Ammodaucus leucotrichus is a medicinal plant commonly used in Algeria by the indigenous populations, especially
due to its therapeutic effects. In this context, the aim of the present study was to chemically characterize
the essential oil of A. leucotrichus fruits (EOALF) growing in Algerian Sahara, and to evaluate its bioactive
properties (antimicrobial, antioxidant and anti-inflammatory). Considering the interest of the cosmetic industry
for natural ingredients, and taking into account the obtained biological properties, the essential oil was also
evaluated by incorporation in a base cosmetic (cream). The essential oil was extracted with a yield of
2.58 ± 0.17%, being perilla aldehyde identified as the main component, accounting for 85.6% of the total
composition. Concerning the tested bioactivities, EOALF presented antioxidant potential, a strong anti-inflammatory
activity, and was effective against the tested microbial strains (Staphylococcus aureus, Eschericia coli
and Pseudomonas aeruginosa), being S. aureus the most sensitive bacteria. After incorporation in a base cosmetic,
the developed formulation was able to preserve the EOALF bioactivities along 28 days under storage. The obtained
results, with relevance for the strong-anti-inflammatory activity, pointed out the interest to exploit this
essential oil as a cosmeceutical ingredient in the cosmetic industry.
