Simultaneous Quantification of 66 Compounds in Two Tibetan Codonopsis Species Reveals Four Chemical Features by Database-Enabled UHPLC-Q-Orbitrap-MS/MS Analysis

Molecules, Год журнала: 2024, Номер 29(21), С. 5203 - 5203

Опубликована: Ноя. 3, 2024

Codonopsis canescens Nannf. (CoC) and nervosa (CoN) are two traditional Tibetan medicinal herbs (Zangdangshen), which have been widely used in the treatment of various diseases. In this study, their aerial underground parts were systematically analyzed using database-enabled UHPLC-Q-Orbitrap-MS/MS technology. This technology introduced three adduct ions, [M − H]−, + H]+, NH4]+, to putatively identify a total 66 compounds. During putative identification, at least 16 isomers successfully differentiated, such as isochlorogenic acid A vs. B C. Thereafter, all these identified compounds further quantified for contents based on linear regression method. Their observed vary from 0.00 39,127.03 µg/g. Through multiple comparisons quantification results, study found following four chemical features: (1) Four sesquiterpenes (especially atractylenolide III) enriched mainly CoC rarely CoN; (2) quinic derivatives abundant part species; (3) sixteen flavonoids (particularly diosmetin chrysoeriol) showed higher content than (4) lobetyolin was ubiquitously distributed both CoN. Based features relevant principles, (lobetyolin, III, diosmetin, recommended quality markers species. All findings can facilitate sustainable development control herbs.

Database-aided UHPLC-Q-orbitrap MS/MS Strategy Putatively Identifies 52 Compounds from Wushicha Granule to Propose Anti-counterfeiting Quality-markers for Pharmacopoeia

Research Square (Research Square), Год журнала: 2023, Номер unknown

Опубликована: Июль 25, 2023

Abstract Wushicha Granule, an over-the-counter-drug (OTC) prescription, consists of 19 traditional Chinese herbals medicines (CHMs), such as Chaihu, Hongcha, Chuanxiong, Houpo, and Gancao. The five however have not been effectively characterized by the quality-markers (Q-markers) system in current Pharmacopoeia. study therefore established a novel database-aided ultra-high performance liquid chromatography-quadrupole-orbitrap mass spectrometry (UHPLC-Q-orbitrap MS/MS) strategy. strategy has putatively identified 52 compounds from mainly including flavonoids, saponins, alkaloid, lignins, lactones. Especially, saponin “glycyrrhetinic acid” Granule was specifically 18β-configuration (rather than 18α-configuration). Meanwhile, two pairs isomers were fully discriminated, vitexin vs isovitexin daidzein 7,4'-dihydroxyflavone. 8β-Glycyrrhetinic acid, together with saikosaponin A, alkaloid caffeine, lactone S -senkyunolide lignin magnolol, further studied using quantum chemical calculation, UV-vis spectra, anti -counterfeiting validation experiment. In experiment, they successfully recognized 6 counterfeit Granules, means LC-MS equipped extraction software. Based on these results, 8β-glycyrrhetinic acid is recommended to replace old Q-marker acid”; while S- senkyunolide magnolol are new Q-markers. These recommendations can only recognize counterfeits regarding Gancao, but also prevent possible safety-incident. All will greatly improve efficiency specificity

Integrated Uhplc-Q-Exactive-Orbitrap Ms/Ms and Abts Analyses Screen Antioxidant and Anti-Counterfeiting Marker of Eucommiae Cortex (Duzhong) for Pharmacopoeias

Опубликована: Янв. 1, 2024

Eucommiae Cortex (Duzhong) has been collected in the several Pharmacopoeias. However, its Pharmacopoeia quality-marker is outdated and unreasonable. The study therefore used database-aided ultra-high-performance liquid chromatography coupled with hybrid quadrupole-orbitrap tandem mass spectrometry (UHPLC-Q-Exactive-Orbitrap MS/MS) analysis, to putatively identify 33 compounds from Cortex. Especially, 14 "unexcavated" were detected out for first time; Meanwhile, all monocaffeoylquinic acid isomers (i.e., 1-O-, 3-O-, 4-O-, 5-O- caffeoylquinic acids) have strictly distinguished each other three dicaffeoylquinic (1,3-O-, 3,5-O-, 4,5-O- as well. All identified further subjected a semi-quantification through which chloesteryl acetate (4.11 ± 0.46%), sucrose (3.53 0.063%), (-)-syringaresinol (2.81 1.31%) found be highly abundant. Furthermore, results integrated ABTS+• antioxidant assay calculate contribution of individual compounds. (-)-Syringaresinol, neochlorogenic acid, vanillic chlorogenic (-) pinoresinol proven top five contributors, their values 97.50, 46.31, 40.57, 35.05, 30.90. Of was proposed additional pharmacopoeia Q-marker good testability traceability. not only enhances pharmacological relevance, but also can effectively recognize counterfeiting via analysis.
