“…Because the fatty acids, fatty oils, and surfactants used in the formulation of cosmetic products frequently emit an unpleasant odor, their main use in the cosmetic industry is due to their pleasant aromas [ 10 ]. Morocco offers a rich and diverse floristic biodiversity as a result of its varied climatic and ecological conditions [ 11 ]. The gradual discovery of the uses for their essential oils (EOs) in healthcare and other areas of economic interest, as well as for their anti-inflammatory, antiseptic, antiviral, antimicrobial, and antitoxic properties, has been particularly advantageous for aromatic and medicinal plants [ 9 ].…”

In this work, the chemical composition and antioxidant and antimicrobial activities of the essential oils (EOs) of six species—Laurus nobilis, Chamaemelum nobile, Citrus aurantium, Pistacia lentiscus, Cedrus atlantica, and Rosa damascena—have been studied. Phytochemical screening of these plants revealed the presence of primary metabolites, namely, lipids, proteins, reducing sugars, and polysaccharides, and also secondary metabolites such as tannins, flavonoids, and mucilages. The essential oils were extracted by hydrodistillation in a Clevenger-type apparatus. The yields are between 0.06 and 4.78% (mL/100 g). The analysis of the chemical composition carried out by GC-MS showed the presence of 30 to 35 compounds and represent between 99.97% and 100% of the total composition of EOs, with a variation in the chemical composition detected at the level of the majority compounds between these species. Indeed, in the EO of Laurus nobilis, 1,8-cineole (36.58%) is the major component. In Chamaemelum nobile EO, the most abundant compound is angelylangelate (41.79%). The EO of Citrus aurantium is rich in linalool (29.01%). The EO of Pistacia lentiscus is dominated by 3-methylpentylangelate (27.83%). The main compound of Cedrus atlantica is β-himachalene (40.19%), while the EO of Rosa damascenaa flowers is rich in n-nonadecane (44.89%). The analysis of the similarity between the EOs of the plants studied by ACH and ACP showed that the chemical composition of the EOs makes it possible to separate these plants into three groups: the first represented by Chamaemelum nobile, because it is rich in oxygenated monoterpenes, the second defined Cedrus atlantica and Rosa damascena, which are rich in sesquiterpenes, and the third gathers Pistacia lentiscus, Laurus nobilis and Citrus aurantium, which are composed of oxygenated sesquiterpenes and monoterpenes (these three species are very close). The study of the antioxidant activity showed that all the EOs tested have a high capacity for scavenging free radicals from DPPH. The EOs of Laurus nobilis and Pistacia lentiscus showed the highest activity, 76.84% and 71.53%, respectively, followed by Cedrus atlantica EO (62.38%) and Chamaemelum nobile (47.98%) then Citrus aurantium EO (14.70%). Antimicrobial activity EO was tested against eight bacterial strains and eight fungal strains; the results showed that EOs exhibit significant bactericidal and fungicidal activities against all the microorganisms tested, of which the MICs of the bacterial strains start with 5 mg/mL, while the MICs of the fungal strains are between 0.60 mg/mL and 5 mg/mL. Thus, these EOs rich in antimicrobial and antioxidant components can serve as a natural alternative; this confirms their use as additives in cosmetics.

Identification of Compounds of Crocus sativus by GC-MS and HPLC/UV-ESI-MS and Evaluation of Their Antioxidant, Antimicrobial, Anticoagulant, and Antidiabetic Properties

In order to valorize the species Crocus sativus from Morocco and to prepare new products with high added value that can be used in the food and pharmaceutical industry, our interest was focused on the phytochemical characterization and the biological and pharmacological properties of the stigmas of this plant. For this purpose, the essential oil of this species, extracted by hydrodistillation and then analyzed by GC-MS, revealed a predominance of phorone (12.90%); (R)-(-)-2,2-dimethyl-1,3-dioxolane-4-methanol (11.65%); isopropyl palmitate (9.68%); dihydro-β-ionone (8.62%); safranal (6.39%); trans-β-ionone (4.81%); 4-keto-isophorone (4.72%); and 1-eicosanol (4.55%) as the major compounds. The extraction of phenolic compounds was performed by decoction and Soxhlet extraction. The results of the determination of flavonoids, total polyphenols, condensed tannins, and hydrolyzable tannins determined by spectrophotometric methods on aqueous and organic extracts have proved the richness of Crocus sativus in phenolic compounds. Chromatographic analysis by HPLC/UV-ESI-MS of Crocus sativus extracts revealed the presence of crocin, picrocrocin, crocetin, and safranal molecules specific to this species. The study of antioxidant activity by three methods (DPPH, FRAP, and total antioxidant capacity) has proved that C. sativus is a potential source of natural antioxidants. Antimicrobial activity of the aqueous extract (E0) was investigated by microdilution on a microplate. The results have revealed the efficacy of the aqueous extract against Acinetobacter baumannii and Shigella sp. with MIC ≤ 600 µg/mL and against Aspergillus niger, Candida kyfer, and Candida parapsilosis with MIC = 2500 µg/mL. Measurements of pro-thrombin time (PT) and activated partial thromboplastin time (aPTT) in citrated plasma obtained from routine healthy blood donors were used to determine the anticoagulant activity of aqueous extract (E0). The anticoagulant activity of the extract (E0) studied showed that this extract can significantly prolong the partial thromboplastin time (p < 0.001) with a 359 µg/mL concentration. The antihyperglycemic effect of aqueous extract was studied in albino Wistar rats. The aqueous extract (E0) showed strong in vitro inhibitory activity of α-amylase and α-glucosidase compared with acarbose. Thus, it very significantly inhibited postprandial hyperglycemia in albino Wistar rats. According to the demonstrated results, we can affirm the richness of Crocus sativus stigmas in bioactive molecules and its use in traditional medicine.

“…The essential oil extracted from Lamiaceae species is proved by many studies to be of a high quality, and it was used by multiple industries, such as pharmaceutic and cosmetic, but especially in traditional medicine in many rural communities [ 1 , 2 , 3 ]. The commerce of plants and essential oils has increased considerably in both developed and developing countries [ 4 ]. In Lamiaceae species, the majority of the utilized material is derived from wild populations that have frequently been developed in disturbed environments [ 5 , 6 , 7 ].…”

The lavender Lavandula multifida L., a medicinal plant grown in arid regions of Tunisia, was recently considered an endangered species; thus, its habitats regressed to some difficult zones in terms of access, such as the watershed of Oued Agareb in central-eastern Tunisia. This species was recorded only in deep and narrow shady Wadi of the watershed and benefited from protection against overgrazing, erosion and sunlight. L. multifida was rarely observed in an open area, such as a plateau or large-bed valley. The plant’s metabolism is linked to its response to environmental conditions, which is of particular interest to understanding the components of the considered population of L. multifida. Consequently, biochemical and antimicrobial analyses have been evaluated. Using gas chromatography-mass spectrometry (GC-MS) analysis reveals that among the 58 compounds identified in L. multifida essential oil extracted from aboveground plant tissues, camphor was the major component (15.68%), followed by 1,8-cineole (14.14%) and alpha-pinene (13.82%). Moreover, it has been observed that Escherichia coli was more susceptible than Staphylococcus aureus to the antimicrobial properties of L. multifida essential oil, while in the case of camphor, S. aureus was more susceptible than E. coli. The protected population of L. multifida exhibits a distinctive vegetative development and growth cycle, resulting in specific secondary metabolites and distinguished antimicrobial activity.
