A multiresidue method for simultaneous determination of 44 organophosphorous pesticides in Pogostemon cablin and related products using modified QuEChERS sample preparation procedure and GC-FPD.
The developed QuEChERS method was proved to be simple, fast, accurate, low cost and environmentally friendly and can be successfully applied in the determination of targeted OPP residues in P. cablin and its related products. Expand
A gold/Fe3O4 nanocomposite for use in a surface plasmon resonance immunosensor for carbendazim
AbstractA surface plasmon resonance (SPR) biosensor for the pesticide carbendazim is described that has enhanced performance due to the use of a Au/Fe3O4 nanocomposite as an amplifying label on theExpand
Multi-elements determination in medical and edible Alpinia oxyphylla and Morinda officinalis and their decoctions by ICP-MS.
The results showed that decoction of the samples may reduce the intake of heavy metals and the transfer ratios of selected elements from both species of herbs into their decoctions were reduced. Expand
Multi-residue analysis of 26 organochlorine pesticides in Alpinia oxyphylla by GC-ECD after solid phase extraction and acid cleanup.
A simple and effective multi-residue method was developed and validated for the analysis of 26 organochlorine pesticide residues in Alpinia oxyphylla by a gas chromatography with an electron capture detector (GC-ECD) and 3 samples were found to be positive with four pesticides. Expand
Oriented assembly of surface plasmon resonance biosensor through staphylococcal protein A for the chlorpyrifos detection
The results presented here indicate that the SPA-modified sensor chip can successfully improve the and obviating the need of the modification of the antibody, and has the great potential for rapid, sensitive, and specific detection with broad applications in areas of environmental monitoring and food safety.

[Determination of ochratoxin A in human urine by HPLC-FLD after cleaned-up by molecularly imprinted polymer solid phase extraction column].
A method was developed for the determination of ochratoxin A in human urine by HPLC-FLD after molecularly imprinted polymer solid phase extraction (MIP-SPE) column that is simple, rapid and reliable and can be used to determine the contents of OTA inhuman urine. Expand
Gas chromatography with flame photometric detection of 31 organophosphorus pesticide residues in Alpinia oxyphylla dried fruits.
A simple, rapid and effective gas chromatography-flame photometric detection method was established for simultaneous multi-component determination of 31 organophosphorus pesticides (OPPs) residues inExpand
GC-FID coupled with chemometrics for quantitative and chemical fingerprinting analysis of Alpinia oxyphylla oil.
The developed gas chromatography-flame ionization detection (GC-FID) method showed good specificity, linearity, reproducibility, stability and recovery, and could be used satisfactorily for quantitative analysis. Expand
A simple multi-residue method for determination of plant growth retardants in Ophiopogon japonicus and soil using ultra-performance liquid chromatography-tandem mass spectrometry.
An effective and reliable method for simultaneous determination of 11 plant growth retardants in Ophiopogon japonicus and soil samples was developed by ultra-performance liquid chromatography-triple quadrupole tandem mass spectrometry (UPLC-QqQ-MS/MS). Expand
Simultaneous Analysis of Iridoid Glycosides and Anthraquinones in Morinda officinalis Using UPLC-QqQ-MS/MS and UPLC-Q/TOF-MSE
A selective and sensitive method was developed for determining six target compounds in M. officinalis by UPLC-MS/MS and will be helpful for quality control and identification main compounds of M. Officinalis. Expand
