This exploratory investigation aimed to determine the chemical composition and evaluate the biological properties of Matricaria chamomilla L. essential oils. The results showed that the essential oils exhibited antioxidant, antimicrobial, and antidiabetic activities. Further research on the bioactive compounds is necessary.
This exploratory investigation aimed to determine the chemical composition and evaluate some biological properties, such as antioxidant, anti-inflammatory, antidiabetic, and antimicrobial activities, of Matricaria chamomilla L. essential oils (EOs). EOs of M. chamomilla were obtained by hydrodistillation and phytochemical screening was performed by gas chromatography-mass spectrophotometry (GC-MS). The antimicrobial activities were tested against different pathogenic strains of microorganisms by using disc diffusion assay, the minimum inhibitory concentration (MIC), and minimum bactericidal concentration (MBC) methods. The antidiabetic activity was performed in vitro using the enzyme inhibition test. The antioxidant activity of EOs was tested using the free radical scavenging ability (DPPH method), ferrous ion chelating (FIC) ability, and beta-carotene bleaching assay. The anti-inflammatory effects were tested in vivo using the carrageenan-induced paw edema method and in vitro using the inhibition of the lipoxygenase test. The analysis of the phytochemical composition by GC-MS revealed that camphor (16.42%) was the major compound of EOs, followed by 3-carene (9.95%), beta-myrcene (8.01%), and chamazulene (6.54%). MCEO, honey, and their mixture exhibited antioxidant activity against the DPPH assay (IC50 ranging from 533.89 +/- 15.05 mu g/mL to 1945.38 +/- 12.71 mu g/mL). The mixture exhibited the best radical scavenging activity, with an IC50 of 533.89 +/- 15.05 mu g/mL. As antidiabetic effect, EO presented the best values against alpha-glucosidase (265.57 +/- 0.03 mu g/mL) and alpha-amylase (121.44 +/- 0.05 mu g/mL). The EOs and honey mixture at a dose of 100 mg/kg exhibited a high anti-inflammatory effect, with 63.75% edema inhibition after 3 h. The impact of EOs on the studied species showed an excellent antimicrobial (Staphylococcus aureus ATCC 29213 (22.97 +/- 0.16 mm)), antifungal (Aspergillus niger (18.13 +/- 0.18 mm)) and anti-yeast (Candida albicans (21.07 +/- 0.24 mm) effect against all the tested strains. The results obtained indicate that the EOs of M. chamomilla could be a potential drug target against diabetes, inflammation and microbial infections; however, further investigations to assess their bioactive molecules individually and in combination are greatly required.
