Metabolomics study of different parts of licorice from different geographical origins and their anti-inflammatory activities
J Sep Sci 2020 Apr;43(8):1593-1602.PMID:32032980DOI:10.1002/jssc.201901013.
Glycyrrhiza uralensis Fisch., known as licorice, is one of the most famous traditional Chinese medicines. In this study, we perform a metabolome analysis using liquid chromatography-tandem mass spectrometry to assign bioactive components in different parts of licorice from different geographical origins in Gansu province of China. Sixteen potential biomarkers of taproots from different geographical origins were annotated, such as glycycoumarin, gancaonin Z, Licoricone, and dihydroxy kanzonol H mainly exist in the sample of Jiuquan; neoliquiritin, 6'-acetylliquiritin, licochalcone B, isolicoflavonol, glycyrol, and methylated uralenin mainly exist in Glycyrrhiza uralensis from Lanzhou; gancaonin L, uralenin, and glycybridin I mainly exist in licorice from Wuwei for the first time.
Preliminary identification of the absorbed bioactive components and metabolites in rat plasma after oral administration of Shaoyao-Gancao decoction by ultra-performance liquid chromatography with electrospray ionization tandem mass spectrometry
Pharmacogn Mag 2014 Oct;10(40):497-502.PMID:25422552DOI:10.4103/0973-1296.141774.
Background: Shaoyao-Gancao decoction (SGD), a traditional Chinese medicine formula, has been used for the treatment of abdominal pain and dysmenorrhea disease in Asia over long period of time. Its effectiveness has been confirmed in clinic, but its active constituents remain unclear. Materials and methods: In this paper, a rapid, sensitive and reliable ultra-performance liquid chromatography-electrospray ionization/quadrupole-time-of-flight high-definition mass spectrometry (UPLC-ESI-Q-TOF-MS) in positive and negative ion mode were established to characterize the active constituents of SGD in vitro. The analysis was performed on a Waters UPLCTM HSS T3 (2.1 × 100 mm, 1.8 µm) using gradient elution system. Automated MetaboLynxTM technique was employed to screen for the potentially bioactive components in rat plasma after oral administration of SGD. MS/MS fragmentation behavior was proposed for aiding the structural identification of the components. Results: Based on the developed method of fingerprint analysis, an injection run of the plasma sample was finished in 15.0 min. A total of 12 compounds including 9 prototype components such as gallicacid, albiflorin, liquiritin, pallidiflorin, liquiritigenin, isoLiquiritigenin, formononetin, isolicoflavonol, Licoricone, C9H10O3 and 2 metabolites such as liquiritigenin-4'-O-glucuronide, formononetin glucuronide were identified or tentatively characterized. Of note, 3 ingredients were identified from Radix Paeoniae Alba, and 9 were from Radix Glycyrrhizae. Conclusion: The compounds found in dosed plasma could be the effective substances of SGT for treating dysmenorrheal, and may provide important experimental data for further pharmacological and clinical research of SGD. Furthermore, this work has demonstrated that the feasibility of the UPLC-ESI-Q-TOF-MS for rapid and reliable characterization of identification and structural elucidation of the chemical constituents and their metabolites from herbal medicines.
Attenuation of quorum sensing-mediated virulence of Acinetobacter baumannii by Glycyrrhiza glabra flavonoids
Future Microbiol 2015;10(12):1953-68.PMID:26582430DOI:10.2217/fmb.15.107.
Aim: To develop an alternative quorum quenching therapy against multidrug-resistant Acinetobacter baumannii. Methods & results: Activity-guided partially purified fraction (F1) from Glycyrrhiza glabra significantly (p < 0.05) reduced quorum sensing regulated virulence factors of A. baumannii viz. motility, biofilm formation and production of antioxidant enzymes. Mechanistically, F1 downregulated the expression of autoinducer synthase gene, abaI, and consequently reduced (92%) the production of 3-OH-C12-HSL as determined by ESI-MS. Q-TOF and Q-TRAP analyses suggested the presence of flavonoids viz. Licoricone, glycyrin and glyzarin as the active ingredients. Conclusion: This is the first report on quorum quenching activity of G. glabra linked to its flavonoids that downregulated the expression of abaI and attenuated quorum sensing regulated virulence of A. baumannii.
Anti-Helicobacter pylori flavonoids from licorice extract
Life Sci 2002 Aug 9;71(12):1449-63.PMID:12127165DOI:10.1016/s0024-3205(02)01864-7.
Licorice is the most used crude drug in Kampo medicines (traditional Chinese medicines modified in Japan). The extract of the medicinal plant is also used as the basis of anti-ulcer medicines for treatment of peptic ulcer. Among the chemical constituents of the plant, glabridin and glabrene (components of Glycyrrhiza glabra), licochalcone A (G. inflata), licoricidin and licoisoflavone B (G. uralensis) exhibited inhibitory activity against the growth of Helicobacter pylori in vitro. These flavonoids also showed anti-H. pylori activity against a clarithromycin (CLAR) and amoxicillin (AMOX)-resistant strain. We also investigated the methanol extract of G. uralensis. From the extract, three new isoflavonoids (3-arylcoumarin, pterocarpan, and isoflavan) with a pyran ring, gancaonols A[bond]C, were isolated together with 15 known flavonoids. Among these compounds, vestitol, Licoricone, 1-methoxyphaseollidin and gancaonol C exhibited anti-H. pylori activity against the CLAR and AMOX-resistant strain as well as four CLAR (AMOX)-sensitive strains. Glycyrin, formononetin, isolicoflavonol, glyasperin D, 6,8-diprenylorobol, gancaonin I, dihydrolicoisoflavone A, and gancaonol B possessed weaker anti-H. pylori activity. These compounds may be useful chemopreventive agents for peptic ulcer or gastric cancer in H. pylori-infected individuals.
[Chemical studies of coumarins from Glycyrrhiza uralensis Fisch]
Yao Xue Xue Bao 1991;26(2):147-51.PMID:1950571doi
This paper reports the isolation and identification of eight crystalline substances (I, II, III, IV, V, VI, VII, VIII) from the root of Glycyrrhiza uralensis Fisch. Besides the known compounds liquiritin, hexacosance, beta-sitosterol, Licoricone liquiritigenin and etc, a new constituent, named neoglycyrol was obtained by sillica gel and polyamide column chromatographic method. Its chemical structure was elucidated by means of chemical and spectrometric analysis (UV, IR, NMR and MS). Neoglycyrol, C21H18O6, yellow needles with mp 263.5-265 degrees C, possesses one methoxyl, one isopentenyl and two hydroxyls. Its diacetate derivative is C25H22O8 with mp 202-203.5 degrees C. Its dimethyl ether derivative is C23H22O6 with mp 207-208.5 degrees C. Its structure was found to be VII.
