Anal Bioanal Chem 2024; 416:559-568. [PMID: 38040943 PMCID: PMC10761390 DOI: 10.1007/s00216-023-05063-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/25/2023] [Revised: 11/17/2023] [Accepted: 11/20/2023] [Indexed: 12/03/2023]
Abstract
Ion mobility spectrometry-mass spectrometry (IMS-MS) separates gas phase ions due to differences in drift time from which reproducible and analyte-specific collision cross section (CCS) values can be derived. Internally conducted in vitro and in vivo metabolism (biotransformation) studies indicated repetitive shifts in measured CCS values (CCSmeas) between parent drugs and their metabolites. Hence, the purpose of the present article was (i) to investigate if such relative shifts in CCSmeas were biotransformation-specific and (ii) to highlight their potential benefits for biotransformation studies. First, mean CCSmeas values of 165 compounds were determined (up to n = 3) using a travelling wave IMS-MS device with nitrogen as drift gas (TWCCSN2, meas). Further comparison with their predicted values (TWCCSN2, pred, Waters CCSonDemand) resulted in a mean absolute error of 5.1%. Second, a reduced data set (n = 139) was utilized to create compound pairs (n = 86) covering eight common types of phase I and II biotransformations. Constant, discriminative, and almost non-overlapping relative shifts in mean TWCCSN2, meas were obtained for demethylation (- 6.5 ± 2.1 Å2), oxygenation (hydroxylation + 3.8 ± 1.4 Å2, N-oxidation + 3.4 ± 3.3 Å2), acetylation (+ 13.5 ± 1.9 Å2), sulfation (+ 17.9 ± 4.4 Å2), glucuronidation (N-linked: + 41.7 ± 7.5 Å2, O-linked: + 38.1 ± 8.9 Å2), and glutathione conjugation (+ 49.2 ± 13.2 Å2). Consequently, we propose to consider such relative shifts in TWCCSN2, meas (rather than absolute values) as well for metabolite assignment/confirmation complementing the conventional approach to associate changes in mass-to-charge (m/z) values between a parent drug and its metabolite(s). Moreover, the comparison of relative shifts in TWCCSN2, meas significantly simplifies the mapping of metabolites into metabolic pathways as demonstrated.

JOURNAL OF ETHNOPHARMACOLOGY 2023; 317:116815. [PMID: 37400006 DOI: 10.1016/j.jep.2023.116815] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/19/2023] [Revised: 06/07/2023] [Accepted: 06/16/2023] [Indexed: 07/05/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Sophora davidii (Franch.) Skeels Flower (SDF) is a characteristic folk medicine in Yunnan and Guizhou, which can be used to prevent the occurrence of tumors. The extract of SDF (SDFE) is confirmed to be antitumor by pre-experiment. However, effective components and anticancer mechanisms of SDFE are still unclear. AIM OF THE STUDY The purpose of this study was to explore the material basis and action mechanisms of SDFE in the treatment of non-small cell carcinoma (NSCLC). MATERIALS AND METHODS UHPLC-Q-Exactive-Orbitrap-MS/MS was used to identify the chemical components of SDFE. The network pharmacology was applied to screen out the main active components, core genes and related signaling pathways of SDFE in treatment of NSCLC. Molecular docking was used to predict the affinity of major components and core targets. The database was applied to predict the mRNA and protein expression levels of core targets in NSCLC. Finally, the experiments in vitro were performed by CCK-8, flow cytometry and western blot (WB). RESULTS In this study, 98 chemical components were identified by UHPLC-Q-Exactive- Orbitrap-MS/MS. 5 main active components (namely quercetin, genistein, luteolin, kaempferol, isorhamnetin), 10 core genes (namely TP53, AKT1, STAT3, SRC, MAPK3, EGFR, JUN, EP300, TNF, PIK3R1) and 20 pathways were screened out through network pharmacology. The 5 active ingredients were molecularly docked with the core genes, and most the LibDockScore values were higher than 100. The data collected from the database indicated that TP53, AKT1 and PIK3R1 were closely related to the occurrence of NSCLC. The results of experiment in vitro showed that SDFE promoted NSCLC cells apoptosis by down-regulating the phosphorylation of PI3K, AKT and MDM2, up-regulating the phosphorylation of P53, inhibiting the expression of Bcl-2 and up-regulating the expression of Bax. CONCLUSION The combination of network pharmacology, molecular docking, database validation, and in vitro experimental validation effectively demonstrates that SDFE can promote cell apoptosis by regulating PI3K-AKT/MDM2-P53 signaling pathway, so as to treat NSCLC.

Abstract
BACKGROUND Functional constipation is a common gastrointestinal disorder especially severely affecting the life quality of the aged. Jichuanjian (JCJ) has been widely used for aged functional constipation (AFC) in clinic. Yet, the mechanisms of JCJ merely scratch the surface with being studied at a single level, rather than from a systematic perspective of the whole. AIM The purpose of this study was to explore the underlying mechanisms of JCJ in treating AFC from the perspectives of fecal metabolites and related pathways, gut microbiota, key gene targets and functional pathways, as well as "behaviors-microbiota-metabolites" relationships. METHODS 16S rRNA analysis and fecal metabolomics combined with network pharmacology were applied to investigate the abnormal performances of AFC rats, as well as the regulatory effects of JCJ. RESULTS JCJ significantly regulated the abnormalities of rats' behaviors, the microbial richness, and the metabolite profiles that were interrupted by AFC. 19 metabolites were found to be significantly associated with AFC involving in 15 metabolic pathways. Delightfully, JCJ significantly regulated 9 metabolites and 6 metabolic pathways. AFC significantly interrupted the levels of 4 differential bacteria while JCJ significantly regulated the level of SMB53. HSP90AA1 and TP53 were the key genes, and pathways in cancer was the most relevant signaling pathways involving in the mechanisms of JCJ. CONCLUSION The current findings not only reveal that the occurrence of AFC is closely related to gut microbiota mediating amino acid and energy metabolism, but also demonstrate the effects and the underlying mechanisms of JCJ on AFC.

Abstract
BACKGROUND Barberry plants can be considered as useful additives and functional compounds in various industries, especially in the food industry. Berberine (BBR), the most important functional compound in the barberry roots, has recently been used to treat obesity, diabetes, and atherosclerosis. Gut microbiota and the intestinal barrier play an important role in the development of glucolipid metabolism disorders (GLMDs). However, the association of gut microbiota metabolism disorder and the intestinal barrier dysfunction effect of BBR in GLMDs remains elusive. RESULTS The results showed that administration of BBR could increase the number of colonic glands and goblet cell mucus secretion, improve the intestinal barrier function, and reduce the serum glycolipid level in GLMD hamsters. Interestingly, BBR was metabolized into 12 metabolites by gut microbiota, and the main metabolic pathways were oxidation, demethylation, and hydrogenation. In addition, BBR significantly improved the species diversity and uniformity of gut microbiota and promoted the proliferation of beneficial microbiota. Furthermore, the levels of tryptophan metabolites, such as indole, indole-3-acetamide, indole-3-acetaldehyde, indole-3-pyruvic acid, and indole-3-acetic acid were significantly altered by BBR. Both the intestinal tight junction proteins and intestinal immune factors were altered by BBR. CONCLUSION BBR could alleviate intestinal barrier dysfunction of GLMDs by modulating gut microbiota and gut-microbiota-related tryptophan metabolites, which may be one of the pharmacological mechanisms for the treatment of GLMDs. © 2022 Society of Chemical Industry.

Abstract
Galangin, a naturally available flavonoid, induces a variety of pharmacological activities and biological effects via several mechanisms. However, in vivo metabolism of galangin has not been fully explored, which means knowledge of its pharmacodynamics and application potential is limited. The objective of this study was to establish an ultra-high-performance liquid chromatography-quadrupole time-of-flight mass spectrometry method for the rapid profiling and identification of galangin metabolites in vitro and in vivo using unique online information-dependent acquisition with multiple mass defect filtering combined with dynamic background subtraction in positive ion mode. A total of 27 metabolites were detected and characterized, among which eight metabolites in liver microsomes and four metabolites in intestinal microflora were characterized, and 27 metabolites from rat plasma, bile, urine, feces, and a number of different tissue samples were characterized. Thirteen major metabolic pathways including hydrogenation, hydroxylation, glycosylation, methylation, acetylation, glucuronidation, and sulfation were observed to be attributable to the biotransformation of the metabolites. This study provides evidence for the presence of in vitro and in vivo metabolites and the pharmacokinetic mechanism of galangin. Moreover, the study promotes the further development and utilization of galangin and the plant from which it is derived, Alpinia officinarum Hance.

Abstract
Linarin is a natural flavonoid compound found in Chrysanthemum indicum, Mentha species and other plants with various biological activities. The study aimed to investigate the protective effect of linarin supplementation on dextran sulfate sodium (DSS)-induced colitis in C57BL/6J mice and its potential mechanisms. The results showed that doses of linarin at 25 and 50 mg kg-1 day-1 alleviated the DSS-induced histopathological damage, and improved the mucosal layer and intestinal barrier function. Importantly, Linarin significantly suppressed the levels of myeloperoxidase activity and pro-inflammatory cytokines (IL-6, TNF-α, IFN-γ and IL-1β) in the colon, and enhanced the mRNA level of anti-inflammatory cytokine (IL-10). Moreover, 50 mg kg-1 day-1 linarin reversed the gut microbiota damaged by DSS, including Alistipes, Rikenella and Clostridia UCG-014_norank. Linarin also partly increased the relative abundance of short-chain fatty acids (SCFAs)-producing bacteria, including Lactobacillus, Roseburia, Parabacteroides and Blautia, and elevated the contents of SCFAs. Collectively, linarin attenuates DSS-induced colitis in mice, suggesting that linarin may be a promising nutritional strategy for reducing inflammatory bowel disease.

Abstract
Alzheimer's disease (AD) is an age-related neurodegenerative disorder, the incidence of which is climbing with ever-growing aged population, but no cure is hitherto available. The epidemiological studies unveiled that chronic intake of flavonoids was negatively associated with AD risk. Flavonoids, a family of natural polyphenols widely distributed in human daily diets, were readily conjugated by phase II drug metabolizing enzymes after absorption in vivo, and glucuronidation could occur in 1 min following intravenous administration. Recently, as many as 191 metabolites were obtained after intragastric administration of a single flavonoid, indicating that other bioactive metabolites, besides conjugates, might be formed and account for the contradiction between efficacy of flavonoids in human or animal models and low systematic exposure of flavonoid glycosides or aglycones. In this review, metabolism of complete 68 flavonoid monomers potential for AD treatment, grouped in flavonoid O-glycosides, flavonoid aglycones, flavonoid C-glycosides, flavonoid dimers, flavonolignans and prenylated flavonoids according to their common structural elements, respectively, has been systematically retrospected, summarized and discussed, including their unequivocally identified metabolites, metabolic interconversions, metabolic locations, metabolic sites (regio- or stereo-selectivity), primarily involved metabolic enzymes or intestinal bacteria, and interspecies correlations or differences in metabolism, and their bioactive metabolites and the underlying mechanism to reverse AD pathology were also reviewed, providing whole perspective about advances on extensive metabolism of diverse potent flavonoids in vivo and in vitro up to date and aiming at elucidation of mechanism of actions of flavonoids on AD or other central nervous system (CNS) disorders.

Abstract
Oroxin B, a flavonoid, is a major bioactive component form Oroxylum indicum (L.) Vent. with enormous anti-hepatoma effects. To data, the oroxin B metabolism studies remain underexplored. This study was designed to characterize oroxin B metabolism in vivo and in vitro by ultrahigh-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (UHPLC-Q-TOF-MS/MS). Consequently, 30 metabolites in rats, 8 metabolites in liver microsomes and 18 metabolites in intestinal bacteria were identified, and 9 metabolites were recognized by comparison with standards. The biotransformation processes involved ketone, acetylation, loss of C12H20O10, and loss of C6H10O5. And baicalein and oroxin A were generated after loss of C12H20O10, and loss of C6H10O5, respectively, and further went through some other reactions, such as oxidation, methylation, internal hydrolysis, hydrogenation, loss of O, ketone, glycine conjugation, glucuronide conjugation and their composite reactions. The results provide valuable evidence for elucidation the potential mechanism of oroxin B pharmacological action, and offer reasonable guidelines for further investigations of oroxin B safety and efficacy.

Li S, Pei W, Guo T, Zhang H. Distributions of eight bioactive components in rat tissues administered Marsdenia tenacissima extract orally detected through UPLC-MS/MS. Biomed Chromatogr 2020; 35:e5034. [PMID: 33226666 DOI: 10.1002/bmc.5034] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2020] [Revised: 11/17/2020] [Accepted: 11/20/2020] [Indexed: 12/22/2022]
Abstract
Marsdenia tenacissima (Roxb.) Wight et Arn. (M. tenacissima) is considered an anticancer medicine in traditional Chinese medicine, which is extensively used in clinical application since it has great therapeutic effects. Currently, although a number of articles have examined M. tenacissima in terms of its pharmacology and quality control, few have investigated the in vivo mechanism of M. tenacissima active ingredients. Previously, we have studied the pharmacokinetics of eight active ingredients after oral administration of M. tenacissima extracts in rat plasma. This study constructed a new scientific ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) approach to simultaneously quantify the contents of tenacissosides B, G, H and I, cryptochlorogenic acid, chlorogenic acid, neochlorogenic acid and caffeic acid in rats orally administered M. tenacissima extract. The proposed approach was successfully used for investigating the distributions of those eight analytes in rat tissues, with digoxin being used as an internal control. The Eclipse Plus C18 RRHD column was used for determination at a column temperature of 30°C. The mobile phase system consisted of acetonitrile and water (supplemented with 0.1% formic acid) under optimal gradient elution conditions. Afterwards, this approach was validated according to the requirements for the analysis of biological samples developed by the US Food and Drug Administration, including precision, accuracy, stability and matrix effects. Based on tissue distribution analysis, those eight analytes showed rapid distribution within all the tested tissues. With regard to organic acid distribution, it followed the order stomach > liver > kidney > small intestine > lung > spleen > heart, whereas the four steroids followed the order stomach > lung > spleen > small intestine > liver > kidney > heart. The present study lays the theoretical foundation for the use and development of M. tenacissima in clinical practice.

Abstract
As a traditional Chinese medicine, Marsdenia tenacissima (Roxb.) Wight et Arn. plays an indispensable role in clinical practice owing to its specific efficacy in treating malignant tumors, leukocythemia, cystitis and asthma. This study aimed to establish a novel and scientific LC-MS/MS approach to simultaneously determine tenacissoside B, H, G and I, caffeic acid, cryptochlorogenic acid, chlorogenic acid and neochlorogenic acid from M. tenacissima extract within the rat plasma samples. Digoxin was used as the internal reference. All determinations were carried out using the Eclipse Plus C18 column, and water (containing 0.1% formic acid) was used as the mobile phase A, while acetonitrile was the mobile phase B for gradient elution. The UPLC methods were validated, including calibration curves, accuracy, precision, stability and recovery of the total eight analytes, in accordance with the requirements for biopharmaceutical analysis. Moreover, the proposed approach was also used in comprehensive pharmacokinetic research on those eight analytes in rats following M. tenacissima extract gavage. According to the pharmacokinetic parameters, tenacissoside B, I, H and G are the long-acting and primary bioactive constituents in M. tenacissima extract, with long mean residence times and high concentrations. Our findings shed light on the absorption mechanism and provide significant information for the clinical application of M. tenacissima.

Integrated metabolomic and transcriptomic profiling reveals the tissue-specific flavonoid compositions and their biosynthesis pathways in Ziziphora bungeana. Chin Med 2020; 15:73. [PMID: 32695217 PMCID: PMC7364582 DOI: 10.1186/s13020-020-00354-6] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/08/2020] [Accepted: 07/11/2020] [Indexed: 12/19/2022] Open
Abstract
Background Ziziphora bungeana Juz. is a folk medicine from the Xinjiang Uygur Autonomous Region. The herb or the aerial parts of it have been used to medicinally treat cardiovascular diseases. Flavonoids are the main pharmacologically active ingredients in Z. bungeana. Identification of the tissue-specific distribution of flavonoids in Z. bungeana is crucial for effective and sustainable medicinal use of the plant. Furthermore, understanding of the biosynthesis pathways of these flavonoids in Z. bungeana is of great biological significance. Methods The flavonoids from different tissues of Z. bungeana were identified using liquid chromatography-tandem mass spectrometry (LC–MS/MS). The full-length transcriptome of Z. bungeana was determined using a strategy based on a combination of Illumina and PacBio sequencing techniques. The functions of differentially expressed unigenes were predicted using bioinformatics methods and further investigated by real-time quantitative PCR and phylogenetic relationship analysis. Results Among the 12 major flavonoid components identified from Z. bungeana extracts, linarin was the most abundant component. Nine flavonoids were identified as characteristic components of specific tissues. Transcriptome profiling and bioinformatic analysis revealed that 18 genes were putatively involved in flavonoid biosynthesis. The gene expression and phylogenetic analysis results indicated that ZbPALs, Zb4CL3, ZbCHS1, and ZbCHI1 may be involved in the biosynthesis of the main flavonoid intermediate. ZbFNSII, ZbANS, and ZbFLS may be involved in the biosynthesis of flavones, anthocyanins, and flavonols, respectively. A map of the biosynthesis pathways of the 12 major flavonoids in Z. bungeana is proposed. Conclusions The chemical constituent analysis revealed the compositions of 9 characteristic flavonoids in different tissues of Z. bungeana. Linarin can be hydrolysed into acacetin to exert a pharmaceutical role. Apigenin-7-O-rutinoside is hypothesised to be the precursor of linarin in Z. bungeana. There was greater content of linarin in the aerial parts of the plant than in the whole herb, which provides a theoretical basis for using the aerial parts of Z. bungeana for medicine. These results provide a valuable reference for further research on the flavonoid biosynthesis pathways of Z. bungeana and will be significant for the effective utilisation and ecological protection of Z. bungeana.

[PMID: 32227654 DOI: 10.1002/jssc.201901169] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2019] [Revised: 03/21/2020] [Accepted: 03/21/2020] [Indexed: 01/02/2023]
Abstract
Isovitexin, a bioactive flavonoid constituent isolated from Desmodii Styracifolii, is considered an adjuvant for antiurolithiasis diseases. In this study, an ultra-high-performance liquid chromatography coupled with hybrid triple quadruple time-of-flight mass spectrometry method was developed to characterize and compare the metabolic profiling of isovitexin experimented on normal and kidney stone model rats. The comparative research indicated that 28 metabolites (18 phase I and 10 phase II) in normal rats and 33 metabolites (20 phase I and 13 phase II) in kidney stone model rats were initially identified. The results of relative quantitative determination reflected that the contents of metabolites produced by deglycosylation, reduction, and isomerization in kidney stone model rats were greater than those in healthy rats. Instead, the levels of oxidative and dehydrogenated metabolites in normal groups were higher than those in kidney stone model groups. The results of this study are valuable and important for understanding the metabolic process of isovitexin in clinical application, and especially the metabolism study in kidney stone model rats could provide a beneficial reference for the further search of effective substances associated with the treatment of kidney stones.

Abstract
Glaucocalyxin A (GLA) belongs to the natural ent-kauranoid diterpenoids family with antitumor, antifibrotic, anticoagulative, antioxidant, and anti-AD effects. In this study, ultra-high-performance liquid chromatography coupled to quadrupole time-of-flight mass spectrometry (UHPLC-Q-TOF-MS) system was applied to observe probable metabolites of GLA in vitro and in vivo firstly. The mass data were respectively obtained by two typical acquisition methods, ‘data-dependent acquisition’ (DDA) and ‘data-independent acquisition’ (DIA) modes. The combinations can not only guarantee sensitivity but also capture more precursor ions and MS/MS spectra. Then, multiple data processing techniques were applied to hunt metabolites rapidly. As a result, 32 phase I metabolites of different structures and 6 phase II metabolites were identified, including 25, 18, 17 and 7 in rat urine, feces, bile, and plasma, respectively. Besides, under the action of rat intestinal flora (RIF), 7 metabolites were detected. In the study, the main bio-transformations were oxidation and demethylation. Conjugation with methylation, sulfate, and glucuronide produced phase II metabolites. This study laid the foundation for the further study of the pharmacological effects of GLA and was conducive to mechanism research. The experimental process flow.![]()

Abstract
Although farrerol, a characteristically bioactive constituent of Rhododendron dauricum L., exhibits extensive biological and pharmacological activities (e.g., anti-oxidant, anti-immunogenic, and anti-angiogenic) as well as a high drug development potential, its metabolism remains underexplored. Herein, we employed ultra-high performance liquid chromatography/quadrupole time-of-flight mass spectrometry coupled with multiple data post-processing techniques to rapidly identify farrerol metabolites produced in vivo (in rat blood, bile, urine and feces) and in vitro (in rat liver microsomes). As a result, 42 in vivo metabolites and 15 in vitro metabolites were detected, and farrerol shown to mainly undergo oxidation, reduction, (de)methylation, glucose conjugation, glucuronide conjugation, sulfate conjugation, N-acetylation and N-acetylcysteine conjugation. Thus, this work elaborates the metabolic pathways of farrerol and reveals the potential pharmacodynamics forms of farrerol.

LC-MS/MS Method for Simultaneous Determination of Linarin and Its Metabolites in Rat Plasma and Liver Tissue Samples: Application to Pharmacokinetic and Liver Tissue Distribution Study After Oral Administration of Linarin. Molecules 2019; 24:molecules24183342. [PMID: 31540332 PMCID: PMC6766828 DOI: 10.3390/molecules24183342] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2019] [Revised: 09/07/2019] [Accepted: 09/11/2019] [Indexed: 12/11/2022] Open
Abstract
Linarin, a flavone glycoside, is considered to be a promising natural product due to its diverse pharmacological activities. Recently, it has been brought into focus for its potential to treat liver failure. In this study, a rapid and sensitive liquid chromatography electrospray-ionization tandem mass spectrometry (LC–MS/MS) method was developed and validated for the simultaneous determination of linarin and its three metabolites (acacetin, apigenin, and p-hydroxy benzaldehyde) in plasma and liver tissue samples of normal rats and rats with d-galactosamine (d-GalN)-induced liver injury. After liquid–liquid extraction (LLE) with ethyl acetate, chromatographic separation of the four analytes was achieved using an ACQUITY UPLC BEH-C18 (1.7 μm, 2.1 × 50 mm) with a mobile phase of 0.01% formic acid in methanol and 0.01% formic acid at a flow rate of 0.3 mL/min. The detection was accomplished on a tandem mass spectrometer via an electrospray ionization (ESI) source by multiple reaction monitoring (MRM) in the negative ionization mode. The method had a good linearity over the concentration range of 1.00–200 ng/mL for linarin and its metabolites. The validated method was successfully applied to the pharmacokinetic and liver tissue distribution study of linarin and its metabolites after a single oral administration of linarin (90 mg/kg) to rats.

Abstract
Cirsium setosum (Willd.) MB. has been reported to exert significant anti-hemorrhagic, anti-inflammation, antimicrobial, sedative and detoxicating efficacy. It has been widely used to treat gastrointestinal bleeding, uterine bleeding, infectious hepatitis and cardiovascular disease in China. Recent studies have shown that flavonoids are the main active components in C. setosum. Nevertheless, to the best of our knowledge, there is no report concerning the simultaneous determinations and pharmacokinetics of constituents in C. setosum flavonoids in rat plasma. In this study, a rapid, sensitive and selective triple quadrupole liquid chromatography-mass spectrometry method was developed to determine eight analytes from the flavonoids of C. setosum in rat plasma. In addition, the pharmacokinetic study of the eight analytes in rats after oral administration of C. setosum flavonoids was successfully completed through this method. According to the pharmacokinetic parameters of the eight analytes, rutin, naringin, quercetin, acacetin, wogonin were the long-acting components of the C. setosum flavonoids, with long elimination time and high bioavailability. Of note, the method developed in this study fills a blank in pharmacokinetic studies of C. setosum flavonoids. Our findings provide valuable views on the understanding of the absorption mechanism of C. setosum flavonoids and their clinical efficacy.

Abstract
Hinokiflavone (HF), belonging to biflavonoids, possesses excellent pharmacological activities, including anti-inflammatory, antioxidant and antitumor activity. Nevertheless, its metabolism in vivo (rats) and in vitro (rat liver microsomes and intestinal flora) is presently not characterized. In this study, ultra-high-performance liquid chromatography coupled with hybrid triple quadrupole time-of-flight mass spectrometry (UHPLC-Q-TOF-MS) based on four-step strategy was a rapid method for the detection of HF metabolites. A total of 41 metabolites in vivo, 49 metabolites in vitro were characterized. It also verified that intestinal tract exceeds the liver in the biotransformation of HF. More significant, the main metabolic pathways for HF were mainly bio-transformed to various mono-flavone resulting from the rupture of connective CO bonds, which exhibited a large distinction with other biflavones. Noteworthily, glutamine conjugation and glycine conjugation were considered as unique metabolic pathways of HF. The information obtained from this study contributes to better understanding of pharmacological mechanism of HF.
