Abstract
Asparagus (A. officinalis L.) is a perennial herb of the genus Asparagus that is rich in nutrients. This study aimed to distinguish three cultivars of asparagus (Paladin, Grace, and Jinggang red) based on their volatile organic compounds (VOCs) and metabolic profiles. VOCs in the three cultivars were separated and identified using electronic nose (E-nose) and gas chromatography–ion mobility spectrometry (GC–IMS). Differences in metabolites among the three cultivars were analyzed using liquid chromatography-tandem mass spectrometry (LC-MS/MS). E-nose and GC-IMS showed that the VOCs in asparagus differed significantly among the three groups. E-nose result showed that purple asparagus (Jinggang red) was connected to a stronger earthy odor; green asparagus (Paladin and Grace) were shown characteristic dill flavor. Moreover, 50 VOCs were detected by using GC–IMS. Ketones and alcohols were most abundant in Paladin; methyl benzoate and dimethyl sulfide were most abundance in Grace; aldehydes and acids were most abundance in Jinggang red. Moreover, 130 and 71 different metabolites were detected in the positive and negative modes among three cultivars, such as quercetin and rutin. Functional analysis revealed that these metabolites were involved in beta-alanine metabolism and ATP-binding cassette (ABC) transporters. In summary, E-nose combined with GC-IMS and LC-MS/MS methods has good application prospects in evaluating and identifying VOCs and metabolites of different cultivars of asparagus. The identified VOCs and metabolites can provide guidelines for the development of functional asparagus products.

Tang J, Shi M, Xu Y, Ju Z, Guan H, Lin J, Li G, Han H, Zhang T. Metabolite profiling of Shuganzhi tablets in rats and pharmacokinetics study of four bioactive compounds with liquid chromatography combined with electrospray ionization tandem mass spectrometry. J Chromatogr B Analyt Technol Biomed Life Sci 2021; 1179:122827. [PMID: 34147874 DOI: 10.1016/j.jchromb.2021.122827] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2021] [Revised: 06/02/2021] [Accepted: 06/05/2021] [Indexed: 02/05/2023]
Abstract
Shuganzhi Tablets (SGZT) is developed on the basis of a clinical empirical formula as a hospital preparation for the treatment of fatty liver. In this study, a rapid and highly sensitive LC-MS/MS method was established and validated for simultaneous determination of ginsenoside Re, ginsenoside Rg1, notoginsenoside R1, naringin, specnuezhenide, emodin, polydatin, hesperidin and saikosaponin A in rat plasma. Multiple reaction monitoring mode played an important role in simultaneous quantitative analysis of multiple components. The analytes were separated by the action of an ACQUITY UPLC® BEH C18 column (2.1 × 50 mm, 1.7 μm) in five minutes. The validated LC-MS/MS method was successfully applied to the pharmacokinetic analysis of hesperidin, emodin, polydatin and naringin of SGZT in rat plasma after administration. A UHPLC system couple with a quadrupole combined with time of flight mass spectrometer was used for qualitatively analyzing of the composition of SGZT and its metabolites in serum, urine, bile and feces of rats. The results showed that a total of 65 components were detected in rat biological samples, including 10 prototype components and 55 metabolites. It was speculated that the ingredients of SGZT experienced mainly the following reactions in rats: phase I reaction such as hydrolysis, oxidation, hydroxylation, carboxylation and dehydroxylation and phase Ⅱ reaction such as glucuronidation and sulfation. These results provide useful information for the further study of its active ingredients.

A Novel Validated Injectable Colistimethate Sodium Analysis Combining Advanced Chemometrics and Design of Experiments. Molecules 2021; 26:molecules26061546. [PMID: 33799846 PMCID: PMC8000333 DOI: 10.3390/molecules26061546] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2021] [Revised: 03/04/2021] [Accepted: 03/08/2021] [Indexed: 11/16/2022] Open
Abstract
Colistimethate sodium (CMS) is widely administrated for the treatment of life-threatening infections caused by multidrug-resistant Gram-negative bacteria. Until now, the quality control of CMS formulations has been based on microbiological assays. Herein, an ultra-high-performance liquid chromatography coupled to ultraviolet detector methodology was developed for the quantitation of CMS in injectable formulations. The design of experiments was performed for the optimization of the chromatographic parameters. The chromatographic separation was achieved using a Waters Acquity BEH C8 column employing gradient elution with a mobile phase consisting of (A) 0.001 M aq. ammonium formate and (B) methanol/acetonitrile 79/21 (v/v). CMS compounds were detected at 214 nm. In all, 23 univariate linear-regression models were constructed to measure CMS compounds separately, and one partial least-square regression (PLSr) model constructed to assess the total CMS amount in formulations. The method was validated over the range 100–220 μg mL−1. The developed methodology was employed to analyze several batches of CMS injectable formulations that were also compared against a reference batch employing a Principal Component Analysis, similarity and distance measures, heatmaps and the structural similarity index. The methodology was based on freely available software in order to be readily available for the pharmaceutical industry.

Colistimethate Acidic Hydrolysis Revisited: Arrhenius Equation Modeling Using UPLC-QToF MS. Molecules 2021; 26:molecules26020447. [PMID: 33467022 PMCID: PMC7830259 DOI: 10.3390/molecules26020447] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2020] [Revised: 01/11/2021] [Accepted: 01/14/2021] [Indexed: 11/17/2022] Open
Abstract
Colistimethate (CMS), the prodrug of polymyxin E (colistin), is an antibiotic widely used as a last-line therapy against multidrug resistant Gram-negative bacteria, but little is known about its pharmacokinetics as its administration has stopped as a result of high neuro- and nephro-toxicity. The measurement of CMS levels in patients’ biological fluids is of great importance in order to find the optimal dose regimen reducing the drug toxicity. Until now, CMS assay methods are based on the indirect determination after its hydrolysis to colistin (CS). Herein, the aim is to find the optimal conditions for the complete hydrolysis of CMS to CS. The reaction was studied at accelerated conditions: 40 °C, 50 °C, and 60 °C, and the results were evaluated by assessing the Arrhenius equation and computation employing the Tenua software. A validated analytical methodology based on ultra-performance liquid chromatography (UPLC) coupled to a hybrid quadrupole time of flight (QToF) instrument is developed for the simultaneous measurement of CMS and CS. The current methodology resulted in complete hydrolysis, in contrast with the previously reported one.
