Microwave-assisted extraction and HPLC-DAD determination of drugs of abuse in human plasma.
A sample preparation procedure using microwave energy is proposed for the determination of morphine, 6-acetylmorphine, codeine, cocaine, cocaethylene, benzoylecgonine, methadone, and 2-ethylene-1,5-dimethyl-3,3-diphenylpyrrolidine in human plasma. A screening asymmetrical factorial design was used to identify the most suitable extraction conditions as regards solvent, temperature, and extractio...
متن کاملTyrosinase Biosensor Used for the Determination of Catechin Derivatives in Tea: Correlation with HPLC/DAD Method
Tea, one of the most popular consumed worldwide beverages, is known to be rich in polyphenols, more particularly in catechins. An amperometric biosensor based on tyrosinase was developed in order to monitor the phenolic content in black and green teas. The enzyme was immobilised by coreticulation with glutaraldehyde on carbon screen-printed electrodes (CSPE). Initially, the performances of the ...

متن کاملDetermination of Flavanones in Orange Juices Obtained from Different Sources by HPLC/DAD
Flavanones (hesperidin, naringenin, naringin, and poncirin) in industrial, hand-squeezed orange juices and from fresh-in-squeeze machines orange juices were determined by HPLC/DAD analysis using a previously described liquid-liquid extraction method. Method validation including the accuracy was performed by using recovery tests. Samples (36) collected from different Brazilian locations and bran...
