In this study, a flavor imitation method for Osmanthus fragrans aroma was developed based on molecular docking screening and odor activity value (OAV) analysis. A range of 41 volatile compounds defined through headspace solid-phase microextraction (HS-SPME) analysis O. dry powders gas chromatography-mass spectrometry (GC-MS) determination its essential oil. Molecular performed using these with ten chosen olfactory receptors (ORs) related to floral aroma, heat map constructed the cluster...
Two polysaccharide fractions were successfully isolated from the crude exopolysaccharide (EPS) of Scleroderma areolatum via gel filtration chromatography. Size exclusion chromatography/multi-angle laser light scattering (SEC/MALLS) analysis showed that weight average molecular weights (Mw) these was 3.162 ȕ 106 (Fr-I) and 2.613 (Fr-II). Both EPS exhibited a compact globular structure in aqueous solution. Monosaccharide composition revealed they primarily composed mannose glucuronic acid....
Gut microbiome influences tumorigenesis and tumor progression through regulating the microenvironment (TME) modifying blood metabolites. However, mechanisms by which gut metabolites regulate TME in multiple myeloma (MM) remain unclear. By employing16S rRNA gene sequencing coupled with metagenomics ultra-performance liquid chromatography quadrupole time-of-flight mass spectrometry, we find that Lachnospiraceae are high phosphatidylcholine (PC) low MM patients. We further show inhibits PC...
We report on a green procedure for the synthesis and stabilization of gold nanoparticles (AuNPs) from chlorauric acid (HAuCl4) with use β-glucan known as Lentinan (LNT) without external reducing or stabilizing agents in aqueous medium. LNT adopted triple helical conformation water, which was first denatured into single chains (s-LNT) at high temperature 140 °C before mixing HAuCl4. Results UV–vis absorption spectroscopy, transmission electron microscopy (TEM), energy dispersive X-ray (EDX)...
Tebuconazole is a chiral triazole fungicide used globally in agriculture as racemic mixture, but its enantiomers exhibit significant enantioselective dissimilarities bioactivity and environmental behaviors. The steric hindrance caused by the tert-butyl group makes it great challenge to synthesize tebuconazole enantiomers. Here, we designed simple chemoenzymatic approach for asymmetric synthesis of (R)-tebuconazole, which includes biocatalytic resolution epoxy-precursor...
An acidic extracellular polysaccharide (EPS) was gained from Stropharia rugosoannulata fermentation broth by the alcohol precipitate method. Sulfated derivative of EPS (S-EPS) chlorosulfonic acid-pyridine method and conditions were as follows: pyridine reaction solvent, temperature 80 °C, time 90 min. The chemical structure chain conformation S-EPS characterized FT-IR, NMR size exclusion chromatography (SEC) coupled with multi-angle laser light scattering (MALLS) detection. FT-IR spectra...
The effect on different three carbon source (i.e. glucose, fructose and sucrose) production, chemical characterization antioxidant activity of exopolysaccharide (EPS) produced by Phellinus vaninii Ljup was investigated in this study. Amongst sources examined, glucose sucrose were favorable for the mycelia growth, while maximum EPS yield achieved when employed. predominant carbohydrate compositions EPSs identified gluconic acid, mannose galactose acid. Then, FT-IR spectral analysis revealed...
A water-soluble polysaccharide (GLP-2) was isolated and purified from Ganoderma lucidum by the microwave-assisted freeze-thaw method. Microwave-assisted rapid thawing treatment can greatly improve extraction yield of polysaccharides. The chemical structure GLP-2 analyzed with FT-IR, HPLC, GC-MS, NMR spectrometry. It proved that is mainly composed β-1,3-glucose β-1,6-glucose. chain conformation SEC-MALLS-RI, indicating adopts semi-rigid conformation. Its molecular weight 16.7 × 104, its size...
Two new compounds, versicolones A and B (1 2), three known pyrone derivatives (3-5) were isolated from the insect-associated fungus Aspergillus versicolor.
