Characterization of metabolites in microsomal metabolism of aconitine by high-performance
Aconitine (AC) is a bioactive alkaloid from plants of the genus Aconitum, some of which have been widely used as medicinal herbs
for thousands of years. AC is also well known for its high toxicity, which induces severe arrhythmias leading to death. The study of
metabolic pathways is very important for efficacy of therapy and evaluation of toxicity for those with narrow therapy windows.

Simultaneous Screening and Quantitation of Amphetamines in Urine
The aim of our work was to obtain the metabolic pathways of AC by the human liver microsomes.

by On-line SPE-LC/MS Method The new SAMHSA guidelines, implemented in Oct 2010, allow the use of LC/MS and LC/MS/MS for the screening, confirmation and quantitation of illicit drugs, including amphetamines. The objective of this study was to develop an on-line SPE-LC/MS method for analysis of five amphetamines in urine without sample pre-treatment except dilution with water. Simultaneous analysis for forensic drugs in human blood and urine using ultra-high speed LC-MS/MS The simultaneous analysis of drugs of abuse in clinical and forensic laboratories requires highly specific system. Conventional procedures to analyze drugs in complex matrices like whole blood involve ted
