| 論文備考 | ※Preparation of an intestinal bacterial mixture Fresh feces obtained from a healthy subject were thoroughly suspended in 100-fold of 50 mM K-phosphate buffer (pH 7.3) to give a human fecal suspension, which was use in this experiment. [Li et al., Chem. Pharm. Bull., 48, 1239-1241 (2000)] ※Time course of the transformation of precatorin II Precatorin II (3, 10 mmol in 200 ml of DMSO) was added to a human fecal suspension (5%, 3.8 ml) and incubated at 37°C in an anaerobic incubator. Samples were picked up at intervals and treated as mentioned above. Metabolites were quantitatively determined by HPLC. [Li et al., Chem. Pharm. Bull., 48, 1239-1241 (2000)] |
