The present paper reports the GC-HS-SPME analysis of volatile emission and GC-MS analysis of chemical composition of essential oil of fruits of eight different samples of L. fruits ("sumac" folk name), collected from Jordanian agricultural field and the local market. The analyses show an important variability among the Sumac samples probably due to the origin, cultivation, harvesting period, drying, and conservation of the plant material. The main class of component present in all samples was monoterpenes (43.1 to 72.9%), except for one sample which evidenced a high percentage of sesquiterpene hydrocarbons (38.5%). The oxygenated monoterpenes provided a contribution to total class of monoterpenes ranging from 10.1 to 24.3%. A few samples were rich in monoterpene hydrocarbons. Regarding the single components present in all the volatile emissions, β-caryophyllene was the main compound in most of the analyzed samples, varying from 34.6% to 7.9%. Only two samples were characterized by α-pinene as the main constituent (42.2 and 40.8% respectively). Essential oils were collected using hydro-distillation method. Furfural was the main constituent in almost all the analyzed EOs (4.9 to 48.1%), except in one of them, where β-caryophyllene was the most abundant one. β-caryophyllene ranged from 1.2 to 10.6%. Oxygenated monoterpenes like carvone and carvacrol ranged from 3.2-9.1% and 1.0-7.7% respectively. Cembrene was present in good amount in EO samples EO-2 to EO-8. The antioxidant capacities of the fruit essential oils from were assessed using spectrophotometry to measure free radical scavenger 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical and inhibition of β-carotene bleaching (BCB). The essential oils from the fruits of the different samples of exhibited the MIC value ranging from 32.8 to 131.25 µg/mL against and 131.25 to 262.5 µg/mL against . The MIC values of ciprofloxacin were 0.59 and 2.34 µg/mL against and , respectively.
本研究采用 GC-HS-SPME 分析了 8 种不同约旦农田和当地市场采集的 果实的挥发物，并用 GC-MS 分析了其精油的化学成分。分析表明，由于植物材料的来源、种植、收获期、干燥和保存等因素，“sumac”（漆树）样本之间存在重要的变异性。所有样本中的主要成分类别均为单萜（43.1%至 72.9%），除了一个样本，其中萜烯碳氢化合物的含量较高（38.5%）。含氧单萜对总单萜类化合物的贡献在 10.1%至 24.3%之间。一些样本富含单萜碳氢化合物。至于所有挥发性排放物中存在的单一成分，β-石竹烯是大多数分析样本中的主要化合物，含量在 34.6%至 7.9%之间。只有两个样本以α-蒎烯为主要成分（分别为 42.2%和 40.8%）。精油采用水蒸馏法收集。糠醛是几乎所有分析精油（4.9%至 48.1%）的主要成分，除了其中一种，其中β-石竹烯含量最高。β-石竹烯的含量在 1.2%至 10.6%之间。单萜类含氧化合物如香芹酮和香芹酚的含量分别为 3.2-9.1%和 1.0-7.7%。石竹烯在 EO-2 至 EO-8 号精油样品中含量丰富。采用分光光度法评估果实精油的抗氧化能力，以测量自由基清除剂 2,2-二苯基-1-苦基肼（DPPH）自由基和β-胡萝卜素漂白（BCB）抑制率。不同 样本的果实精油对 和 的最低抑菌浓度（MIC）值范围分别为 32.8 至 131.25 µg/mL 和 131.25 至 262.5 µg/mL。环丙沙星对 和 的 MIC 值分别为 0.59 和 2.34 µg/mL。
