摘要

本研究旨在评价三种桉树(botryoides, E. cladocalyx, E. grandis)精油的化学品质、抗氧化活性和抑菌活性。化学成分鉴定表明，1,8-桉叶油脑、α-蒎烯和β-(Z)-桉叶油脑是这些精油的主要成分。在160 mg/mL浓度下，对DPPH自由基的清除率为80.83%，对DPPH自由基的清除率为80.46%，经FRAP试验证实。在抑菌活性方面，精油对所有菌株的生长均有显著抑制作用。当最小抑菌浓度为1/2000 v/v时，叶萼青霉对真菌的抑菌效果较好，而当最小抑菌浓度为1/1000 v/v时，大叶萼青霉对细菌和真菌的抑菌效果较好。最后，botryoides EO对所测试的微生物菌株的效果较差。

Phytochemical analysis, antioxidant and antimicrobial activity of three Eucalyptus species essential oils from the Moroccan Maâmora Forest: Eucalyptus cladocalyx F.Muell, Eucalyptus grandis W.Hill ex Maiden and Eucalyptus botryoides Sm.

This research aimed to evaluate the chemical quality, antioxidant, and antimicrobial (antibacterial and antifungal) activity of essential oils (EOs) from three species of Eucalyptus: E. botryoides, E. cladocalyx, and E. grandis. The identification of the chemical profile of these essential oils revealed that 1,8-cineole, α-pinene, and β-(Z)-ocimene constitutes the significant compounds of these EOs. The antioxidant power tests of the essential oils of E. grandis and and E. cladocalyx shows a strong scavenging activity of the DPPH free radical with a percentage of 80.83 % and 80.46 % respectively at the concentration of 160 mg/mL, results confirmed by the FRAP test. As for the antimicrobial activity, the essential oils significantly inhibited the growth against all the strains studied. E. cladocalyx EOs were preferentially effective against fungi at the minimum inhibitory concentration of 1/2000 v/v, then E. grandis EOs were more effective against bacteria and fungi at the minimum inhibitory concentration of 1/1000 v/v. Finally, E. botryoides EO is less effective against the tested microbial strains.

期刊介绍： Chemical Data Collections (CDC) provides a publication outlet for the increasing need to make research material and data easy to share and re-use. Publication of research data with CDC will allow scientists to: -Make their data easy to find and access -Benefit from the fast publication process -Contribute to proper data citation and attribution -Publish their intermediate and null/negative results -Receive recognition for the work that does not fit traditional article format. The research data will be published as ''data articles'' that support fast and easy submission and quick peer-review processes. Data articles introduced by CDC are short self-contained publications about research materials and data. They must provide the scientific context of the described work and contain the following elements: a title, list of authors (plus affiliations), abstract, keywords, graphical abstract, metadata table, main text and at least three references. The journal welcomes submissions focusing on (but not limited to) the following categories of research output: spectral data, syntheses, crystallographic data, computational simulations, molecular dynamics and models, physicochemical data, etc.
