A derivative of vitamin E
Garcinoic acid is a derivative of vitamin E originally isolated from C. grandiflora.1 It inhibits IL-1β-induced microsomal prostaglandin E2 synthase-1 (mPGES-1) activity in A549 cells when used at concentrations of 1 and 10 μM.2 It has higher antioxidant activity relative to (±)-α-tocopherol in a cell-free assay when used at a concentration of 0.15 mM.3
