As consumer trends shift towards more natural and ecological consumption patterns, industrialists are actively working towards substituting synthetic chemicals with natural and vegan products that contain bioactive properties. By focusing on the Marrubium vulgare L. species, this study aims to contribute to the valorization of aromatic and medicinal Moroccan plants by characterizing its chemical composition and biological activities, such as antioxidant and antifungal properties.
As consumer trends shift towards more natural and ecological consumption patterns, industrialists are actively working towards substituting synthetic chemicals with natural and vegan products that contain bioactive properties. Thus, considering the shifts in customer demand and the growing concern around vegetable sourced productions, this work aims to contribute to the valorization of aromatic and medicinal Moroccan plants. By focusing on the Marrubium vulgare L. species, our objective is to carry out a physicochemical characterization to determine its chemical composition and biological activities. The volatile fraction collected by hydrodistillation (0.61%) and analyzed by GC-MS (gas chromatography coupled to mass spectrometry) contains five main compounds: 3-Thujanone, Eugenol, Topanol, Menthone and Piperitone. The antioxidant activity has been estimated by applying the DPPH (1,1-diphenyl-2-picrylhydrazyl) free radical scavenging test and the ferric reducing antioxidant power (FRAP). The values of inhibitory concentration prove that our oil is a good antioxidant, with values of IC50 = 1.136 mg/mL and IC50 = 2.998 mg/mL, respectively, for the DPPH and FRAP tests. The results of the antifungal activity indicate a significant inhibition of mycelial growth for both tested molds, as well as a total inhibition of spore production at a concentration of 0.25 mu L/mL.
