  • contact toxicity and repellent efficacy of valerianaceae spp to three stored product insects and synergistic interactions between two major compounds camphene and Bornyl Acetate
    Ecotoxicology and Environmental Safety, 2020
    Co-Authors: Yixi Feng, Yang Wang, Zhufeng Geng, Di Zhang, Borjigidai Almaz, Shushan Du

    Abstract:

    Abstract In this work, the essential oil (EO) and supercritical CO2 fluid extract (SF extract) of four Valerianaceae plants (Valeriana officinalis L., Valeriana officinalis L. var. latifolia Miq., Valeriana jatamansi Jones and Nardostachys chinensis Bat.) were chemically characterized. GC-MS analysis identified 74 compounds, representing 35.2%–82.4% of the total EOs and SF extracts. The EO was dominated by low-molecular-weight components while the SF extract was rich in fatty acids. Bornyl Acetate and camphene were the characteristic compounds in EO and SF extracts. The efficacy of six extracts against three stored-product insects was investigated. In contact assays, V. officinalis exhibited strongest toxicity to red flour beetle (LD50 = 10.0 μg/adult), and V. jatamansi EO was the most active one against the cigarette beetle (LD50 = 17.6 μg/adult), while V. officinalis var. latifolia EO showed outstanding efficacy against the booklouse (LD50 = 40.2 μg/cm2). Binary mixtures of two major compounds (camphene and Bornyl Acetate) were assessed for the contact toxicity to the red flour beetle. Additive effect existed in the natural proportion of V. officinalis, and synergism was observed in that of V. officinalis var. latifolia. This work confirmed the insecticidal efficacy of the species of the Valerianaceae family, and it would offer some information for the development of botanical insecticide.

  • efficacy of Bornyl Acetate and camphene from valeriana officinalis essential oil against two storage insects
    Environmental Science and Pollution Research, 2019
    Co-Authors: Yixi Feng, Yang Wang, Zhenyang Chen, Shushan Du

    Abstract:

    : The essential oil was extracted from the roots of Valeriana officinalis L. by hydrodistillation. The qualitative and quantitative analysis of its chemical constituents was conducted on GC-MS and GC-FID in this study. Seventeen compounds were detected and the major constituents included Bornyl Acetate (48.2%) and camphene (13.8%). The toxic and repellent effects of the essential oil and its two major constituents were evaluated on Liposcelis bostrychophila and Tribolium castaneum. The results of bioassays indicated that the essential oil showed the promising fumigant and contact toxicity against L. bostrychophila (LC50 = 2.8 mg/L air and LD50 = 50.9 μg/cm2, respectively) and the notable contact effect on T. castaneum (LD50 = 10.0 μg/adult). Meanwhile, the essential oil showed comparable repellent effect on T. castaneum at all testing concentrations. Bornyl Acetate and camphene also exhibited strong fumigant and contact toxicity against both species of pests (LC50 = 1.1, 10.1 mg/L air and LD50 = 32.9, 701.3 μg/cm2 for L. bostrychophila; > 126.3, 4.1 mg/L air, and 66.0, 21.6 μg/adult for T. castaneum). Bornyl Acetate and camphene showed moderate repellent effect on T. castaneum and conversely showed attractant effect on L. bostrychophila. This work highlights the insecticidal potential of V. officinalis, which has been noted as a traditional medicinal plant.

  • in situ analysis of chiral components of pichtae essential oil by means of roa spectroscopy experimental and theoretical raman and roa spectra of Bornyl Acetate
    Journal of Raman Spectroscopy, 2012
    Co-Authors: Katarzyna Chruszczlipska, Ewan W Blanch

    Abstract:

    In this paper, a novel approach to analyze in situ (-)-Bornyl Acetate (BA) in pichtae essential oil (Siberian fir needle oil, Abies sibirica oil) by means of Raman optical activity (ROA) is reported. As part of this approach, a conformational study in the gas phase of (+)- and (-)-BA has been carried out, predicting the presence of three conformers for each enantiomer at 298.15 K. The structures of these conformers were optimized with density functional theory with the Becke 3LYP functional and 6-311 + + g* basis set. Subsequently, the Raman and ROA spectra were simulated in order to compare them with the experimentally measured spectra of the neat enantiomers of BA. Finally, the combination of Raman and ROA spectroscopy as well as DFT calculations was successfully applied not only for the detection of BA but also for the determination of the specific enantiomer of BA present in the investigated pichtae essential oil samples. Thus, the ROA technique described here has the potential to be used as a fast and easy commercial method to control the quality of essential oils.
