High Performance Liquid Chromatography:Article Title: Biodegradation of Clomazone in a California Rice Field Soil: Carbon Allocation and Community Effects Article Snippet: Degradation pathways for the herbicide clomazone in a California rice field soil were characterized via pulselabeling of anaerobic (flooded) and aerobic (moist) soil microcosms.. Clomazone-derived C in the major C pools of a rice ecosystem and soil phospholipid fatty acid (PLFA) profiles were analyzed over time to determine if (1) the compound accumulates in the microbial biomass, (2) it affects temporal microbial population dynamics, and (3) it is either preferentially metabolized or cometabolized.. In anaerobic microcosms, the compound was rapidly biotransformed to ring-open clomazone, upon which it persisted in the aqueous phase, whereas aerobic microcosms degraded it slower but a greater percentage was mineralized.

Article Snippet: A highly sensitive and uncomplicated method of analyzing steroidal hormones in river and estuarine water samples was developed using a liquid chromatography tandem mass spectrometer equipped with an electrospray ionization (ESI) source and atmospheric pressure photoionization (APPI) source.. Steroidal hormones included not only estrogen but also androgen and conjugates of these two.. APPI displayed greater sensitivity than ESI for most of the unconjugated steroids examined, with very high sensitivity for testosterone and 4-androstene-3,17-dione in particular.

Strain QM49 ?-Glucosidase and Its Use in the Production of the Pharmaceutically Active Minor Ginsenosides ( S )-Rh 1 and ( S )-Rg 2 Article Snippet: Electrospray ionization mass spectra (ESI-MS) were measured for the purified biotransformed ginsenosides [( S )-Rg 2 and ( S )-Rh 1 ] using a Article Title: Determination of prostatic androgens in 10 mg of tissue using liquid chromatography-tandem mass spectrometry with charged derivatization. Article Snippet: A practical liquid chromatography–tandem mass spectrometric (LC-MS-MS) method for the determination of prostatic 5a-dihydrotestosterone (DHT) and testosterone (T) has been developed.. The prostatic androgens were extracted with MeOH–H2O (3: 7, v/v), purified with an Oasis HLB cartridge, derivatized with the permanently charged reagent 2-hydrazino-1-methylpyridine (HMP), and subjected to LC–MS-MS analysis using electrospray ionization (ESI) operated in the positive ion mode.. The derivatization with HMP was very effective at increasing the detectability using the positive-ESI-MS. Article Title: Multiclass analysis of illicit drugs in plasma and oral fluids by LC-MS/MS. Article Snippet: An analytical procedure for the simultaneous determination in human plasma and oral fluids of several illicit drugs belonging to different chemical and toxicological classes is presented.. Amphetamine, methamphetamine, morphine, 6-monoacetylmorphine, methylenedioxyamphetamine, methylenedioxyethylamphetamine, methylenedioxymethamphetamine, cocaine, benzoylecgonine, tetrahydrocannabinol, carboxytetrahydrocannabinol, ketamine, and phencyclidine have been quantified in real samples using a very rapid sample treatment, basically a protein precipitation.. The quantitative analysis was performed by liquid chromatography–tandem mass spectrometry and has been fully validated. |
