Quantitative determination of diterpenoid alkaloids in four species of Aconitum by HPLC.
The results indicated that contents of alkaloids in Aconitum varied significantly from species to species; hence quality control of A Conitum drugs is very necessary. Expand
Simultaneous determination of three aconitum alkaloids in urine by LC-MS-MS.
The method was employed in the analysis of the urine of a 55-year-old male who died after ingestion of herbal medicine powder made from the roots of aconite, and crassicauline A and foresaconitine were identified in the urine. Expand
Simultaneous determination of four bufadienolides in human liver by high-performance liquid chromatography.
The developed method for the simultaneous quantitation of four bufadienolides-cinobufotalin, bufalin, cinobufagin and resibufogenin-in human liver was successfully applied to a lethal poisoning case. Expand
Determination of triptolide and triptonide in human plasma by high-performance liquid chromatography.
The developed method was applied to the determination of triptolide and triptonide concentration in a patient's plasma after taking the medicament containing Tripterygium wilfordii Hook. Expand
