‘Taro-like’ odor is an important economic trait of pumpkin species. The metabolic and molecular bases this aromatic remain largely unexplored. Therefore, in study, gas chromatography-mass spectrometry, GC-Olfactometry, RNA-seq technology were used to illuminate the differential volatile compounds, key differentially expressed genes (DEGs) leaves from two samples. Eight including (E)-2-nonenal, ...

Numerous heterocyclic compounds containing 3-pyrroline-2-one or pyrrolidine-2,3-dione core have been found in nature and showed valuable biological activities. Therefore, the synthesis of derivatives attracted more attention from organic chemists medicinal chemists. In this manuscript, 4-acetyl-3-hydroxy-1-(3-nitrophenyl)-5-phenyl-3-pyrroline-2-one has prepared via three-component reaction and,...

Purpose: This study aimed to assess the effects of sowing date and nitrogen application rate on grain yield, use efficiency (NUE), 2-acetyl-△1-pyrroline (2-AP) contents biochemical parameters related 2-AP formation in fragrant rice. Methods: A factorial split-plot arrangement treatments was set up a split-zone experiment with two factors three levels carried out for 3 years. The main plots incl...

The identification of odor-active sulfur and nitrogen compounds formed during the processing of dry fermented sausages was the objective of this study. In order to elucidate their possible origin, free amino acids (FAAs) were also determined. The volatile compounds present in the dry sausages were extracted using solvent assisted flavor evaporation (SAFE) and monitored by one and two-dimensiona...
