The present study aims to identify and characterize the chemical compounds present in the extracts of cactus pear Opuntia dillenii (OD) fruit which grow in southern Iraq and offer different health benefits. The physicochemical properties of the fruit juices (pulp and peels) were investigated. Fruit pulp and peel extracts carried the symbols: hexane pulp extract (HPuE), hexane peel extract (HPeE), ethanolic pulp extract (EPuE), and ethanolic peels extract (EPeE). The activel compound screened by gas chromatography-mass spectrometry (GC-MS). HPuE and HPeE contained 40 bioactive compounds and 60 bioactive compounds were detected in EPuE and EPeE. The scavenging activity of DPPH free radicals records a high level of inhibition ranging from 34.8 to 90.3% for EPeE and from 32.9 to 89.9% for EPuE, while hexane extracts scavenging activities (HPeE and HPuE) were 24.9-78.9% and 20.7-73.3% respectively at concentrations of 20 – 80 µg.ml-1 this activity has received considerable attention because of their physiological functions
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
