulposus cells.³It reverses decreases in serum glutathione (GSH) and superoxide dismutase (SOD) levels and increases in serum malondialdehyde (MDA) levels, as well as decreases infarct area and brain edema induced by middle cerebral artery occlusion (MCAO), in a rat model of cerebral ischemia-reperfusion injury when administered at a dose of 40 mg/kg.⁴Formulations containing safflower red have been used in the food, cosmetics, and clothing industries.
