- Abstract : Today, the emerging potential of l’Opuntia ficus indica (L.) (Prickly pear) oil application in pharmaceutical and cosmetic industries has prompted researchers to study its stability and to determine its compounds in order to improve its economic utility. In this context, the utmost aim of the current research was to assess the physicochemical properties of Opuntia ficus india L extracted oil from Tunisia and to appraise its antimicrobial activity and its cytotoxic activity against HeLa cell lines.
The prickly pear oil was analysed for antimicrobial activity by disc diffusion assay and minimum inhibition concentration against four bacteria. The oil was also tested for the DPPH free-radical scavenging activity and cytotoxicity.
Prickly pear oil extracted by cold press was light yellow in colour, stable and had good quality with low peroxide value.
Linoleic acid (55.731 %), oleic acid (20.788 %) and β-sitosterol were the most prominent in prickly pear extracted seed oil. The oil showed moderate antibacterial activity when compared to the reference (gentamicin). The oil recorded highest anti-bacteria activities against Bacillus subtilis. It exhibited remarkable antioxidant property due its richness of α-tocopherol.
According to the MTT test, prickly pear oil seems to be free of any toxicity and could be used in dermopharmacy. - Pagination : 9-30
