The thrips, Frankliniella schultzei, and green peach aphid, Myzus persicae, cause direct damage to plants of economic importance and transmit phytoviruses, causing large economic losses. Chemical constituents of essential oils present a wide range of biological activities. The aim of this work was to evaluate insecticidal activity of essential oil from citronella grass, Cymbopogon winterianus, on F. schultzei and M. persicae. This essential oil was obtained by steam distillation and components were identified by GC/FID and GC/MS. A Potter spray tower was used to spray insects with the essential oil. The major constituents are geraniol (28.62%), citronellal (23.62%) and citronellol (17.10%). Essential oil of C. winterianus at 1% (w v-1) causes mortality in F. schultzei and M. persicae at 34.3% and 96.9%, respectively. The LC50 value for M. persicae was 0.36% and LC90 0.66%. Thus, citronella grass essential oil at 1% (w v-1) is more toxic to M. persicae than F. schultzei. This essential oil shows promise for developing pesticides to manage M. persicae.

Murraya microphylla is the most closely related species to M. koenigii (Curry tree). Inspired by the traditional effects of M. koenigii, the antioxidant, anti-inflammatory, and cytotoxic activities of the essential oil and extracts of M. microphylla were evaluated for the first time. The light petroleum and chloroform extracts were found to be able to scavenge DPPH free radicals, inhibit linoleic acid peroxidation, and nitric oxide production, as well as to present cytotoxicity to the human cancer cell lines HepG2, Bel7402, Bel7403, and Hela, but the essential oil only showed moderate activities. Chemical analysis of the active extracts by LC-DAD-MSn indicated that carbazole alkaloids were the main constituents. GC-MS analysis of the essential oil resulted in identification of 91 constituents, representing 96.9% of the total oil, with ( E)-caryophyllene (18.4%) and terpinen-4-ol (12.6%) as the major constituents. These results demonstrate that M. microphylla has similar biological activities, as well as chemical constituents to M. koenigii, and the carbazole alkaloids were disclosed to be the main potential active components. A promising development as a flavor and potential therapeutic agent could thus be predicated for this plant.

Abstract Medicinal plants are potential sources of natural compounds with biological activities and therefore attract the attention of researchers worldwide. Citrus oils are a complex mixture of more than a hundred components of differing chemical natures. Qualitative and quantitative analysis by gas chromatography coupled with mass spectrometry (GCMS) of the Citrus reticulata essential oil collected from El Hadaïk, Skikda City (Algeria), identified 28 compounds representing a total of 99.41%. The essential oil is constituted mainly of: D-Limonene (85.10%), Sabinene (2.49%), Linalyl acetate (2.00%), Copaene (1.80%) et α-Pinene (1.75%) totaling approximately 93.14%. The essential oil was also analyzed by Fourier transform infrared spectroscopy analysis (FTIR). FTIR spectroscopy allowed us to identify 10 volatile compounds and indicated that the functional groups of the essential oils are C-H (Alkene), C-H (aromatic) and C=C. The obtained results have shown that the essential oil can be fully utilized for pharmacy, cosmetology and industry.

Till date, no study has ever looked into the effect of extraction method on the chemical constituents of the essential oil of Helichrysum petiolare. This study therefore evaluated the effect of hydrodistillation and solvent free microwave extraction (SFME) methods on the chemical constituents of H. petiolare derived essential oils. The SFME derived essential oil was deep yellow and of higher yield than the pale yellow essential oil obtained through the hydrodistillation. There were substantial amounts of monoterpenes, monoterpene alcohols, sesquiterpenes, and sesquiterpene alcohols in both essential oils obtained. The SFME derived essential oil had 62 compounds as against the 52 derived through hydrodistillation. The SFME derived essential oil can therefore be suggested to be of better quality than of the hydrodistillation method. The compounds obtained in the essential oils have high pharmaceutical and cosmetic values, and as observed in this study, their quantity is dependent on method of extraction.

Insecticidal Action

Essential oils are compounds produced by secondary plant metabolites and are found in leaf trichomes, moreover, they are characteristic because they present strong odors and present biological activities. Thus, the objective of this work was to evaluate the insecticidal action of Mesosphaerum suaveolens essential oil against nymphs of Nauphoeta cinerea as well as to characterize the chemical constituents present in it. The EO was extracted by means of hydrodistillation and its chemical characterization was done by Gas Chromatography coupled to Mass Spectrometry (GC/MS). For the biological assay against cockroaches, nymphs of 20 days old were selected for which they were submitted to different concentrations (50 - 1000 μg/mL oil per air) and mortality was evaluated over 48 hours of EO exposure. As a positive control, ethanol (C2H6O) was used. Have been identified 44 compounds in EO, with β-Caryophyllene (18.57%), sabinene (15.94%) and spatulenol (11.09%) being the major compounds of EO. This showed no activity against the nymphs at any of the concentrations, whereas the positive control caused mortality at all concentrations tested. Thus, the essential oil of M. suaveolens does not present insecticidal properties in low concentrations against the cockroach.

Nutmeg Essential Oil

Myristica fragrans Houtt., commonly known as nutmeg, is an Indonesian indigenous dioecious evergreen tree which contains 5-15% volatile oil. The oil is usually produced from the seed or mace.  Nutmeg oil has been extensively utilized in aromatherapy, natural medicine, and the perfume industry. This article provides an overview of the chemical compounds, biological potency, and toxic effects of nutmeg essential oil compiled from recent literature (2000–2020). Nutmeg oil mainly comprises monoterpenes and phenylpropanoids. Several reports on gas chromatography-mass spectrophotometry analysis of nutmeg oil showed that there were 27–38 chemical constituents detected at various concentrations. Many secondary metabolites of nutmeg oil reported to show biological activities that possibly substantiate its utilization in natural medicine. Numerous studies reported the biological activities of this volatile oil such as antioxidant, analgesic, antiinflammation, anticonvulsant, antibacterial, antiparasitic, insecticidal, and anticancer activity. But large intake of nutmeg oil could cause intoxication which is shown through symptoms in cardiovascular, central nervous system, anticholinergic, and local effects in the stomach. These symptoms are mainly attributed to the effect of myristicin, safrole, and elemicin overdose. This updated review paper intends to attract more attention to nutmeg oil and its potential to be developed into a medicinal product for the prophylaxis and therapy of diseases.
