Maslinic acid is a compound derived from dry olive-pomace oil (an olive skin wax) which is a byproduct of olive oil extraction. It is a member of the group of triterpenes known as oleananes.

Pharmacology[edit]

In vitro study shows that maslinic acid inhibits serine proteases, key enzymes necessary for the spread of HIV within an individual's body.[1] It also has in vitro antiproliferative effects on colon cancer cells.[2] Maslinic acid increases EAAT2 (GLT-1) glutamate reuptake and may reduce glutamatergic toxicity in rats.[3] Additionally, maslinic acid serves as a glycogen phosphorylase inhibitor in mouse liver,[4][5] as evidenced by increased glycogen accumulation in rainbow trout liver.[6]

Clinical significance[edit]

Maslinic acid demonstrates antioxidant capabilities against oxygen and nitrogen reactive species.[7][8] It also exhibits a suppressive impact on proinflammatory cytokines like TNF-α and IL-6 in murine macrophages.[8] These mechanisms could contribute to enhanced protein synthesis, growth rates, and joint support.[9] Maslinic acid has been shown to improve muscle mass in the elderly when combined with resistance exercise.[10]
