以 silica gel GF 薄层色谱和放射性碳((14)C)测定法分析了给予 (14)C-二苯甲烷的成年雄性大鼠的尿液、粪便以及两小时胆汁样本中的苯基甲醇以及 2-和 4-羟基二苯甲烷。在 24 小时的尿液中存在 48.4% 的给药量,而在粪便中存在 17.7%。尿液中的 (14)C 隔离物中,苯基甲醇、2-羟基二苯甲烷和 4-羟基二苯甲烷分别占 3.7%、0.3% 和 4.8%,而在粪便中分别占 3.1%、0.8% 和 4.8%。两小时的胆汁样本含有 3.2% 的给药放射性。经过 β-葡萄糖醛酸酶/芳香硫酸酯酶处理后,回收的胆汁放射性中有 71.9% 被鉴定为苯基甲醇(37.5%)和 4-羟基二苯甲烷(34.4%)。
Urine and feces, and two-hour bile samples from adult male rats dosed with (14)C-diphenylmethane were analyzed for benzhydrol and 2- and 4-hydroxydiphenyl-methane by silica gel GF t.l.c. and (14)C-determination. Mean values of 48.4% and 17.7% of the administered (14)C were present in 24 hr urine and feces, respectively. Benzhydrol and 2- and 4-hydroxydiphenylmethane comprised 3.7%, 0.3% and 4.8% respectively of the (14)C isolated from urine and 3.1%, 0.8%, and 4.8% respectively of the (14)C isolated from feces. Bile samples (2 hr) contained 3.2% of the administered radioactivity. After treatment with beta-glucuronidase/aryl sulphatase, 71.9% of the recovered biliary radioactivity was identified as benzhydrol (37.5%) and 4-hydroxydiphenylmethane (34.4%).
