Having high cytotoxicity cell line effect, Cinnamomum zeylanicum Blume essential oil offers a novel approach to the chemotherapy treatment. In order to enhance its quantity/purity, the experimental conditions to produce essential oil should be more exploited. Steam distillation was used to isolate essential oil, and its conditions’ optimization was carried out with the surface-response methodology. The maximum amount (2.6 g/100 g d.b.) was obtained under minimum condensation water flow (0.8 mL/min), a sample size of 6.5 cm, a saline solution concentration of 262.5 g/L, and five washings. The produced essential oil contains >77% of polyphenols. In vitro cytotoxicity was examined using an MTT assay against HeLa and Raji cell lines. The essential oil’s capability to inhibit the proliferation of HeLa and Raji cell lines was studied under some conditions presenting IC50 values of 0.13 and 0.57 μg/mL, respectively. The essential oil was evaluated for its potential as an antioxidant by using in vitro models, such as phosphomolybdenum, DPPH, and H2O2 methods, in comparison with the synthetic antioxidant BHT (butylated hydroxytoluene) and ascorbic acid (vitamin C) as positive controls. The ammonium phosphomolybdate potency in the present study is of the order of 108.75 ± 32.63 mg of essential oil/equivalent to 1 mg of vitamin C in terms of antioxidant power, and the antioxidant activity of DPPH-H2O2 was 21.3% and 55.2%, respectively. The Cinnamomum zeylanicum Blume essential oil (CEO) covers important antioxidant and antiproliferative effects. This can be attributed to the presence of few minor and major phenolic compounds.

“…Despite the numerous extraction methods used to obtain EOs from natural raw plant material, only four methods, such as (i) hydrodistillation, (ii) steam distillation, (iii) dry distillation, and (iv) mechanical processes, are considered in the European Pharmacopoeia and the International Standard Organization on Essential oils (ISO 9235:2013) [4]. e EO can undergo physical treatments, which do not result in any significant change in its composition (e.g., filtration, decantation, and centrifugation).…”

Among botanical extracts used as insecticides, essential oils (EOs) are promising alternatives to chemical insecticides. EOs are synthesized by plants, and they play a key role in plant signaling processes including also attractiveness toward pollinators and beneficial insects. Plant species producing essential oils (over 17,000 species) are called aromatic plants and are distributed worldwide. Our review aims to evaluate research studies published in the last 15 years concerning the use of EOs in stored product protection. More than 50% of the retrieved manuscripts have been published by authors from Eastern countries (Iran, China, India, and Pakistan), investigating different aspects related to insect pest management (exposure route, effect on the target pest, and mode of action). Coleoptera was the most studied insect order (85.41%) followed by Lepidoptera (11.49%), whereas few studies targeted new emerging pests (e.g., Psocoptera). Almost all the trials were carried out under laboratory conditions, while no experiments were conducted under real operating conditions. Future research studies concerning the use of EOs as insecticides should focus on the development of insecticide formulations which could be successfully applied to different production realities.

“…Determining the chemical constitution of the tested material is also an important step in those bioassays, to identify the specific allelopathic substances involved (Verdeguer et al 2011;Magalhães et al, 2012). The most widely used analytical methods are highperformance liquid chromatography and GC-MS gas chromatography-mass spectrometry (Zuzarte and Salgueiro, 2015). Allelopathy studies of Zingiberaceae family are rare, and little is known about C. zedoaria, except that it is welladapted to tropical conditions, is easily propagated, and produces essential oils with yields varying from 0.38% to 1.4% (Angel et al 2014).…”

The contamination of food, water, and soils by herbicides, as well as the growing resistance of weeds to these products, has increased demands for alternative methods of weed control that have less impact on the environment and human health. Curcuma zedoaria (zedoary), a species of the Zingiberaceae family, is a promising plant for alternative weed control as it produces an essential oil with herbicidal action. We evaluated the chemical composition of C. zedoaria essential oil and its allelopathic effects on the vigor and germination of lettuce achenes and tomato seeds. The essential oil was extracted from the plant rhizome by hydrodistillation and subjected to gas chromatography-mass spectrometry to identify its component chemical compounds. Bioassays to evaluate allelopathic potential were performed in gerbox-type containers maintained in a refrigerated biochemical oxygen demand incubator at 25°C. The treatments consisted of five essential oil concentrations (0.00, 0.25, 0.50, 0.75, and 1.00%) and two bioindicators (lettuce and tomato). C. zedoaria essential oil comprises monoterpene hydrocarbons (4.63%), oxygenated monoterpenes (25.88%), sesquiterpene hydrocarbons (21.95%), and oxygenated sesquiterpenes (47.54%). The major compounds encountered were 1.8-cineole (15.75%) and epi-curzerenone (18.20%). We believe that the isolated effect of these compounds or the synergism between them may have influenced the observed results. Germination was inhibited in both bioindicator species, but the percentage inhibition was greater in lettuce achenes. Germination rates decreased in lettuce and tomato with increasing concentrations of essential oil, and bioindicator growth was slowed. The root system was more heavily damaged than the hypocotyl, especially in tomato compared to lettuce. These preliminary results indicate that C. zedoaria essential oil has allelopathic effects on seed germination and seedling growth and thus shows potential for weed control.
