Application of UV-visible absorption spectroscopy combined with two-dimensional correlation for insight into DOM fractions from native halophyte soils in a larger estuarine delta.[Pubmed: 29524175]
UV-visible absorption spectroscopy combined with principal component analysis (PCA) and two-dimensional correlation (2D correlation) is used to trace components of dissolved organic matter (DOM) extracted from soils in a larger estuarine delta and to investigate spatial variations of DOM fractions. Soil samples of different depths were collected from native halophyte soils along a saline gradient, i.e., Suaeda salsa Comm. (SSC), Chenopodium album Comm. (CAC), Phragmites australis Comm. (PAC), and Artemisia selengensis Comm. (ASC). Molecular weights of DOM within the SSC soil profile were the lowest, followed by the CAC, PAC, and ASC soil profiles. Humification degree of DOM within the ASC soil profile was the highest, followed by the PAC, SSC, and CAC soil profiles. DOM within the soil profiles mainly contained phenolic, carboxylic, microbial products, and aromatic and alkyl groups through the PCA, which presented the significant differentiation among the four native halophyte soil profiles. The 2D UV correlation spectra of DOM within the SSC soil profile indicated that the variations of the phenolic groups were the largest, followed by the carboxylic groups, microbial products, and humified organic materials according to the band changing order of 285 → 365 → 425 → 520 nm. The 2D UV correlation spectra of DOM within the CAC soil profiles determined that the decreasing order of the variations was phenolic groups > carboxylic groups > microbial products according the band changing order of 285 → 365 → 425 nm. The 2D UV correlation spectra of DOM within the PAC soil profile proved that the variations of the phenolic groups were larger than those of the carboxylic groups according to the band changing order of 285 → 365 nm. The 2D UV correlation spectra of DOM within the ASC soil profile demonstrated that the variations of the phenolic groups were larger than those of the other DOM fractions according to the broad cross-peak at 285/365-700 nm.
Effects of Coking Wastewater on the Growth of Five Wetland Plant Species.[Pubmed: 29147739]
In order to investigate the effect of wetland plants in the treatment of coking wastewater, Oenanthe javanica (Blume) DC (OC), Artemisia selengensis Turcz. ex Bess. (AB), Echinochloa crusgalli (L.) Beauv. (EB), Brasenia schreberi J.F.Gmel. (BG), and Lythrum salicaria L. (LL) were used to remove ammonia-nitrogen and chemical oxygen demand (COD) from coking wastewater. Results showed high concentrations (> 30%, diluted by deionized water) of coking wastewater caused decreased photosynthetic rate, transpiration rate, and relative growth rate in all studied plants. OC, BG, and LL showed higher adaptability than AB and EB. Wastewater concentrations < 30% resulted in less affected growth of OC, BG, and LL; However, AB and EB were suppressed when coking wastewater concentrations were > 15%. High concentrations of coking wastewater generated oxidative stress which resulted in increased malondialdehyde and proline contents and inhibition of superoxide dismutase. OC, BG, and LL were considered tolerable species in purifying coking wastewater (concentrations < 30%).
Ultrasound-assisted extraction of polysaccharides from Artemisia selengensis Turcz and its antioxidant and anticancer activities.[Pubmed: 27162382]
Artemisia selengensis Turcz (AST) is a perennial herb with therapeutic and economic applications in China. The effects of ultrasound-assisted extraction (UAE) parameters upon extraction yield (EY%), antioxidant and antitumor activities of the polysaccharides extracts were studied by using a factorial design and response surface methodology. The optimal conditions determined were as: ultrasonic power 146 W, extraction time 14.5 min. and extraction temperature 60 °C. The average molecular weights of two homogeneous polysaccharides (APS1 and APS2) purified by DEAE cellulose-52 and Sephadex G-100 column chromatography were 125.4 and 184.1 kDa, respectively. Monosaccharide analysis showed that APS1 and APS2 were composed of five common monomers i.e., galactose, mannose, arabinose, xylose and rhamnose and one different monomer glucose and galacturonic acid respectively, with a most abundant part in molar % of APS1 and APS2 were glucose (83.01 %) and galacturonic acid (48.87 %) while least were xylose (0.80 %) and mannose (1.73 %) respectively. The antioxidant properties were determined by evaluating DPPH, hydroxyl radical scavenging activity and reducing power which indicated both APS1 and APS2 showed strong scavenging activities and anticancer activities on HT-29, BGC823 and antitumor activity on HepG-2. As UAE improved the polysaccharides yield than CSE, meanwhile, no significant difference of polysaccharides chemical compositions. Therefore, the present study suggests that the consumption of AST leaves may beneficial for the treatment of many diseases.
Metabolic profiling of antioxidants constituents in Artemisia selengensis leaves.[Pubmed: 25976801]
This study aimed to evaluate the antioxidant potential of Artemisia selengensis Turcz (AST) leaves, a byproduct when processing AST stalk, and identify the antioxidant constituents by using HPLC-QTOF-MS(2). The total phenolics content (TPC), total flavonoids content (TFC) and antioxidant abilities of fractions resulted from the successively partition of chloroform, ethyl acetate and n-butanol were compared. Ethyl acetate fraction (EAF) exhibited the highest TFC (65.44 mg QuE/g fraction), n-butanol fraction (nBuF) showed the highest TPC (384.78 mg GAE/g fraction) and the best DPPH scavenging ability, ABTS(+) scavenging ability and reducing power. Totally, 57 compounds were identified or tentatively identified in nBuF and EAF, 40 of them were reported in AST for the first time. The major constituents in EAF were flavonoids, and the major constituents in nBuF were phenolic acids and organic acids. Thus, AST leaves might be a potential low-cost resource of natural antioxidants.
Chemical components from the haulm of Artemisia selengensis and the inhibitory effect on glycation of β-lactoglobulin.[Pubmed: 25927398]
Artemisia selengensis (AS) has been traditionally used as both food and medicine for thousands of years in China. In our studies, l-tryptophan was first isolated from the haulm of AS together with luteolin, rutin, and kaempferol-3-O-glucuronide. Their structures were elucidated by spectroscopic methods including HRMS, 1D and 2D NMR. Three flavonoid compounds showed satisfactory suppression effects on the formation of advanced glycation end products (AGEs) in β-lactoglobulin-lactose/MGO/GO model systems, and their anti-glycation activities exhibited a dose-dependent manner. Among these compounds, kaempferol-3-O-glucuronide was demonstrated to be the strongest inhibitor against the formation of AGEs.

Ten compounds, 1',3'-propanediol,2'-amino-1'-(1,3-benzodioxol-5-yl) (1), artanomaloide (2), canin (3), eupatilin (4), quercetin-3-O-β-D-glucoside-7-O-α-L-rhamnoside (5), 1,3-di-O-caffeoylquinic acid (6), isoquercitrin (7), pinoresinol-4-O-β-D-glucoside (8), scopolin (9), and isofraxidin-7-O-β-D-glucopyranoside (10) were isolated from the aerial parts of A. selengensis. The structures of compounds (1-10) were identified based on 1D and 2D NMR, including (1)H-(1)H COSY, HSQC, HMBC and NOESY spectroscopic analyses. Among them, compound 1 was isolated from this plant for the first time as a naturally occurring compound. The inhibitory activity of these isolated compounds against interleukin-6 (IL-6) production in TNF-α stimulated MG-63 cells was also examined.
