ABSTRACT The aim of this study was to determine the chemical profile of monoterpenes (including identification of stereoisomers) contained in celery seed essential oil derived from waste celery seeds (Apium graveolens L.), which did not meet commercial quality criteria as a sowing material, and to evaluate the biological activity and sensory profile of the oil. The main constituent of the oil was (R)-(+)-limonene (75.06%). The antimicrobial activity of the oil was assessed using the impedimetric method to find its minimum inhibitory concentration (MIC) against the bacteria (Bacillus subtilis (MIC 50 μL/mL), Staphylococcus aureus (MIC 2 μL/mL), Escherichia coli (MIC 20 μL/mL) and Pseudomonas aeruginosa (MIC 30 μL/mL)) as well as the fungi (Candida vini (MIC 50 μL/mL), Aspergillus niger (MIC 50 μL/mL), and Penicillium expansum (MIC 50 μL/mL)). The oil showed high radical scavenging activity for DPPH (IC50 = 89.11 g/l). Fragrance perception depended on the sex of the panellists.

来自废芹菜种子的精油的生物、化学和香气特征 (Apium Graveolens L.)

摘要 本研究的目的是确定芹菜籽精油中含有的单萜的化学特征（包括立体异构体的鉴定），该精油源自废芹菜种子 (Apium grayolens L.)，作为播种材料不符合商业质量标准，并评估油的生物活性和感官特征。该油的主要成分是 (R)-(+)-柠檬烯 (75.06%)。使用阻抗法评估油的抗菌活性，以确定其对细菌（枯草芽孢杆菌（MIC 50 μL/mL）、金黄色葡萄球菌（MIC 2 μL/mL）、大肠杆菌（MIC 20）的最小抑菌浓度（MIC） μL/mL) 和铜绿假单胞菌 (MIC 30 μL/mL)）以及真菌（葡萄球菌（MIC 50 μL/mL）、黑曲霉（MIC 50 μL/mL）和膨胀青霉（MIC 50 μL/mL） ))。该油对 DPPH 显示出高自由基清除活性 (IC50 = 89.11 g/l)。香味感知取决于小组成员的性别。
