The objective of this study was to assess the ethyl acetate extracts Gastrodia elata Blume (GEB) on vascular tone and mechanisms involved. GEB extracted with 95% EtOH followed by a further extraction acetate. effects its ingredients isometric tensions aortic rings from rats were measured. extract induced vasodilatory effect rat aorta, which partially dependent endothelium. Four chemical compounds isolated identified as 3,4-dihydroxybenzaldehyde (DB), 4-hydroxybenzaldehyde (HB),...
This article uses investigations into two villages to scrutinise the politics of space and visuality in top-down development nostalgia tourism across Chinese countryside engineered by government since 2014. It goes beyond debate between representational non-representational approaches tourist landscape studies proposes concept ‘embodied scopic regimes’ as a more nuanced framework analysis. is argued that production current China featured coexistence entanglement three different embodied...
Buxaustroines A–N (1–14), a series of triterpenoidal alkaloids featuring novel 17(13→18)abeo motif, were obtained from the extract Buxus austro-yunnanensis. Their structures assigned based on NMR data analysis and X-ray diffraction crystallography. A putative biosynthetic pathway for one co-isolate 15 is proposed. In assessment their bioactivities, some compounds displayed protective effects against doxorubicin-induced injury myocardial cells. Preliminary structure–activity relationship...
Six undescribed macrocyclic compounds, including diarylhexanoids (1 and 2), a diarylhexanoid glucoside (3), diarylheptanoids (4 5), an aceroside (6), were isolated from the roots of Myrica nana Cheval., along with 11 known analogues (7–17). The structures elucidated by spectroscopic analysis, as well calculated optical rotatory dispersion derivatization reactions. Metabolites 1–3, rare diarylhexane skeleton, differ familiar diarylheptanoids. spasmolytic activity compounds was evaluated on...
A new bile acid tauro-16β-hydroxy-12α-sulfate-5β-cholenoic (1), along with six known ones (2–7), was isolated from the snake bile. Its planar structure and relative configuration were elucidated based on extensive spectroscopic analyses. Moreover, compound 2 showed inhibitory effect NO production in RAW 264.7 macrophages at non-cytotoxic concentration (20 μM) rate of 69.7%.
We investigate the potential of an ultrafast transverse mode switch based on silicon insulator (SOI) platform for switching applications in spatial division multiplexing (SDM) systems. The impact waveguide geometry, operation wavelength, pulse width pump and probe waves, as well temporal delay between pulses are discussed with a special focus windows switch. optimized performances further applied to node hybrid optical time division-multiplexing (OTDM) SDM system. energy Si-based is shown be...
Falcatane A (1) and B (2), 4-oxo-3,24-dinor-2,4-secooleanane- 3-oxo-24- noroleanane-type triterpenoids, together with seven known triterpenoids involving 2-hydroxy-3-oxo-24-noroleana-1,4,12-trien-28-oic acid (3) oleanolic (4), were separated from the ethyl acetate roots extract of Dolichos trilobus using column chromatography silica gel, MCI Sephadex LH-20. The compounds determined by analysis IR, NMR spectroscopic data mass spectrometry. In bioassay, all isolates showed varying degree...
The phytochemical investigation of the methanol extract Ixeris sonchifolia led to isolation and identification nine analogs, including one new guaiane-type sesquiterpenoid, named ixerinoid A (1). structure 1 was determined by extensive analysis D 2 nuclear magnetic resonance spectroscopic data, as well quantum chemical calculations. Additionally, all isolates were tested for their neuroprotective activity using oxygen-glucose deprivation/reperfusion-induced SH-SY5Y cell injury model....
The aim of this research is to establish a space optimization method with core analysis. To direct at the problem in traditional methods such as absence quantitative analysis and overall analysis, article establishes analyzes based on basic theory syntax, that is, there inevitable link between physical social activities. This not only expansion syntax's existing research, but also reliable technical support for environmental protection great site.
