Quantitative determination of diterpenoid alkaloids in four species of Aconitum by HPLC.
TLDR
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
Assessment of 20 Organochlorine Pesticides (OCPs) Pollution in Suburban Soil in Tianjin, China
TLDR
Soil contamination with organochlorine pesticides has aroused worldwide concerns considering their high toxicities and long-term persistence and could be further used to evaluate the health risk associated with soil pollution. Expand
Analysis of strychnine and brucine in postmortem specimens by RP-HPLC: a case report of fatal intoxication.
TLDR
A sensitive method for the identification and quantitation of the toxic alkaloids strychnine and brucine from postmortem specimens has been established and was applied for the analysis of blood and gastric contents of a 34-year-old female who died after ingestion of a packet of herbal medicine powder containing the seeds of Strychnos nux-vomica L. Expand
Levels, Spatial Distribution and Possible Sources of Heavy Metals Contamination of Suburban Soils in Tianjin, China
TLDR
Principal Component Analysis in combination with local specific environment suggested that heavy metal contamination had different origination and wastewater and sludge irrigation, air deposition might be the most important sources. Expand
EFFECTS OF DIFFERENT ACTIVATION PROCESSES ON H2O2/TAED BLEACHING OF Populus nigra CHEMI-THERMO MECHANICAL PULP
Tetra acetyl ethylene diamine (TAED) was used as an activator in H2O2 bleaching to improve bleaching efficiency. The present work was aimed at confirming different activations for various H2O2/TAEDExpand
Simultaneous determination of four bufadienolides in human liver by high-performance liquid chromatography.
TLDR
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.
TLDR
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
Identification of Carbonates as Additives in Pressure‐Sensitive Adhesive Tape Substrate with Fourier Transform Infrared Spectroscopy (FTIR) and Its Application in Three Explosive Cases
TLDR
CaCO3 in pressure‐sensitive tape, which cannot be differentiated by scanning electron microscope/energy dispersive X‐ray spectrometer and thermal analysis, can be easily identified using FTIR. Expand
The quantitative analysis of paraquat in biological samples by liquid chromatography-electrospray ionization-mass spectrometry.
TLDR
The quantitative method developed using liquid chromatography-electrospray ionization-mass spectrometry has been successfully applied to blood and tissues samples from nine cases and can be used to detect the presence of paraquat in forensic testing. Expand
