Abstract

The aim of this study was to undertake a screening experiment on essential oils (EO) of Myrcia lundiana, Ocimum basilicum and Lippia alba against six food-spoiling pathogenic bacteria. Seventy-two (72) samples were initially analyzed for antimicrobial activity based on the agar diffusion test. The minimum inhibitory (MIC) and bactericidal (MBC) concentrations were determined for the 12 samples which showed greatest antimicrobial potential in this stage. Two samples of L. alba, three samples of M. lundiana and seven samples of O. basilicum showed a MIC of 0.12-125 μL/mL for the six tested bacteria. Of these, the EO of O. basilicum cultivar Maria Bonita stood out with the lowest MIC and MBC. Thus, a mixture simulating this essential oil was prepared from commercial standards of the compounds (±)-linalool, geraniol and 1,8-cineole. Significantly higher MIC and MBC were detected in the simulation compared to the respective EO, suggesting a synergistic effectbetween compounds.

白皮、桃金娘和罗勒精油对6种食品腐败病原微生物的抑菌活性

本研究的目的是对桃金娘、罗勒木和白梨精油进行抗6种食品腐败致病菌的筛选实验。根据琼脂扩散试验初步分析了72份样品的抗菌活性。测定了这一阶段具有最大抑菌潜力的12份样品的最低抑菌浓度(MIC)和杀菌浓度(MBC)。2份白乳杆菌、3份伦黛娜乳杆菌和7份basilicum乳杆菌的MIC值为0.12 ~ 125 μL/mL。其中，大葱品种的EO以最低的MIC和MBC表现突出。因此，从商业标准化合物(±)-芳樟醇，香叶醇和1,8-桉树脑制备了模拟该精油的混合物。与各自的EO相比，模拟中检测到明显更高的MIC和MBC，表明化合物之间存在协同效应。

期刊介绍： The Boletín Latinoamericano y del Caribe de Plantas Medicinales y Aromáticas (BLACPMA), [Latin American and Caribbean Bulletin of Medicinal and Aromatic Plants]; currently edited by the publishing house MS-Editions, is a bi-monthly international publication that publishes original peerreviewed research in the field of medicinal and aromatic plants, with nearly 20 years of experience. BLACPMA is a scientific journal that publishes two types of articles: Reviews (only in English) and Original Articles (Spanish or English), its main lines of action being agronomy, anthropology and ethnobotany, industrial applications, botany, quality and standardization, ecology and biodiversity, pharmacology, phytochemistry, pharmacognosy, regulatory and legislative aspects. While all areas of medicinal plants are welcome and the experimental approaches used can be broad and interdisciplinary; other areas of research that are not mentioned depend on the Editorial Committee for their acceptance.
