Abstract

ABSTRACT The present study investigated the antibacterial, antifungal and allelopathic activities of Pistacia lentiscus essential oils (EOs) isolated at the vegetative, flowering and fructification stages. The chemical composition of EOs varied according to both the phenological stages and the used mix plant parts. The main chemical class was sesquiterpene hydrocarbons with the predominance of germacrene D, δ-cadinene and β-caryophyllene. The antibacterial activity was evaluated against five collection strains. At the vegetative stage, P. lentiscus EO was the most effective against Listeria monocytogenes and Echerchia coli as compared to the other stages. P. lentiscus EO also exhibited significant antifungal activity against the phytopathogenic strain Botrytis cinerea. Microscopic observation showed that EO induced swelling and crumbling of B. cinerea conidia. Moreover, P. lentiscus EO at the vegetative stage possessed significant allelopathic activity by inhibiting low concentration the germination and radical elongation of Raphanus sativus and radical elongation of Lepidium sativum.

从黄连木中提取倍半萜作为潜在的抗菌、抗真菌和化感剂

摘要本研究研究了黄连木(Pistacia lentiscus)在营养、开花和结果期的抑菌、抗真菌和化感作用。不同的物候阶段和混合植物的不同部位，其化学成分也不同。其主要化学类为倍半萜烃，主要为γ -癸烯D、δ-癸烯和β-石竹烯。对5株收集菌株进行抑菌活性评价。在营养阶段，与其他阶段相比，P. lentiscus EO对单核增生李斯特菌和大肠埃希菌的抑制效果最好。P. lentiscus EO对植物病原菌灰霉病菌(Botrytis cinerea)也有显著的抗真菌活性。显微镜下观察发现，EO可引起葡萄球菌分生孢子的肿胀和破碎。营养期扁豆提取物具有明显的化感作用，可以抑制低浓度莴苣的萌发和根伸长，也可以抑制小黄草的根伸长。

期刊介绍： Journal of Essential Oil Research ( JEOR) is the major forum for the publication of essential oil research and analysis. Each issue includes studies performed on the chemical composition of some of the 20,000 aromatic plants known in the plant kingdom. JEOR is devoted entirely to all phases of research from every corner of the world by the experts in their field. JEOR''s main areas of focus include: -Analytical chemistry- Biological activity- Biotechnology- Chemical composition- Chemical synthesis- Chemosystematics- Microbiological activity- Plant biochemistry/biosynthesis- Toxicology. Published six times per year, JEOR provides articles on the aromatic principles of a plant or its isolates and are directed toward furthering our readers'' knowledge of the aromatic plant and animal kingdoms.
