Abstract

Food spoilage is a widely neglected problem and the constant use of synthetic fungicides could develop resistant fungi. The objective of this study was to evaluate the chemical composition and antimicrobial activity of Tetradenia riparia leaf essential oil against foodborne disease microorganisms. Leaf essential oil was obtained by hydrodistillation and identified by gas chromatography coupled to mass spectrometry. The antimicrobial activity was studied by broth microdilution. The major compounds identified were oxygenated sesquiterpenes (43.6%): 14-hydroxy-9-epi-(E)-cariophylene (20.8%) and τ-cadinol (18.4%); followed by oxygenated diterpenes (24.6%): 6,7-dehydroroyleanone (12.6%) and 9β, 13β-epoxy-7-abiethene (10.6%); sesquiterpenic hydrocarbons (17.1%) and oxygenated monoterpenes (7.4%): fenchone (5.6%). The essential oil had broad antibacterial and antifungal activity, mainly against A. versicolor and P. ochrochloron with fungistatic and fungicidal activities and B. cereus, L. monocytogenes, and S. aureus with bacteriostatic and bactericidal activities. T. riparia leaf essential oil is a potential alternative to control microorganisms.

河豚叶精油的抗菌活性研究

食品腐败是一个被广泛忽视的问题，持续使用合成杀菌剂可能会产生耐药真菌。本研究的目的是评价河豚叶精油对食源性疾病微生物的化学成分和抑菌活性。采用水蒸气蒸馏法提取叶精油，气相色谱-质谱联用技术对叶精油进行鉴定。采用肉汤微量稀释法研究其抑菌活性。鉴定的主要化合物为含氧倍半萜(43.6%):14-羟基-9-epi-(E)-cariophylene(20.8%)和τ-cadinol (18.4%);其次是含氧二萜(24.6%):6,7-脱氢己烯酮(12.6%)和9β， 13β-环氧-7-亚乙烯(10.6%);倍半萜烯烃(17.1%)和氧合单萜烯(7.4%):茴香(5.6%)。该精油具有广泛的抑菌和抑菌活性，主要对具有抑菌和杀菌活性的花青草芽孢杆菌和异色芽孢杆菌具有抑菌和杀菌活性，对蜡样芽孢杆菌、单核增生乳杆菌和金黄色葡萄球菌具有抑菌和杀菌活性。河岸草叶精油是一种潜在的防治微生物的替代品。

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.
