Journal of pharmaceutical and biomedical analysis, 174, 19-33 (2019-06-04)

Africa is famous for its floral biodiversity, exploited by local people for therapeutic purposes. However, such plants need to be scrutinised scientifically for the presence of bioactive compounds and possible biological properties. This study attempts for the first time to

A comparison of the in vitro biotransformation of (-)-epicatechin and procyanidin B2 by human faecal microbiota.

Stavroula Stoupi et al.

Molecular nutrition & food research, 54(6), 747-759 (2009-11-28)

The catabolism by human faecal microbiota of (-)-epicatechin (1) (2, 3-cis stereochemistry) and its dimer pure procyanidin B2 (2), has been compared using a static in vitro culture model. The catabolites were characterised by LC-MS(n), UV absorption and relative retention
