Echinacoside (ECH) is one of the representative phenylethanoid glycosides. It is widely present in plants and exhibits various bioactivities. However, the extremely low oral bioavailability of ECH in rats implies that ECH may go through multiple hydrolysis steps in the gastrointestinal tract prior to its absorption into the blood. Therefore, the gastrointestinal metabolites of ECH are more likely to be the bioactive components. This study established an approach combining ultraperformance…

A metabolic way to investigate related hurdles causing poor bioavailability in oral delivery of isoacteoside in rats employing ultrahigh-performance liquid chromatography/quadrupole time-of-flight tandem mass spectrometry.
TLDR
The present work has demonstrated that the factors causing the poor bioavailability of isoacteoside should be attributed to the metabolism, and suggested that metabolites might be responsible for the excellent pharmacological effect of ISAT.

TLDR
Investigating the intestinal permeability of a PhG-rich extract from CD as an integrated system in the Caco-2 cell monolayer model using a bioassay system showed that PRE is primarily transported via poorly absorbed passive diffusion down a concentration gradient without efflux, which provides the pharmacokinetic basis for the clinical application of PhGs in CD.

TLDR
These findings indicate that orally administered glycyrrhizin is poorly absorbed from the gut, but is hydrolysed to 18β‐glycyrrhetic acid by intestinal bacteria such as E. sp.
