Basil (Ocimum basilicum L.) is an aromatic plant, well known for its characteristic scent and healing properties, which has a wide application, from cooking to alternative medicine. The objective of this work was to evaluate the chemical composition, antimicrobial and antioxidant activity of basil essential oil obtained by hydrodistillation, microwave-assisted hydrodistillation and solvent-free microwave-assisted hydrodistillation. Gas chromatography analysis showed that the main components present in all three essential oils were linalool (30.3-58.2%) and epi-a-cadinol (5.6-7.3%). The distillation method mainly affected the content of terpenes, and aromatic compounds. The essential oils expressed good antimicrobial activity, most effective against Escherichia coli ATCC 25922, while the Pseudomonas aeruginosa ATCC 27853 was the most resistant strain. Good antioxidant activity was established after 120 min of incubation for all obtained essential oils with a significant difference regarding the applied distillation method. The results showed a great influence of the distillation method on the chemical composition, detected compounds, as well as antioxidant potential and antimicrobial activity of basil essential oils. The use of microwave assisted hydrodistillation has shown a significant difference in oil yield, energy consumption and environmental impact, which makes it a more suitable distillation process compared to conventional hydrodistillation.

Algerian flora contains a wide range of aromatic plants of great therapeutic interest thanks to their biologically active secondary metabolites which makes them a subject of scientific interest. In this work, we were interested in Ocimum basilicum L. of Lamiaceae family cultivated and harvested in Biskra city located at South-East of Algeria. Phytochemical screening has been per-formed to reveal the presence of flavonoids, tannins, coumarins, essential oil, and other phytochemicals. The contents of total polyphenols, total flavonoids and total tannins have been determined. The obtained essential oil and extracts have been the subject of antibacterial and antioxidant assays. Our outcomes confirmed that Ocimum basilicum L. has a multiplicity of potential phytochemicals with a considerable amount and can be used as an alternative natural source of antioxidant and antibacterial components.

“…The short-term heating of the water in the plant material expands the plant cells causing the plant cells and oil producing glands to release the oil from the plant material [ 9 ]. SFME method has widely been employed in the extraction of oils from Melalaica leucadendra L. [ 13 ], Ocimum basilicum L. [ 14 ], Kananga odorata [ 15 ], Pogostemon cabin [ 16 ], Cuminumcyminum L. and Zanthoxylum bungeanum Maxim [ 17 ], and many others. However, until now, there has been no studies on the comparison of the quality and yield of essential oils obtained from H. arborescens leaves using hydrodistillation and SFME methods.…”

This study was aimed at comparing the essential oils obtained from Heteromorpha arborescens leaves by Solvent-Free Microwave Extraction (SFME) and Hydrodistillation (HD) methods in terms of their chemical compositions, yield, CO2 emission, and energy consumption. The solvent-free microwave extraction method indicated a higher oil yield of 0.7 mL/200 g (0.35%) as compared to 0.59 mL/200 g (0.295%) obtained through hydrodistillation. GC-MS analysis of the oils revealed a total of 52 chemical components from both methods with the presence of 35 (96.52%) and 30 (71.15%) chemical constituents for HD and SFME, respectively. The major constituents observed in the essential oil extracted by SFME methods include α-pinene (6%), D-limonene (11.27%), β-ocimene (9.09%), β-phellandrene (6.33%), β-mycene (8.49%), caryophyllene (5.96%), and camphene (4.28%). However, in the hydrodistillation method, the oil was majorly composed of a-pinene (4.41%), β-pinene (10.68%), β-ocimene (6.30%), germacrene-D (5.09%), humulene (5.55%), and α-elemene (6.18%). The SFME method was better in terms of saving energy (0.25 kWh against 4.2 kWh of energy consumed), reduced CO2 emission (200 g against 3360 g of CO2), a higher yield, and better quality of essential oil due to the presence of higher valuable oxygenated compounds (8.52%) against that of the hydrodistillation method (2.96%). The SFME method is, therefore, a good alternative for extracting the oils of H. arborescens leaves since the essential oil yield is higher with more oxygenated compounds, considerable energy savings, lower cost, and reduced environmental burden at substantially reduced extraction time (30 min as opposed to 180 min).
