Chemical Information
FooDB NameMaslinic acid
DescriptionMaslinic 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.; Maslinic acid is a pentacyclic triterpene, found in the non-glyceride fraction of olive pomace oil (Olive pomace oil, also known as "orujo" olive oil, is a blend of refined-pomace oil and virgin olive oil, fit for human consumption). Pentacyclic triterpenes are natural compounds which are widely distributed in plants. These natural products have been demonstrated to possess anti-inflammatory properties. Triterpenoids have been reported to possess antioxidant properties, since they prevent lipid peroxidation and suppress superoxide anion generation. The triterpenes have a history of medicinal use in many Asian countries. Maslinic acid exhibits both pro- and anti-inflammatory properties depending on chemical structure and dose and may be useful in modulating the immune response; further studies are required to confirm the immunomodulatory behaviour of this triterpenoid, and characterise the mechanisms underlying the biphasic nature of some aspects of the inflammatory response.
