Identification of chemical components from essential oils and aqueous extracts of some medicinal plants and their nematicidal effects on Meloidogyne incognita was written by Ardakani, A. S.;Hosseininejad, S. A.. And the article was included in Journal of Basic & Applied Zoology in 2022.HPLC of Formula: 105-87-3 This article mentions the following:
Essential oils from aerial parts of Achillea wilhelmsii, Tanacetum polycephalum and Teucrium polium were isolated by using Clevenger-type apparatus and tested at different concentrations for their nematicidal activity against the second stage juvenile (J2) of Meloidogyne incognita in vitro condition. The chem. components of the essential oils and seed extracts of each plant (0.2 g) were extracted with maceration with methanol/acetic acid mixture (85:15, volume/volume). Anal. was done by Gas Chromatog., GC-Mass Spectrometry) and HPLC. Identified chem. components were tested after this on J2 of M. incognitain. NMR spectroscopy was done to investigate the properties of organic mols. by drawing their spectrum using Broker AVANCE AQS-300 MHz. Significant difference was achieved on nematicidal activity of essential oils based on the plant species and oil concentrations GC and GC-MS led to identification of 41, 39 and 45 major compounds from T. polium, T. polycephalum and A. wilhelmsii oils, resp. A number of 10 components with different ranges of percentage were recorded in all of the tested plants oils. Use of HPLC resulted in identification of 4, 3 and 2 chem. compounds in the extracts of A. wilhelmsii, T. polycephalum and T. polium, resp. The nematicidal activity of com. polyphenols at the concentration of 1100 ppm showed 58.3, 48.9, 28.2 and 26.8 percentages J2 mortalities by catechin, coumarin, gallic acid and chlorogenic, resp. Nematotoxicity test of com. terpenoids showed the highest J2 mortalities (more than 80%), in concentrations of 100 and 200 ppm limonene, β-pinene and α-pinene. However, it was less than 30% of J2 mortality caused by terpinen-4-ol, α-terpineol and linalool. Compounds such as Limonene, β-pinene and α-pinene were detected in all of the tested plants, A. wilhelmsii, T. polycephalum and T. polium, having an effective nematicidal action vs. terpinen-4-ol, α-terpineol and linalool. In the experiment, the researchers used many compounds, for example, (E)-3,7-Dimethylocta-2,6-dien-1-yl acetate (cas: 105-87-3HPLC of Formula: 105-87-3).
(E)-3,7-Dimethylocta-2,6-dien-1-yl acetate (cas: 105-87-3) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.HPLC of Formula: 105-87-3
