The lowest detecting concentration of aidicarb in soil and apple was 0.004 and 0.004mg/kg,respectively. On the level of 0.1～2.0mg/kg,the average recovery and variation coefficient of aldicarb and its main metabolites were 84.7～109.7% and 1.0～7.8%, respectively.
This article mainly studied the method of residual analysis of triadimefon and triadimenol in cabbage and soil. The determination and degradation of triadimefon and its main metabolite of triadimenol in soil and cabbage were studied and the effect on degradation of triadimefon by added glucose to increase the content of organic matter of soil was also studied by gas chromatography.
The pharmacokinetics of α- and β-diastereomers of Arteether, a well-known antimalarial drug and its active metabolite dihydroartemisinin (DHA) were studied in Sprague-Dawley rats, Rhesus monkeys and human volunteers.
Biological Evaluation of a Secondary Metabolite, 9-O-methylfusarubin, from Fusarium oxysporum
Surprisingly, in the corresponding control set (cultivation of laccase-negative clone without atrazine) an unidentified metabolite having a retention time and UV-spectrum similar to those of atrazine was also found.
It has been demonstrated in model experiments that the decrease in the content of BET in the culture fluid is accounted for by the toxin interaction with an attendant product, the exogenous metabolite (EM).
Biotransformation of β-carotene with enzyme preparations isolated from the mycelium of Blakeslea trispora resulted in the formation of its hydroxylated metabolite and apocarotenals, products of oxidative degradation of this compound.
The levels of 5-hydroxyindoleacetic acid (5-HIAA), the main metabolite of serotonin (5-HT), in CSF samples of the patients were significantly lower than in those of controls.
Desacetyl-cefotaxime, the main metabolite of cefotaxime, possesses a broad antibacterial spectrum.
The application of multicolumn HPLC in the determination of residues of a new herbicide and its main metabolite in green plants, grains and straw of different cereals is demonstrated.
Determination of pyridate and its main metabolite CL-9673 in plant materials
The application of a simple reversed-phase, HPLC-UV method for the determination of the contact herbicide pyridate and its main metabolite 3-phenyl-4-hydroxy-6-chloropyridazine-known as CL-9673-in green cereals, grains and straw is described.
