[Determination of benzo[a]pyrene in vegetable oils by HPLC coupled with matrix solid phase dispersion].
Determination of benzo(a)pyrene in vegetable oils was carried out using aluminium oxide for clean-up followed by reverse phase high performance liquid chromatographic (HPLC). A quantity of oil was dissolved in petroleum ether and added to an aluminium oxide column which retained the lipids. Benzo(a)pyrene in the oil was eluted from the column with petroleum ether and the collected eluate was co...
متن کاملdetection of volatile compounds of medicinal plants with some nano-sorbents using modified or new methodologies and investigation of antioxidant activity of their methanolic extracts
in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...
Determination of Malathion and α-Endosulfan Residue in Khazar Rice Using Matrix Solid Phase Dispersion and HPLC
An extraction method based on matrix solid phase dispersion (MSPD) and high performance liquid chromatography with UV detection for quantification of two widely used pesticides (Malathion and α-Endosulfan) in Khazar rice from north of Iran were investigated. The ratio of solid phase (adsorbent) to sample, types of eluting solvent and its volume were optimized to achieve the highest recoveries f...
متن کاملMatrix Solid-Phase Dispersion versus Ultrasound Assisted Extraction with Solid-Phase Extraction in the HPLC Analysis of Furanocoumarins from Fruits of Archangelica officinalis Hoffm
Neste estudo, um eficiente método, a dispersão da matriz em fase sólida (DMFS), foi usado para a determinação simultânea de furanocoumarinas de frutos de Archangelica officinalis Hoffm. Amostras da planta foram preparadas pelo procedimento MSPD otimizado, utilizando C18 como sorvente. A análise foi realizada por cromatografia líquida de alta eficiência com detector de arranjo de diodos (HPLC-DA...
متن کاملMatrix Solid-Phase Dispersion Extraction and Quantification of Alpinetin in Amomum Seed using Validated HPLC and HPTLC Methods
Alpinetin is a flavonoidal constituent of seeds of Amomum subulatum Roxb., recently reported to possess vasorelaxant and antiHIV activities. Simple, accurate and precise HPLC and HPTLC methods were developed for the analysis of alpinetin in A. subulatum seed extracts and extraction technique was optimized to get maximum yield using conventional, ultrasonic and matrix solid phase dispersion extr...
