Phenoxychromone and 4-hydroxyisoflavans from the roots of Glycyrrhiza uralensis
Nat Prod Res 2022 Aug;36(15):3850-3857.PMID:33648400DOI:10.1080/14786419.2021.1892668.
In an attempt to find species specific markers, a phenoxychromone (1) and eight isoflavonoids including six isoflavans (2-7) and two isoflavanones (8 and 9) were isolated from the root of Glycyrrhiza uralensis. Among the isolated phenolic compounds, glycyurelone (1), glycyurelvanins A and B (2 and 3) were found to be undescribed while others, (-)-vestitol (4), conferol A (5), glyasperin C (6), Glyasperin D (7), (-)-licoisoflavanone (8), and (-)-3'-(γ,γ-dimethylallyl)kievitone (9) were previously reported. All compounds except 4 and 5 were prenylated and majority of these possess isoflavan scaffold with highly conserved stereo specificity at C-3 center. Structure elucidation was mainly based on extensive NMR, ECD and mass spectral data analysis.
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.
Comparative Metabolite Profiling of Wild and Cultivated Licorice Based on Ultra-Fast Liquid Chromatography Coupled with Triple Quadrupole-Time of Flight Tandem Mass Spectrometry
Chem Pharm Bull (Tokyo) 2019;67(10):1104-1115.PMID:31582630DOI:10.1248/cpb.c19-00423.
Licorice is one of the ancient and most frequently applied herbs for its diverse phytochemicals. At present, wild resources of licorice have rapidly declined with increasing demand and the proportion of cultivated products in the market is quickly growing. However, the different level in chemical composition between the wild and cultivated licorice may result in the discrepancy in quality and pharmacological activity. Therefore, an ultra-fast liquid chromatography coupled with triple quadrupole-time of flight tandem mass spectrometry (UFLC-Triple TOF-MS/MS) method combined with multivariate statistical analysis technology was employed to explore chemical composition differences. The result showed that total 63 components were identified from licorice samples. The wild and the cultivated licorice are obviously classified into two groups according to principal component analysis (PCA). PCA and partial least squared discrimination analysis (PLS-DA) were also introduced to rapidly find 14 candidate compounds between two ecotypes of licorice. Apart from glycyrrhizin, licorice saponin J2/G2, Glyasperin D and dehydroglyasperin D also could be selected as chemical markers based on t-test and variable importance in the projection (VIP) value. Our study successfully established an effective method for exploring metabolite profiling between two ecotypes of licorice and laying the foundation for distinguishing wild and cultivated licorice.
