Abstract:
In this current study, we are interested in the study of a part of the prickly pear (the cladodes) which constitute a by-product and can be exploited in many applications and are characterized by their effect on health and their richness in bioactive compounds. Before formulating a cream based on prickly pear cladodes powder, their extract was analyzed. Cladode extracts were studied to optimize the extraction parameters of antioxidants (phenolic compounds) using the central composite plane. The optimal experimental conditions allowing maximization of the extraction of the polyphenols from the cladodes are an ethanol concentration of 40% (v /v) for a time of 90 min with a ratio of 1 g/20 mL. A quantification of total phenolics (TPP) and flavonoids (TF) and an evaluation of the antioxidant activity (anti-radical and reducing power) of the extracts were carried out. Cladodes extract gave a phenolic content of 253.4 mg EAG/g DM and flavonoids content of 14.42 mg Quercetin Equivalent/g Dry Matter. . The potato peel extract has better molybdate (10.65 µg / mL) and DPPH• radical reducing activity (179.75 µg / mL). It also results that the extract of cladodes studied reveals an interesting antioxidant activity for the various tests carried out (anti-radical power with DPPH and reducing power with phosphomolybdate). The IC50s found are 530.18 µg/mL and 43.09 µg/mL in the DPPH and phosphomolybdate tests, respectively. Cladode powder was also used to develop a hand moisturizer cream and the results of sensitivity analyses of the samples of the cream showed that 75% of the judges preferred the control sample, followed by the cream prepared with 0.5% of cladodes powder (63%).
Audience Take Away Notes:
- Through this presentation, the audience will have information on the cactus in general and on its cladodes in particular.
- We will present an innovative method which is used to maximize the extraction of an important class of their bioactive compounds which are the phenolic compounds.
- We have also shown that the extract obtained has an interesting antioxidant power.
- Finally, we will explain how the powder of these cladodes is applied to formulate a moisturizing hand cream.
