ABSTRACT
Menthae Haplocalycis Herba has been utilized for food and medicinal purposes in China for thousands of years. It has various efficacies, including dispelling wind and heat and relieving sore throat. M. Haplocalycis Herba has been also widely used in food, cosmetics, spices, and other fields. Exploring the constituents and detecting the metabolites of M. Haplocalycis are of great significance to clarify the effective substances. However, the in vivo metabolites of M. Haplocalycis Herba water extract are still unclear. Herein, a sensitive and specific method, ultra-high performance liquid chromatography with linear ion trap-Orbitrap mass spectrometry, established in this assay was used to study the metabolism of M. Haplocalycis Herba water extract in rat plasma, urine, and feces. We characterized and identified 9, 50, and 34 metabolites in plasma, urine, and feces, respectively. Seven metabolic pathways, including phase â
(isomerization, demethylation, hydroxylation, and dehydration) and phase â
¡ (sulfation and glucuronidation) were mainly involved in the metabolism. It is the first systematic study on the metabolism of M. Haplocalycis Herba water extract in vivo, which enrich current understanding of the metabolic behavior of M. Haplocalycis Herba water extract and provide a metabolic rationale for further in-depth in vivo biotransformation and pharmacokinetic analysis.
