Cell membrane chromatography coupled online with LC-MS to screen anti-anaphylactoid components from Magnolia biondii Pamp. targeting on Mas-related G protein-coupled receptor X2
J Sep Sci 2020 Jul;43(13):2571-2578.PMID:32281296DOI:10.1002/jssc.202000014.
Mas-related G protein-coupled receptor X2 was a mast cell-specific receptor mediating anaphylactoid reactions by activating mast cells degranulation, and it was also identified as a target for modulating mast cell-mediated anaphylactoid and inflammatory diseases. The anti-anaphylactoid drugs used clinically disturb the partial effect of partial mediators released by mast cells. The small molecule of Mas-related G protein-coupled receptor X2 specific antagonists may provide therapeutic action for the anaphylactoid and inflammatory diseases in the early stage. In this study, the Mas-related G protein-coupled receptor X2 high expression cell membrane chromatography was coupled online with liquid chromatography and mass spectrometry and successfully used to screen anti-anaphylactoid components from Magnolia biondii Pamp. Fargesin and Pinoresinol dimethyl ether were identified as potential anti-anaphylactoid components. Bioactivity of these two components were investigated by β hexosaminidase and histamine release assays on mast cells, and it was found that these two components could inhibit β hexosaminidase and histamine release in a concentration-dependent manner. This Mas-related G protein-coupled receptor X2 high expression cell membrane chromatography coupled online with liquid chromatography and mass spectrometry system could be applied for screening potential anti-anaphylactoid components from natural medicinal herbs. This study also provided a powerful system for drug discovery in natural medicinal herbs.
Development of a comprehensive quality control method for the quantitative analysis of volatiles and lignans in Magnolia biondii Pamp. by near infrared spectroscopy
Spectrochim Acta A Mol Biomol Spectrosc 2020 Apr 5;230:118080.PMID:31982656DOI:10.1016/j.saa.2020.118080.
The quality of drug is vital to its curative effect, thus it is important to develop a comprehensive quality control method for commonly used drugs. In this study, we developed a Gas chromatography-mass spectrometry separation method for the qualitative and quantitative analysis of volatiles, together with a High-performance liquid chromatography-mass spectrometry separation method for lignans in Magnolia biondii Pamp.. 79 volatiles and 11 lignans were identified via comparing their chromatographic behavior and mass spectra data with those in the literature. The methods were then used to determine the contents of volatiles (1, 8-cineole, d-Limonene, α-terpineol, linalool, L-camphor brain and bornyl acetate) and lignans (epieudesmin, magnolin, epi-magnolin A and fargesin) in Magnolia biondii Pamp.. Subsequently, 13 qualitative models including volatiles (1, 8-cineole, d-Limonene, α-terpineol, linalool, L-camphor brain and bornyl acetate), water-soluble extractive, lignans (Pinoresinol dimethyl ether, magnolin, epi-magnolin A and fargesin) and moisture were developed by Near-Infrared Spectroscopy based on partial least square regression herein. The reference values were obtained by High-performance liquid chromatography, Gas chromatography and etc., while the predicted values were attained from the NIR spectrum. Compared with the traditional detection methods, NIR technique methodology significantly improved the ability to evaluate the quality of Magnolia biondii Pamp., which had the advantages of convenience, celerity, highly efficiency, low cost, no harm to samples, no reagent consumption, and no pollution to the environment. Moreover, the systematic analysis method combined pharmaceutical analysis with pharmacochemistry was proposed to prepare volatiles, water-soluble extractive and lignans parts from the same sample. This way could extract more index components to be beneficial in the quality control of Magnolia biondii Pamp. roundly.
Tryptamine derived amides and acetogenins from the seeds of Rollinia mucosa
J Nat Prod 1999 Aug;62(8):1119-22.PMID:10479316DOI:10.1021/np990118x.
Bioactivity-directed fractionation of a CHCl(3)-MeOH (1:1) extract prepared from the seeds of Rollinia mucosa led to the isolation of a mixture of eight novel tryptamine amides. Extensive HPLC allowed the isolation of the major component of the mixture, which was characterized as N-lignoceroyltryptamine (6) using a combination of spectroscopic and chemical methods. The minor amides were identified by GC-MS analysis as N-palmitoyltryptamine (1), N-stearoyltryptamine (2), N-arachidoyltryptamine (3), N-behenoyltryptamine (4), N-tricosanoyltryptamine (5), N-pentacosanoyltryptamine (7), and N-cerotoyltryptamine (8). Two lignans (Pinoresinol dimethyl ether and magnolin) and six acetogenins [membranacin (9), desacetyluvaricin (10), rolliniastatin 1, bullatacin, squamocin, and motrilin] were also isolated. The cytotoxicity of membranacin (9) and desacetyluvaricin (10) against six human solid tumor cell lines was determined. The absolute configuration of the former is reported.
Isolation and purification of lignans from Magnolia biondii Pamp by isocratic reversed-phase two-dimensional liquid chromatography following microwave-assisted extraction
J Sep Sci 2007 Oct;30(15):2370-81.PMID:17628872DOI:10.1002/jssc.200700098.
The dried flower buds of Magnolia biondii Pamp are one of the most widely used medicinal plants officially listed in the Chinese Pharmacopoeia. A 2-D column-switching system without sample loop trapping, where two columns were switched directly via a six-port two-position switching valve, was successfully applied for the first time to the isolation and purification of five lignans including Pinoresinol dimethyl ether, magnolin, epi-magnolin A, fargesin, and demethoxyaschantin from M. biondii Pamp after microwave-assisted extraction. The introduction of the six-port switching valve instead of sample loop assured 100% recovery from the first dimension to the second, and the injection volumes of the second dimension could reach 12 mL. In this mode of operation, the solvent consumption of the 2-D approach was less than 30% that of conventional gradient methods with even larger sample size. The simultaneous operations of the two dimensions allowed the cycle time to be less than 16 min, compared to 90 min in the gradient elution single-dimension mode of operation. All of the five lignans were isolated at high purities of over 99% with approximately 95% recoveries.
