The essential oils were analyzed using gas chromatography-mass spectrometry (GC-MS-MS) analysis. The outcomes revealed distinct chemical profiles indicative of specific chemotypes within each species. Indeed, <em>M. chamomilla</em> essential oil (MCEO) contained sabinene (16.03 %), camphor (11.22 %), 3,6-dihydrochamazulene (14.22 %), and chamazulene (12.84 %) as its primary constituents. <em>C. ladanifer</em> essential oil (CLEO) prominently featured camphene (31.5 %), α-pinene (15.76%), and bornyl acetate (15.73 %), while <em>P. lentiscus</em> essential oil (PLEO) was rich in D-limonene (21 %), β-myrcene (14.89 %), α-pinene (13.93 %), and terpinen-4-ol (9.75 %).

The predominant constituents were pulegone (17.56%), mintlactone (10.62%), _D-carvone (9.24%), eucalyptol (7.53%), and thymol (6.06%). The antidiabetic effects were assessed by measuring the inhibition of two digestive enzymes (α-glucosidase and α-amylase). The dermatoprotective effect was evaluated based on the inhibition of elastase and tyrosinase, and neuroprotective activity was studied by examining the inhibition of acetylcholinesterase (AChE) and butyrylcholinesterase (BChE). Additionally, molecular docking analysis was used to determine the interactions between the main MPEO compounds and the enzymes targeted. Antioxidant activity was estimated using <em>in vitro</em> FRAP, DPPH, and ABTS assays. Furthermore, the antibacterial potential was evaluated against pathogenic strains using the micro-broth dilution method. Our results indicate significant antioxidant and neuroprotective activities of MPEO, along with promising antidiabetic and dermatoprotective potential, surpassing references. Additionally, all bacterial strains tested were susceptible to MPEO, with MIC values lower than those of MBC for all bacteria except <em>L. monocytogenes</em>. These <em>in vitro</em> findings were supported by <em>in silico</em> analysis, showing that menthelactone and pulegone presented strong binding affinities with key enzymes involved in glucose regulation and pigmentation.
