The Relative Content and Distribution of Absorbed Volatile Organic Compounds in Rats Administered Asari Radix et Rhizoma Are Different between Powder- and Decoction-Treated Groups

ABSTRACT: Asari Radix et Rhizoma (ARR) is an important traditional Chinese medicine. Volatile organic compounds (VOCs) are the main active constituents of ARR. Research on the metabolite profile of VOCs and the difference of absorbed constituents in vivo after an administration of ARR decoction and powder will be helpful to understand the pharmacological activity and safety of ARR. In this study, headspace solid-phase microextraction gas chromatography mass spectrometry (HS-SPME-GC-MS) was applied to profile the VOCs from ARR in rats in vivo. A total of 153 VOCs were tentatively identified; 101 were original constituents of ARR (98 in the powder-treated group and 43 in the decoction-treated group) and 15 were metabolites, and their metabolic reactions were mainly oxidation and reduction, with only two cases of methylation and esterification, and 37 unclassified compounds were identified only in the ARR-treated group. Of the 153 VOCs identified, 131 were reported in rats after oral administration of ARR for the first time, containing 79 original constituents, 15 metabolites, and 37 unclassified compounds. In the powder-treated group, methyleugenol, safrole, 3,5-dimethoxytoluene (3,5-DMT), 2,3,5-trimethoxytoluene (2,3,5-TMT), and 3,4,5-trimethoxytoluene (3,4,5-TMT) were the main absorbed constituents, the relative contents of which were significantly higher compared to the decoction-treated group, especially methyleugenol, safrole, and 3,5-DMT. In the decoction-treated group, 3,4,5-TMT, 2,3,5-TMT, kakuol, and eugenol were the main constituents with a higher content and wider distribution. The results of this study provide a reference for evaluating the efficacy and safety of ARR.

Project description:BACKGROUND: Diarrhea is common in infants, particularly, children less than 2 years old. Intractable or protracted infancy diarrhea is typically associated with feeding intolerance and malabsorption that is lethal for newborns. This study aimed to evaluate the effectiveness of baizhu shaoyao decoction in reducing functional diarrhea induced by weaning stress, while also delving into its potential mechanisms of action.RESULTS: Piglets were allocated into 5 groups, with each group receiving designated medication for a continuous 14-day period: control, zaohu powder, as well as low-, medium- and high-dose baizhu shaoyao decoction groups (n = 6 piglets per group). To identify diarrhea-related biomarkers, microbial communities, functions and metabolites were compared between the early-weaned piglets (control group) and those treated with 1.28 g/kg baizhu shaoyao decoction (medium-dose baizhu shaoyao decoction group). Our findings revealed significant shifts in microbial composition, function and metabolic profiles in piglets from the medium-dose baizhu shaoyao decoction group, intricately associated with the host's diarrhea status. Furthermore, carbohydrate metabolism and biosynthesis, lipid and amino acid metabolism, glycan activity and carbohydrate digestive enzymes exhibited downregulation in piglets of the medium-dose baizhu shaoyao decoction group compared to those in the control group. Transcriptome analysis highlighted the pivotal role of the FoxO1/3 transcription factor in mitigating weaning stress, particularly through the augmentation of CD4+/CD8+ T cell proportions. Our findings underscored that baizhu shaoyao decoction's therapeutic effects on weaning stress involve intestinal barrier restoration, modulation of brain-gut peptide expression and a reduction in mast-cell activity in the ileum.CONCLUSIONS: The key metabolites (chenodeoxycholyglycine, chenodeoxycholyltaurine, dinoprost, chenodeoxyglycocholic acid, glycochenodeoxycholic acid, glycocholic acid, N-choloylglycine, 5-trans-PGE2, Pregnanediol 3-O-glucuronide, spermidine and spermine) exhibited strong correlations with the abundance of Clostridia_bacterium and Lachnospiraceae_bacterium, emphasizing the significance of Clostridia_bacterium and Lachnospiraceae_bacterium in gut metabolism and function. Besides, this study suggests the potential efficacy of baizhu shaoyao decoction in addressing early post-weaning stress-induced diarrhea in infants, showcasing promising prospects for translational and clinical applications.
