Abstract Macerates of fruits and leaves of Pistacia lentiscus L. were prepared and analysed with the aim of applying them for active packaging. The profile of forty-four different bioactive volatile compounds was obtained by means of gas chromatography-mass spectrometry and solid-phase microextraction gas chromatography-mass spectrometry. Antioxidant capacity was evaluated by three different methods (2,2-diphenyl-1-picrylhydrazyl, 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid and reducing power) which confirmed stronger antioxidant properties in case of leaves macerate. Total phenolic and flavonoids content was determined and showed that macerate leaves presented 15 times more phenolic compounds and 20 times more flavonoids than macerate fruit. Moreover, the analysis of antimicrobial properties of macerate leaves in comparison with macerate fruits revealed very strong antimicrobial properties. Finally, macerate leaves extract was incorporated in an adhesive and a new active multilayer packaging was designed, and its antioxidant capacity as free radical scavenger was confirmed by a method based on in situ hydroxyl radicals generator.

来自黄连木提取物不同部位的生物活性挥发性化合物及其抗氧化和抗菌活性的研究，用于新型活性包装应用。

摘要 制备并分析了黄连木果实和叶子的浸渍液，以将其用于活性包装。采用气相色谱-质谱法和固相微萃取气相色谱-质谱法，获得了44种不同生物活性挥发性化合物的分布图。通过三种不同的方法（2,2-二苯基-1-苦基肼、2,2'-叠氮基-双（3-乙基苯并噻唑啉-6-磺酸和还原能力）评估抗氧化能力，证实叶子浸渍时具有更强的抗氧化性能. 总酚和类黄酮含量的测定表明，浸渍叶比浸渍果实多 15 倍的酚类化合物和 20 倍的黄酮类化合物。此外，与浸渍果实相比，浸渍叶的抗菌特性分析显示出非常强的抗菌特性。最后，将浸渍叶提取物掺入粘合剂中，设计了一种新型活性多层包装，并通过基于原位羟基自由基发生器的方法证实了其作为自由基清除剂的抗氧化能力。
