Benefits of Total Phenolic and Flavonoid Content of Portulaca oleracea as Antioxidant and Antidiabetic: A Review

Abstract

Degenerative disease is a disease that causes damage or destruction to tissues or organs of the body. This damaging process can be caused by age, unhealthy lifestyle, and environmental pollution, which causes a decrease in the production of antioxidant compounds. One of the plants that have the potential as a source of natural antioxidants is Portulaca oleracea. This study aims to determine the phenolic and flavonoid content of P. oleracea and their pharmacological activities. This study uses several databases indexed by Scopus, Pubmed, and Google Scholar. Several studies related to pharmacological activities such as antioxidants and antidiabetics have been reported in this review, where the compounds that play a role in the pharmacological activity of P. oleracea are phenolic and flavonoid compounds. The compound of phenolic and flavonoid compounds and antioxidant activity are influenced by several factors such as growth stages, the solvent used, extraction temperature, and the target metabolite. The antioxidant activity of this plant has been investigated using the DPPH, FRAP, and ABTS assays. As antidiabetic, kaempferol and quercetin are compounds that have the highest activity in this plant.
