Background:

Rhein-8-glucoside is an anthraquinone glycoside that has been found in rhubarb.1 It increases the rate of sennoside A metabolism by mouse intestinal bacteria in vitro when used at concentrations ranging from 0.03 to 1 mM. Rhein-8-glucoside increases the purgative activity of sennoside A in mice in a dose-dependent manner. It also inhibits human protein tyrosine phosphatase (PTP1B; IC50 = 11.5 μM).2 Rhein-8-glucoside is metabolized to rhein by intestinal bacteria.1
