Purification of Flavonolignan Diastereoisomers from Arenaria kansuensis by Two-Dimensional Liquid Chromatography Combined with Solid-Phase Extraction.[Pubmed:30753465]
J Chromatogr Sci. 2019 May 1;57(5):418-425.
Herbal plants are significant for the reason that they have a great potential in discovering drug precursors. However, how to purify compounds with higher purity from them is a question which needs to be discussed. In present study, an offline 2D reversed-phase (RP) preparative liquid chromatography coupled with solid-phase extraction (SPE) method was successfully developed for the separation of flavonolignan diastereoisomers from Arenaria kansuensis. Based on the analysis of results, the major conclusion that we have drawn from it is a RP-SPE was selected for enriching target flavonolignan sample from A. kansuensis. After that, an ODS preparative column was used for 1D preparation, and the target sample (4.6 g) was divided into five fractions with a recovery of 83.9%. Then, a C18HCE preparative column, a polar-modified RP (polar-copolymerized) type, was used for isolating flavonolignan diastereoisomers in the 2D preparation. By establishing optimal 2D chromatography, hydrophilic interaction chromatography (HILIC) columns and normal-phase (NP) columns were tested simultaneously, and the result showed that diastereoisomers are not suitable for HILIC and NP chromatography mode. Our study resulted in a tricin and five analogous derivative flavonolignans with purity >98% were successfully purified from A. kansuensis. This is the initial report of Salcolin C, Salcolin B, Tricin 4'-O-(C-veratroylglycol) ether and 5'-methoxyhydnocarpin D from A. kansuensis. In addition, it tended to be the first time that Tricin 4'-O-(C-veratroylglycol) ether is isolated from natural resource. This method has great potential for efficiently isolating flavonolignan diastereoisomers from A. kansuensis, and it shows a great prospect for the separation of flavonolignans from complex samples.
Tricin derivatives as anti-inflammatory and anti-allergic constituents from the aerial part of Zizania latifolia.[Pubmed:25559019]
Biosci Biotechnol Biochem. 2015;79(5):700-6.
Methanol extract of Zizania latifolia was partitioned with EtOAc, n-BuOH, and H2O. From the EtOAc layers, a new flavonolignan along with a known flavone and three known flavonolignans, tricin (1), salcolin A (2), Salcolin B (3), and salcolin C (4), were isolated through repeated silica gel and ODS column chromatography. The chemical structure of the new flavonolignan was determined to be tricin-4'-O-[erythro-beta-guaiacyl-(7''-O-methyl)-glyceryl] ether and was named salcolin D (5) based on physicochemical and spectroscopic data, including FT-NMR and ESI-MS. All compounds were isolated for the first time from this plant. Compounds 2-5, tricin derivatives, all exhibited higher anti-inflammatory and anti-allergy activities than tricin. In particular, salcolin D (5) was shown to have the strongest inhibitory activity against LPS-induced NO production in RAW 264.7 cells as well as beta-hexosaminidase release in IgE-sensitized RBL-2H3 cells. These results suggest that the presence of tricin derivatives conveys allergy and inflammation treatment ability to Z. latifolia.
Lignan and flavonoids from the stems of Zea mays and their anti-inflammatory and neuroprotective activities.[Pubmed:24748513]
Arch Pharm Res. 2015 Feb;38(2):178-85.
The stems of Zea mays L., otherwise known as cornstalks, were extracted with 80 % aqueous MeOH, and the concentrated extract was successively partitioned with ethyl acetate (EtOAc), normal butanol, and water. From the EtOAc fraction, a new lignan along with three known flavonoids, tricin (1), salcolin A (2), and Salcolin B (3), were isolated. The chemical structure of the lignan was determined to be tetrahydro-4,6-bis(4-hydroxy-3-methoxyphenyl)-1H,3H-furo[3,4-c]furan-1-one (4) through spectroscopic data analyses including NMR, MS, and IR. All compounds were isolated for the first time from this plant. The isolated compounds were evaluated for their inhibitory activity against NO production in Lipopolysaccharide-induced RAW 264.7 cells and their protective activity in glutamate-induced cell death in HT22 cells. The compounds 1, 2 and 4 showed anti-inflammatory effects with IC50 values of 2.63, 14.65, and 18.91 muM, respectively, as well as neuroprotective effects with EC50 values of 25.14, 47.44, and >80 muM, respectively.
A pair of chiral flavonolignans as novel anti-cyanobacterial allelochemicals derived from barley straw (Hordeum vulgare): characterization and comparison of their anti-cyanobacterial activities.[Pubmed:24034604]
Environ Microbiol. 2014 May;16(5):1238-51.
The inhibitory effect of barley straw (Hordeum vulgare) on cyanobacteria has been observed in many field and laboratory studies for over 30 years, although the compounds responsible for this anti-cyanobacterial effect have remained unknown. In this study, a pair of chiral flavonolignans were isolated from barley straw extract using a bioassay-guided isolation procedure against Microcystis sp. The structures of the allelopathic compounds were elucidated by NMR (nuclear magnetic resonance) and HPLC-MS (high performance liquid chromatography-mass spectrometry), and turned out to be salcolin A and B. The enantiomers differ in their anti-cyanobacterial abilities. Both enantiomers exhibited inhibitory effects on Microcystis sp., and the EC50 (concentration for 50% of maximal effect) of salcolin A and B were 6.02 x 10(-5) and 9.60 x 10(-5 ) mol l(-1) , respectively. Furthermore, the modes of actions of the enantiomers were investigated and compared at a single cell level by flow cytometry. Salcolin A was found to induce an increase on cyanobacterial intracellular ROS (reactive oxygen species) levels and to inhibit esterase activity, whereas Salcolin B caused leakages of cyanobacterial cytoplasms. Thus, salcolin A was more 'algistatic', and Salcolin B was more 'algicidal'. This study suggests that salcolin is the key allelochemical in barley straw's inhibitory effect on cyanobacteria and could be used as an agent in the future control of cyanobacterial harmful algae blooms.
