Since the discovery of (2α,3β)-2,3-dihydroxyolean-12-en-28-oic acid, also known as
maslinic acid, many studies have examined its biological activity, which has been shown to promote
health and resist various diseases. This article focuses on previous research on maslinic acid
and mainly reviews its reported effects on cardiovascular diseases, neuroprotection, diabetes, cancer,
inflammation, and pathogens. Maslinic acid exerts positive effects on both cell and animal
models of disease. Although its mechanism of action has not yet been completely elucidated, maslinic
acid is feasible as a nutritional additive and has the potential to be developed as a drug.
