Daikenchuto (TU-100) shapes gut microbiota architecture and increases the production of ginsenoside metabolite compound K.

ABSTRACT: Many pharmaceutical agents not only require microbial metabolism for increased bioavailability and bioactivity, but also have direct effects on gut microbial assemblage and function. We examined the possibility that these actions are not mutually exclusive and may be mutually reinforcing in ways that enhance long-term of these agents. Daikenchuto, TU-100, is a traditional Japanese medicine containing ginseng. Conversion of the ginsenoside Rb1 (Rb1) to bioactive compound K (CK) requires bacterial metabolism. Diet-incorporated TU-100 was administered to mice over a period of several weeks. T-RFLP and 454 pyrosequencing were performed to analyze the time-dependent effects on fecal microbial membership. Fecal microbial capacity to metabolize Rb1 to CK was measured by adding TU-100 or ginseng t
