摘要

本研究考察了连续三个生长季节天气条件（降水和温度）对苦艾精油和水化回收油挥发性有机化合物分布的影响。在开花期间收获植物材料，并进行蒸汽蒸馏以获得精油，同时使用Likens-Nickerson方法从水合物中提取回收油。采用气相色谱-质谱联用（GC-MS）和火焰电离检测法（FID）分析了挥发性有机化合物的组成和浓度。反式图琼酮和乙酸反式杉木酯是精油和加氢油中主要的化合物。时间常数揭示了整个研究期间挥发性有机化合物分布的动态变化。感官分析显示，精油和水合物的气味几乎相同，主要是一种强烈的特有气味。本研究对天气条件对苦艾精油和水合提取油的化学成分的影响提供了有价值的见解。苦艾草的回收油和相应的精油具有相同的化学和感官特征，这表明该水合物在既需要精油又需要水相的产品中具有工业应用的潜力。这表明，苦艾草水合酸盐有潜力从废物发展成为多种行业的增值产品，如农业、化妆品和食品生产。

Correlation between weather conditions and volatile organic compound profiles in Artemisia absinthium L. essential oil and recovery oil from hydrolate

This study investigated the influence of weather conditions (precipitation and temperature) on volatile organic compound profiles of Artemisia absinthium essential oil and recovery oil from hydrolate over three consecutive growing seasons. Plant material was harvested during flowering and subjected to steam-distillation to obtain essential oil, while recovery oil from hydrolate was extracted using the Likens-Nickerson method. Gas chromatography-mass spectrometry (GC-MS) and flame ionization detection (FID) were employed to analyze the volatile organic compound composition and their concentrations. Trans-thujone and trans-sabinyl acetate were identified as the dominant compounds in both essential oil and recovery oil from hydrolate. Time constants revealed dynamic changes in volatile organic compound profiles throughout the study period. Sensory analysis revealed an almost identical odor profiles for the essential oil and hydrolate, dominated by a characteristic strong thujonic scent. This research provides valuable insights into the impact of weather conditions on the chemical composition of A. absinthium essential oil and recovery oil from hydrolate. The identical chemical and sensory profiles of the recovery oil and corresponding essential oil from A. absinthium indicate the potential for industrial application of the hydrolate in products that require both an essential oil and an aqueous phase. This suggests that A. absinthium hydrolate has the potential to evolve from waste products into a value-added product in various industries, such as agriculture, as well as cosmetic and food production.

期刊介绍： Biochemical Systematics and Ecology is devoted to the publication of original papers and reviews, both submitted and invited, in two subject areas: I) the application of biochemistry to problems relating to systematic biology of organisms (biochemical systematics); II) the role of biochemistry in interactions between organisms or between an organism and its environment (biochemical ecology). In the Biochemical Systematics subject area, comparative studies of the distribution of (secondary) metabolites within a wider taxon (e.g. genus or family) are welcome. Comparative studies, encompassing multiple accessions of each of the taxa within their distribution are particularly encouraged. Welcome are also studies combining classical chemosystematic studies (such as comparative HPLC-MS or GC-MS investigations) with (macro-) molecular phylogenetic studies. Studies that involve the comparative use of compounds to help differentiate among species such as adulterants or substitutes that illustrate the applied use of chemosystematics are welcome. In contrast, studies solely employing macromolecular phylogenetic techniques (gene sequences, RAPD studies etc.) will be considered out of scope. Discouraged are manuscripts that report known or new compounds from a single source taxon without addressing a systematic hypothesis. Also considered out of scope are studies using outdated and hard to reproduce macromolecular techniques such as RAPDs in combination with standard chemosystematic techniques such as GC-FID and GC-MS.
