Just Accepted “Just Accepted” manuscripts have been peer-reviewed and accepted for publication. They are posted online prior to technical editing, formatting for publication and author proofing. The American Chemical Society provides “Just Accepted” as a service to the research community to expedite the dissemination of scientific material as soon as possible after acceptance. “Just Accepted” manuscripts appear in full in PDF format accompanied by an HTML abstract. “Just Accepted” manuscripts have been fully peer reviewed, but should not be considered the official version of record. They are citable by the Digital Object Identifier (DOI®). “Just Accepted” is an optional service offered to authors. Therefore, the “Just Accepted” Web site may not include all articles that will be published in the journal. After a manuscript is technically edited and formatted, it will be removed from the “Just Accepted” Web site and published as an ASAP article. Note that technical editing may introduce minor changes to the manuscript text and/or graphics which could affect content, and all legal disclaimers and ethical guidelines that apply to the journal pertain.

ABSTRACT

27

This study assessed sixteen different honey samples in order to select the better

28

one for therapeutic purposes. First, a study of honeys´ main bioactive compounds was

29

carried out. Then phenolic profiles were determined and specific compounds quantified

30

using a HPLC system coupled to a mass spectrometer. Then, antioxidant activity, by

31

three in vitro methods, and antibacterial activity against reference strains and clinical

32

isolates were evaluated. Great variability among samples was observed regarding

33

ascorbic acid (between 0.34 ± 0.00 and 75.8 ± 0.41 mg/100 g honey; p
