To study the metabolites of glycyrrhetic acid (GA) in rat bile, an analytical method was developed to identify GA and its metabolites by liquid chromatography mass spectrometry (LC-MS). Rat bile was collected after i.v. injection of GA. Three major GA-related peaks were detectable in rat bile by high-performance liquid chromatography (HPLC) analysis at 254 nm. LC-MS spectra showed their protona...

To evaluate the pharmacological actions of herbal medicines, metabolic activities of herbal medicine components, ginsenoside Rb1, glycyrrhizin, geniposide and baicalin to their bioactive compounds compound K, 18beta-glycyrrhetic acid, genipin and baicalein by fecal specimens were measured. Their metabolic activities were 646.1+/-591.4, 29.4+/-51.7, 926.3+/-569.6 and 3884.6+/-1400.1 micromol/h/g...

We have investigated the effect of glycyrrhetic acid (GR) which is metabolic substance of glycyrrhizin, on DNA of human hepatoma (HLE), promyelotic leukemia (HL-60) and stomach cancer (KATO III) cells. GR displayed apoptotic effects against HLE, HL-60 and KATO III cells. The fragmentation of DNA by GR to oligonucleosomal-sized fragments, a characteristic of apoptosis, was doseand timedependent ...
