The essential oil from the aerial parts of Tanacetum nubigenum Wallich ex DC collected from the Milam glacier moraine showed the presence of 73 compounds, of which 69, representing 87.9% of the total oil, have been identified, with bornyl acetate (39.7%), borneol (10.6%), ( E)-β-farnesene (6.6%) and 1,8-cineole (5.8%) as major constituents, while the oil from the plant material from the Pindari glacier area contained a total of 81 compounds, of which 77 have been identified. This oil was characterized by the presence of (3 R, 6 R)-linalool oxide acetate (69.4%), β-eudesmol (3.2%), selin-11-en-4α-ol (3.2%) and (3.2% and 1.2%, respectively) for compounds ( E) and ( Z)-2-(2,4-hexadiynylidene)-1,6-dioxospiro [4,4] non-3-ene, respectively. The major constituents of the essential oils from the aerial parts were separated and characterized by GC, GC/MS and 1D- and 2D-NMR spectroscopy. The chemical differences between the two essential oils place them as distinct chemical races or chemotypes.

Abstract. Ounoughi A, Ramdani M, Lograda  T, Chalard P, Figueredo G. 2020. Chemotypes and antibacterial activities of Inula viscosa essential oils from Algeria. Biodiversitas 21: 1504-1517. The aim of this work is to investigate the chemical composition and the antibacterial activities of the essential oils from Inula viscosa (L.) Aiton. Samples were collected in the flowering stage, from different localities in Algeria. The aerial parts of I. viscosa were submitted to a hydro distillation. The chemical composition of the essential oil was analyzed by GC and GC/MS. The antibacterial activity of the essential oils was evaluated using the disc diffusion method against fifteen bacterial species. Fifty-eight compounds representing 98.93 ± 2.03% of the total oil was identified in I. viscosa. It was found that the chemical composition was dominated by the presence of the following major products: polygodial (19.8 ± 16.97%), phytol (12.3 ± 9.77%), fokienol (6.01 ± 3.43%), intermedeol neo (5.09 ± 2.38%), caryophyllene oxide (4.91 ± 3.03%), nerolidol-Z (4.46 ± 5.46%), nerolidol-E (4.24 ± 8.07%) and α-ionone iso methyl-E (3.72 ± 2.26%). The essential oil of I. viscosa has moderate activity against the bacteria tested. In contrast, the Escherichia coli ATCC 25922, Pseudomonon syringae ATCC 53543 and Enterococcus faecalis ATCC 49452 strains are resistant to I. viscosa essential oils. The phytochemical study of I. viscosa showed that it is rich in terpene compounds, with polygodial and phytol as major components. Three distinct chemotypes are highlighted. The (Polygodial-Intermedeol-neo-Phytol) chemotype of Salah Bey population and two chemotypes with Fokinol-polygodial and Fokinol-phytol. Moderate antibacterial activities of essential oils against the bacteria tested were found.

Water-distilled essential oil from Clinopodium chinense (Labiatae) aerial parts at the flowering stage was analyzed by gas chromatography–mass spectrometry. Thirty-five compounds, accounting for 99.18% of the total oil, were identified, and the main components of the essential oil of C. chinense were spathulenol (18.54%), piperitone (18.9%), caryophyllene (12.04%), and bornyl acetate (8.14%). Based on bioactivity-directed fractionation, bornyl acetate, caryophyllene, and piperitone were identified from the essential oil. The essential oil possessed fumigant toxicity against booklice (Liposcelis bostrychophila) with a 50% lethal concentration (LC50) value of 423.39 μg/liter, while the isolated constituents, bornyl acetate and piperitone, had LC50 values of 351.69 and 311.12 μg/liter against booklice, respectively. The essential oil also exhibited contact toxicity against L. bostrychophila with an LC50 value of 215.25 μg/cm2. Bornyl acetate, caryophyllene, and piperitone exhibited acute toxicity against booklice with LC50 values of 321.42, 275.00, and 139.74 μg/cm2, respectively. The results indicated that the essential oil and its isolated constituents have potential for development into natural insecticides or fumigants for control of insects in stored grains.

The main objective of this study was to analyze the essential oil composition of cultivated lavandin (Lavandula x intermedia Emeric ex Loisel., Lamiaceae) from Republic of Macedonia and to evaluate the influence of the drying time of plant material and the distillation duration on the oil composition. Four different essential oils were obtained by hydrodistillation in a Clevenger type apparatus from freshly harvested and air dried flowers of lavandin and varying in distillation time (30 min and 2 h). Fifty-six compounds were identified by GC/ FID/MS representing 96.57% to 98.23% of the total oil. Prevailing constituents in all tested oils were linalool, borneol and terpinene-4-ol, present in amounts from 35.23 to 42.24%, 12.28 to 16.68% and 4.44 to 5.62%, respectively. The content of 1,8-cineole varied from 3.99% to 8.42% while that of camphor was between 5.96% and 7.04%. Linalyl acetate was present in amounts from 1.26% to 3.21%. Unexpectedly, the duration of distillation insignificantly influenced the essential oil composition. Few differences, mainly in the content of borneol (13.71% and 16.68% in the oil from fresh and dried flowers, respectively) were recorded in the essential oils obtained by 30 minutes distillation, while the content of the other constituents was almost unchanged. However, the isolated essential oils of lavandin did not comply with the international standards requirements for the lavandin essential oil composition.
