Background: Cuscuta australis R. Br. is a parasitic herbaceous plant that obtains nutrients by forming specialized structures called haustoria to invade host plants. Methods: In this study, we elucidated the differences in gene expression regulation and metabolic characteristics between Glycine max (Glycine (L.) Merr. Var Williams) through comprehensive transcriptomic metabolomic analyses. Results: The results demonstrated significant features haustorium distal stem segments. differentially...
Among ornamental plants, the colour of petals is an important feature. However, reason for differences Rhododendron liliiflorum remains unclear. To reveal in R. liliiflorum, high-efficiency liquid chromatographic collar (UPLC–MS/MS) technology was used to study yellow and white parts liliiflorum. A total 1187 metabolites were identified petals, including 339 flavonoid metabolites. Seventy-eight types flavonoids these found along with 11 other significantly enriched substances. Combining gene...
To establish a method for the determination of eight N-nitrosamines (N-nitrosodimethylamine, N-nitrosodimethylamine, N-nitrosomethylmethylamine, N-nitrosodibutylamine, N-nitrosopropylamine, N-nitrosomorpholine, N-nitrosodianiline and N-nitrosopiperidine) in air workplace by gas chromatography-tandem mass spectrometry (GC-MS/MS) .
Tea plants, as essential health beverages, are widely recognized for their rich content of antioxidant metabolites. This study utilized metabolomics analysis techniques to compare the metabolic differences between Camellia tachangensis F. C. Zhang, gymnogyna Hung T. Chang, and sinensis (L.) O. Kunzte, aiming reveal potential activities. By applying UPLC–MS/MS technology, we analyzed metabolites in samples identified 1056 We statistical methods such orthogonal partial least squares...
Tea ranks among the top three most beloved non-alcoholic beverages worldwide and boasts significant economic health benefits. In addition to Camellia sinensis (L.) O. Kuntze, other plants in China are consumed by residents as tea drinks, which also have important value. The present study introduces one of wild species, namely, tachangensis F. C. Zhang. We analyzed changes metabolite abundance gene expression patterns C . using metabonomics transcriptomics. found 1056 metabolites, including...
Objective: To study the changes of serum metabolic profile occupational people exposed with nanometer titanium dioxide particles (TiO(2)-NPs), and to explore biomarkers injury mechanism TiO(2)-NPs health effects. Methods: From June 2020 2021, a production enterprise was selected as research site by typical sampling method, 64 in exposure group were from enterprise, 62 logistics administrative staff same control group, blood samples collected using non-anticoagulant collection tubes. After...
Objective: To develop a method for the analysis of phenylglyoxylic acid (PGA) and mandelic (MA) in urine by ultra-high performance liquid chromatography tandem mass spectrometry. Methods: The study was conducted April 2022. Urine samples were directly diluted with initial mobile phase, separated Waters HSS T3 column after passing through membrane, analyzed under negative ionization mode (ESI(-)) multiple reaction monitoring (MRM) conditions, contents PGA MA human quantitatively determined...
Objective: To establish a method for determination of acetone in urine by headspace gas chromatography-mass spectrometry. Methods: From March to June 2021, the 3.0 ml sample was placed bottle with 4.0 g anhydrous sodium sulfate and sealed. Equilibration time 30 min at 85 ℃. The separation carried out on DB-5MS column. detected mass spectrometry quantified external standard method. Results: had good linearity range 51.2-1024.0 μg/L, correlation coefficient 0.9995. detection limit lower...
