An aptamer-based lateral flow test strip was developed for the simultaneous detection of Salmonella Typhimurium, Escherichia coli O157:H7, and Staphylococcus aureus. This assay based on sandwich-type format using primary aptamer conjugated with gold nanoparticles (AuNPs) as signal probe a secondary aptamer-coated membrane capture probe. Several experimental conditions that influenced sensitivity were investigated, including NaCl concentrations loaded amounts nanoparticle–aptamer conjugates...
An in-depth investigation of the adsorption and diffusion mechanism hydrogen in low-rank coals is great significance for optimizing technical path geological storage improving efficiency storage. Two kinds coal samples with a low metamorphic degree from Foran Coal Mine Sihe were used as adsorbents, molecular structure determined experimentally, H2 molecules was analyzed atomic level based on numerical simulation. It found that aliphatic carbon mainly links aromatic ring form branched chain...
The optimal synchronous conditions to extract tea polysaccharides (TPS) and polyphenols (TPP) from Ya'an Tibetan were investigated, the antioxidative capacity of TPS TPP was measured, analyzed identify polyphenol compounds it contained. On basis single-factor experiments, a Box-Behnken design response surface methodology applied optimize hot water extraction conditions. technology determined as temperature 83°C, time 104 min, liquid-to-material ratio 41 ml/g, yielding at 42.70 ± 2.38 mg/g...
Herba Siegesbeckiae (HS), derived from the aerial parts of three plants, Siegesbeckia orientalis (SO), S. glabrescens (SG), and pubescens (SP), has been used for treatment inflammatory diseases in China centuries. In present study, hydrodistillation was applied to extract essential oils dried SO, SG, SP parts, chemical composition analysis by gas chromatography–mass spectrometry (GC-MS) led identification a total 148 compounds (56 62 59 SP). The main components differed significantly. vitro...
A chemical study on the epidermis of cultivated edible mushroom Wolfiporia cocos resulted in isolation and identification 46 lanostane triterpenoids, containing 17 new compounds (1-17). An experimental determination their anti-inflammatory activity showed that poricoic acid GM (39) most strongly inhibited NO production LPS-induced RAW264.7 murine macrophages with an IC50 value at 9.73 μM. Furthermore, induced HO-1 protein expression iNOS COX2 as well release PGE2, IL-1β, IL-6, TNF-α,...
Main observation and conclusion Four previously undescribed ent ‐abietane diterpenoids (1—4), along with eleven known analogues (5—15), were isolated from the roots of wild Euphorbia fischeriana . Their gross structures determined via extensive spectroscopic data, absolute configurations elucidated by means single‐crystal X‐ray diffraction analysis, Rh 2 (OCOCF 3 ) 4 ‐induced CD spectrum ECD calculations. cervical carcinoma inhibition activities counteract HeLa cells screened MTT assay,...
Abstract To investigate the effects of semidry milling method on quality attributes glutinous rice flour and sweet dumpling, were prepared by wet, dry milling, respectively. As a result, content damaged starch in dry‐milled was significantly higher than that wet‐milled ( P < 0.05). When tempered to 33% moisture, semidry‐milled same as wet milling. The at moisture showed similar microstructures. had properties texture cooking dumplings These results indicated protective characteristics...
Chinorlactone A (1) represents a new carbon skeleton of schinortriterpenoids featuring unique 6/5/8/5-fused carbocyclic core system that was highly oxidized and rearranged.
Sophora flavescens Ait. has been utilized as an anticarcinogen, antibacterial and insecticide. Two new prenylflavonoids, Sophoflavonoid A (1) B (2), together with four known analogues were isolated from the root bark of S. flavescens. The structures these compounds elucidated by interpretation spectroscopic data chemical evidence. Their absolute configurations determined ECD analysis. inhibitory effects 1-6 against three lung carcinoma cells using MTT assay. results revealed that compound 3...
Main observation and conclusion Chromatographic purification of Sigesbeckia glabrescens extracts led to three undescribed ent ‐pimarane diterpenoid dimers, named glabreside A—C (1—3). Their structures were confirmed by comprehensive spectroscopic analyses, the compound 1 3 X‐ray crystallography. The results anti‐inflammatory activity assay showed that C (3) exhibited most potent inhibition on nitric oxide (NO) production induced lipopolysaccharide (LPS) in BV2 microglia compared with other...
