An overview and update on the chemical composition and potential health benefits of <i>Opuntia ficus‐indica</i> (L.) Miller

Abstract

Opuntia ficus-indica (OFI), widely recognized as prickly pear, is native to Mexico and it is distributed in many areas of the world because of its socioeconomic, agronomic, and ecological benefits, besides its large amounts of functional, nutraceutical, and biological activities. Various parts of this plant including the fruit pulp and peel, cladode, and seeds are scientifically proven to have therapeutic potentials and are safe for human use. The contents of phytochemical compounds in each part of the OFI are different. Each pharmacological activity depends on the phytochemical compounds, the components used, and the extraction type. In this review, we summarize the active constituents from different parts of OFI and their pharmacological effects including the antioxidant, wound healing, skin protective, hepatoprotective, anticancer, antidiabetic, antihypercholesterolemic, and anti-obesity activities. Besides its effects on the bone health, cardiovascular system, kidneys, and gastrointestinal tract, its gastroprotective, anti-ulcer, anti-inflammatory, antiviral, neuroprotective, sedative, analgesic, anxiolytic and antimicrobial effects and effects on cognitive and memory function are also mentioned. PRACTICAL APPLICATIONS: Over the past few decades, the health benefits of Opuntia ficus-indica (OFI) have received much attention. All parts of the plant, including the fruit pulp and peel, cladode, and seeds have found use in the treatment of many diseases. The chemical composition of OFI provides both a high nutritional value and various health benefits. Therefore, the aim of this review is to present the up-to-date research carried out on OFI phytochemicals, showing the most important biological activities reported.
