The major in vivo metabolites of S-(+)- and R-(-)-carvone in a metabolism of ingestion correlated amounts (MICA) experiment were newly identified as alpha,4-dimethyl-5-oxo-3-cyclohexene-1-acetic acid (dihydrocarvonic acid), alpha-methylene-4-methyl-5-oxo-3-cyclohexene-1-acetic acid (carvonic acid), and 5-(1,2-dihydroxy-1-methylethyl)-2-methyl-2-cyclohexen-1-one (uroterpenolone) on the basis of mass
摄入相关量代谢试验(MICA)中S-(+)-和R-(-)-香芹酮的主要体内代谢物新近被鉴定为α,4-二甲基-5-氧代-3-氧代-3-环己烯-1 -乙酸(二氢香芹酸),α-亚甲基-4-甲基-5-氧代-3-环己烯-1-乙酸(香芹酸)和5-(1,2-二羟基-1-甲基乙基)-2-质谱分析结合合成和NMR实验的基础上,对甲基-2-环己烯-1-酮(尿萜烯酮)进行了分析。少量代谢物被鉴定为香芹酮的还原产物,即醇香芹酚和二氢香芹酚。无法检测到兔子先前确定的主要体内代谢产物10-羟基香芹酮,表明浓度影响或种间差异。讨论了人类中香芹酮的代谢途径,包括侧链中双键的氧化以及小范围的1,2-和1,4 + 1,2-还原。没有检测到S-(+)-和R-(-)-香芹酮之间的代谢差异。
