F 17 metabolites had been identified. The significant metabolic pathways on the detected metabolites have been glucuronidation, sulfation, methylation, demethylation, and reduction. These pathways can be traced for the two phases of metabolism, phase I and phase II. Phase I metabolism generally converts a parent drug to far more polar (water soluble) active metabolites by unmasking or inserting a polar functionalScientific RepoRts | five:12961 | DOi: 10.1038/srepDiscussionwww.nature.com/scientificreports/ESI mode – – – – – – – – – – – – – – – – – – – – – – – – – – – – – + + + + + + + + + + + + + + + Abund.
