Figure 2.

Pilot biotransformation of selected silymarin components (200 mg/L) by human fecal microbiota after pre-incubation in simulated gastric and low intestinal conditions. The results are shown as the area under the curve (AUC) of the respective peak in LC/MS chromatograms (logarithmic scale) as a function of time of incubation; minor metabolites with AUC < 1% were excluded for better clarity.
