The phenolic compounds of avocado seed mainly in the form of catechin, hydroxybenzoic acid, caffeic acid, chlorogenic acid, coumaric acid, ferulic acid and triterpenoid glycosides. Different variety of avocado, extraction methods, maturity and growth may offer variation in phenolic content. Functional properties of avocado seed with the presence of phenolic compounds are vasorelaxant activity, analgesic, antiviral, antioxidant, wound healing, and anticancer. Triterpenoid in avocado seeds have been investigated as anticancer effects toward breast MCF7 cancer cells and showed the value of IC50 is 62 ug/mL as cytotoxic activity. Spectrophotometry usually used to determine the phytochemicals in avocado seed such as saponins, tannins and flavonoids.
