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 free 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 accessible to all readers and 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

25

Blackcurrant (Ribes nigrum L) is a rich source of anthocyanins, however the relationship

26

between their apparently limited bioavailability and significant protection against metabolic

27

pathologies is poorly understood. In this study, we examined gastrointestinal distribution of

28

blackcurrant anthocyanins and their phenolic acid metabolites in lean and diet-induced obese

29

mice with healthy and antibiotic-disrupted microbiome. Daily consumption of low or high fat

30

diet supplemented with 1% blackcurrant powdered extract (32% anthocyanins) for 8 weeks

31

reduced body weight gain and improved glucose metabolism only in mice with the intact gut

32

microbiome. Administration of antibiotic cocktail resulted in the 16-25 fold increase (P
