Isolation of 2-ethyl-3-methylmaleimide N-ß-D- glucopyranoside from Riesling wine
S u m m a r y : A glycosidic isolate of Riesling wine was separated with multilayer coil countercurrent chromatography (MLCCC). After acetylation and subsequent purification by high performance liquid chromatography (HPLC), the N-ß-Dglucopyranoside of 2-ethyl-3-methy lmaleimide (3-ethyl-4-methyllH-pyrrole-2,5-dione) 2 was identified for the firsttime as natural wine constituent. The identificat...
متن کاملSurvey of Argentinean human plasma for ochratoxin A.
The presence of ochratoxin A (OTA) in human blood has been reported for many countries, especially in Europe. However, so far no report exists concerning such a presence in Argentina. The aim of this study was to assess OTA concentration in human plasma in two different areas of Buenos Aires province. OTA was determined by high-performance liquid chromatography (HPLC) in 199 plasma samples from...
متن کاملIsolation and identification of secondary metabolites from the aerial parts of Stachys lavandulifolia Vahl
Stachys lavandulifolia Vahl is an herbaceous wild plant native to Iran which is traditionally used in Iranian folk medicine as a mild sedative tea for reducing anxiety and for treatment of gastrointestinal disorders. Our previous study on ethyl acetate extract of S. lavandulifolia proved anti-anxiolytic activity and so the present study was designed to determine chemical components of this biol...

متن کاملAnalysis of Ochratoxin a in Pig Tissues Using High Pressure Liquid Chromatography (hplc) and Liquid Chromatography Tandem Mass Spectrometry (lc/ms/ms) as Confirmative Methods
Two different analytical methods for the determination and confirmation of ochratoxin A (OTA) in blood serum, kidney and liver of pigs have been compared. Sample clean-up was based on liquid-liquid phase extraction. The detection of OTA was accomplished with high-performance liquid chromatography (HPLC) combined either with fluorescence detection (FL) or electro spray ionization (ESI+) tandem m...
