Chalcone isomerase (CHI, EC 5.5.1.6) is one of the key enzymes in the flavonoid biosynthesis pathway catalyzing the stereospecific isomerization of chalcones into their corresponding (2S)-flavanones. In this investigation, both the cDNA sequence and the genomic sequence encoding the chalcone

Chlormequat is a plant growth regulator widely used on cereals, and there is general concern that it may impair human fertility. A LC-MS/MS method for the analysis of chlormequat in milk and serum was developed and validated in connection with
Journal of chromatography. A, 1216(20), 4402-4406 (2009-03-31)
In this work a LC-MS/MS method for the determination of two quaternary ammonium growth regulators (chlormequat and mepiquat) in food is reported. The separation was based on hydrophilic interaction liquid chromatography (HILIC) without the use of ion-pair reagents. A gradient
