Harvey DJ. Analysis of carbohydrates and glycoconjugates by matrix-assisted laser desorption/ionization mass spectrometry: An update for 2021-2022. MASS SPECTROMETRY REVIEWS 2024. [PMID: 38925550 DOI: 10.1002/mas.21873] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/08/2023] [Revised: 02/05/2024] [Accepted: 02/12/2024] [Indexed: 06/28/2024]
Abstract
The use of matrix-assisted laser desorption/ionization (MALDI) mass spectrometry for the analysis of carbohydrates and glycoconjugates is a well-established technique and this review is the 12th update of the original article published in 1999 and brings coverage of the literature to the end of 2022. As with previous review, this review also includes a few papers that describe methods appropriate to analysis by MALDI, such as sample preparation, even though the ionization method is not MALDI. The review follows the same format as previous reviews. It is divided into three sections: (1) general aspects such as theory of the MALDI process, matrices, derivatization, MALDI imaging, fragmentation, quantification and the use of computer software for structural identification. (2) Applications to various structural types such as oligo- and polysaccharides, glycoproteins, glycolipids, glycosides and biopharmaceuticals, and (3) other general areas such as medicine, industrial processes, natural products and glycan synthesis where MALDI is extensively used. Much of the material relating to applications is presented in tabular form. MALDI is still an ideal technique for carbohydrate analysis, particularly in its ability to produce single ions from each analyte and advancements in the technique and range of applications show little sign of diminishing.

Steroidal saponins profiling of Rohdea chinensis (Baker) N.Tanaka by high performance liquid chromatography coupled to electrospray ionization and quadrupole time-of-flight mass spectrometry. Nat Prod Res 2024; 38:169-173. [PMID: 36190791 DOI: 10.1080/14786419.2022.2130301] [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: 05/12/2022] [Accepted: 09/20/2022] [Indexed: 10/10/2022]
Abstract
The rhizome of Rohdea chinensis (Baker) N.Tanaka (RRc) is a famous folk medicine for the treatment of carbuncles and pharyngitis. Steroidal saponins (SSs) were considered to be the most abundant active constituents in RRc. However, to date, the in-depth study of SSs is still lacking. This study was aimed to investigate the SSs profiles of RRc extract by HPLC-ESI-QTOF-MS/MS. Analysis was performed on an Agilent poroshell 120 EC-C18 column (2.1 mm × 100 mm, i.d., 2.7 μm) with 0.1% formic acid aqueous solution and acetonitrile as the mobile phase under gradient conditions. The results showed that 32 SSs including 20 furospirostanol, 11 spirostanol and 1 pseudo-spirostanol saponins were identified, 5 of which were reported in this plant for the first time. This is the first report on the analysis of SSs in RRc. This novel analysis method may stimulate further research regarding the identification of SSs in other plant species.

Abstract
Chemical constituent investigation on the n-BuOH extract of the rhizomes of Tupistra chinensis Baker leads to the isolation of ten compounds including eight undescribed furostanol saponins, tupischinosides A - H, and two known ones. The structures of isolated compounds were determined by extensive spectral analysis and chemical evidences. Interestingly, tupischinosides A and B, C and D, E and F, G and H were identified as four pairs of epimers. The cytotoxicity of tupischinosides A - H against human cancer cell lines U87, SHG44, U251, LN229 and HepG-2 was evaluated by CCK-8 method. As a result, tupischinosides A and C exhibited significant proliferation inhibitory effect on the tested cancer cells. On the contrary, the corresponding epimers, tupischinosides B and D, which only differ in the configuration of C-23 didn't exhibit any cytotoxicity to cancer cells. These results indicated that the stereochemistry of C-23 was crucial to the activity of the compounds.

Abstract
As a kind of rare plant with important medicinal value and breeding value, Rohdea wattii usually grow in dark and damp places. In this study, we reported the complete chloroplast genome of R. wattii. We used a variety of bioinformatics analysis methods to analyze and visualize the chloroplast genome and phylogenetic relationships. A typical quadripartite structure was observed in the chloroplast genome of R. wattii with a genome size of 156,487 bp. The length of the large single-copy region (LSC) was 84,969 bp, which was the longest region among the four regions; the second longest was the Inverted repeat region (IR) with 26,451 bp in length; and the smallest was the small single-copy region (SSC) with 18,616 bp in length. The overall GC content of R. wattii chloroplast genome is 37.61%. In addition, a total of 132 genes were identified in the whole genome of R. wattii, which include 86 protein-coding genes, 38 tRNA genes, and eight rRNA genes. Finally, by constructing a phylogenetic tree to analyze the phylogeny of R. wattii, and it indicated that R. wattii and Rohdea chinensis are a close evolutionary relationship.
