Baobab: from Saint-Exupéry to LS9 labs.

There is a baobab tree that constantly tries to grow and overrun the surface of Little Prince’s planet, in the famous Saint Exupéry novel. The french author may have not been aware of that, but Adansonia digitata L. (African baobab), is not so easy to grow and cultivate, and in particular its growth is not properly quick. However, in our common planet, Baobab is nowadays an important multi-purpose tree, whose distribution is at present limited to wild or semi-domesticated individuals widespread in Africa. Its distribution is threatened by seedling clearance for other land use and...

… and one more orange juice, please!

This time we assessed the bioavailability of orange juice (poly)phenols by monitoring urinary flavanone metabolites and ring fission catabolites produced by the action of the colonic microbiota. Our objective was to identify and quantify metabolites and catabolites excreted in urine 0–24 h after the acute ingestion of a (poly)phenol-rich orange juice by 12 volunteers.Results showed that a total of 14 metabolites were identified and quantified in urine by using HPLC-MS after orange juice intake. Hesperetin-O-glucuronides, naringenin-O-glucuronides, and hesperetin-3′-O-sulfate were the main...

What’s in season? Oranges!

The core business of our Nutrition branch is represented by human colonic metabolism and bioavailability of polyphenols. This time, the focus was on the in vitro colonic catabolism of orange juice (poly)phenols and in particular we investigated the role of colonic microbiota in the breakdown of hesperetin, naringenin, and ferulic acid, compounds found as glycosides in orange juice. Test compounds were incubated with human faecal slurries cultured under anaerobic conditions, and the production of phenolic acid catabolites were monitored by GC-MS and HPLC-MS2. Hesperetin was converted to...

Inside food supplements: phytochemistry of a fruit blend

There is continuously accruing evidence to suggest the health benefits of consuming fruits and vegetables. Food supplements may represent an effective and acceptable method to deliver a way of providing bioactive compounds to consumers. At the same time, food supplements are often a mixture of different plant extracts, giving raise to a complex combination of different plant secondary metabolites that may be difficult to monitor properly.  The aim our latest paper was to characterize the (poly)phenolic composition of three plant-based food supplements designed to integrate and increase the...

Front cover!

You can’t judge a book by its cover. And neither a review in a peer-reviewed journal, we dare say. But we love the fancy cover of the latest issue of Food & Function, because it was drawn by Pedro Mena and Margherita Dall’Asta of the LS9 crew, to celebrate our review recently published....
