ABSTRACT

We studied the richness of phenolic compounds and the antioxidant activities of Opuntia ficus indica L. cladodes by comparing two types of extraction, maceration and soxhlet made with methanol / water (8 : 2, v/v). The results showed that the extraction by maceration is better than that by soxhlet with a total polyphenol concentration of 36.7 mg GAE/ g DW, a total antioxidant activity of 18.5 mg GAE/ g DW and an IC50 of 77.5 μg/ml against DPPH radical scavenging. These results are very vaforable for a sustainable valorisation of the prickly pear cladodes for medicinal, pharmacological and alimentary fields.
