Background Ocimum americanum L. (O. americanum) and Ocimum basilicum L. (O. basilicum) are highly valued aromatic medicinal plants. Their leaves are widely used as spices in traditional cuisine. Their essential oils (EOs) are extensively used in food, cosmetic, and pharmaceutical industries. This study aimed to investigate the main chemical profiles of O. americanum and O. basilicum leaf EOs and assess their effects on antibacterial, antioxidant, and larvicidal properties. Methods EOs were extracted from the leaves of O. basilicum and O. americanum using steam distillation in a Clevenger-type apparatus. The chemical constituents of the EOs were analyzed using gas chromatography–mass spectrometry. 2,2-Diphenyl-1-picrylhydrazyl (DPPH), ferric reducing antioxidant power (FRAP), and metal-chelating techniques were used to assess the free-radical scavenging capability of the oils. The extracted oils were also tested for their antibacterial activities via a disk-diffusion test and the broth microdilution method. Furthermore, the mosquito larvicidal (Aedes aegypti) activity was tested using standard protocols. Results Camphor (33.869%), limonene (7.215%), longifolene (6.727%), caryophyllene (5.500%), and isoledene (5.472%) were the major compounds in O. americanum leaf EO. The EO yield was 0.4%, and citral (19.557%), estragole (18.582%) camphor (9.224%) and caryophyllene (3.009%) were the major compounds found among the 37 chemical constituents identified in O. basilicum oil. O. basilicum exhibited a more potent antioxidant activity in DPPH, FRAP, and 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid tests than O. americanum. The zones of inhibition and minimum inhibitory concentration of the oils in the microdilution and disk diffusion methods were 8.00 ± 0.19 mm to 26.43 ± 2.19 mm and 3.12–100 µg/mL, respectively. At 400 ppm, O. basilicum and O. americanum EOs demonstrated larvicidal activity, with mortality ratios of 73.60% ± 0.89% and 78.00% ± 1.00%, respectively. Furthermore, after 30 min of exposure to O. americanum and O. basilicum EOs, the larval death rates were 73.60% ± 0.89% and 78.00% ± 1.00%, respectively. Conclusions The findings revealed that the EOs extracted from the leaves of O. basilicum and O. americanum exhibited reasonable antioxidant, antibacterial, and mosquito larvicidal potentials, and can be used as alternative medicine for the treatment of human health and larvicidal mosquito control.

Background: Ocimum americanum L. and Ocimum basilicum L. are highly valued aromatic medicinal plants. The leaves of O. basilicum and O. americanum are widely used as spices in traditional cuisine. Its essential oil is extensively used in the food, cosmetic, and pharmaceutical industries. The purpose of this study is to investigate the main chemical profile of O. americanum and O. basilicum leaf essential oils and to assess their effects on antibacterial, antioxidant, and larvicidal properties. Methods:Essential oils were extracted from the leaves of O. basilicum and O. americanum using steam distillation in a Clevenger-type apparatus. The chemical constituents of the essential oils (EO) were analyzed by gas chromatography-mass spectrometry (GC-MS). DPPH, FRAP, and metal chelating techniques were used to assess the free radical scavenging ability of the oils. The extracted oil was also tested for its antibacterial activities by a disc-diffusion test and the broth microdilution method. Furthermore, the mosquito larvicidal activity was tested using standard protocols. Results:Camphor (33.869%), limonene (7.215%), longifolene (6.727%), caryophyllene (5.500%), and isoledene (5.472%) were identified as the five major compounds in O. americanumleaf essential oil. The essential oil yield was 0.4%, and citral (19.557%), estragole (18.582%), linalool (17.605%), and camphor (9.224%) were the major compounds found among the 37 chemical constituents identified in O. basilicum oil. O. basilicum exhibited more potent antioxidant activity in DPPH, FRAP, and ABTS tests than O. americanum. The zones of inhibition and MIC of the oils in the microdilution and disc diffusion methods were 8.00±0.19 to 26.43±2.19 mm and 3.12 – 100 μg/mL, respectively. At 400 ppm, O. basilicum and O. americanum demonstrated larvicidal activity with mortality ratios of 73.60±0.89 and 78.00±1.00%, respectively. Furthermore, after 30 min of exposure, the larval death rate was 73.60±0.89 and 78.00±1.00% for O. americanum and O. basilicumrespectively. Conclusions:These findings revealed that essential oils extracted from the leaves of O. basilicum and O. americanum exhibited reasonable antioxidant, antibacterial, and mosquito larvicidal potentials that can be used as alternative medicine in treating human health and larvicidal mosquito control.

“…Considering these benefits and effects, basil has multiple interesting uses in the food industries, perfume industry, traditional medicine industry as well as pharmaceutical industry. O. basilicum is a very common plant that is grown in aquaponics or more specifically in coupled aquaponic conditions [14]. Basil leaves develop an unmistakable and distinctive scent via peculiar oil glands, and basil is therefore considered as a very useful herb [15].…”

Greenhouse and aquaponic productions of basil (Ocimum basilicum L.) are well established, but the comparison between these two methods is not studied in detail. A study was conducted to evaluate the performance of basil in both aquaponic and soil systems under greenhouse conditions. The plants were raised in aquaponic beds with ornamental fish and a set of plants was raised in soil pots under a greenhouse setup. The studied parameters were morphological, biochemical and antioxidant levels. In order to analyze the stress effects of an aquaponic system on plant defense mechanism, two different antioxidant enzymes (catalase and peroxidase) were analyzed. Water quality parameters were monitored during the entire study period. Based on the results, there was a significant increase in growth parameters in the aquaponic system when compared to the conventional greenhouse cultivation of basil plants. The photosynthetic parameters showed a decline in the aquaponic system, but the biochemical parameters showed an enhancement in the aquaponic system of growing basil plants. The antioxidants exhibited a significant increase in the aquaponic system, which suggests a water stress effect on the plants induced by the aquaponic growing system. From the results of this study, it can be concluded that the aquaponic system is the best suitable method for basil production in the UAE condition.
