Selective solid-phase extraction of artificial chemicals from milk samples using multiple-template surface molecularly imprinted polymers.

The MTMIP served as a simple and effective pretreatment method and could be successfully applied to the simultaneous analysis of multiple target components in complex samples and may find useful applications as a solid-phase absorbent in the simultaneous determination of trace quinolones and estrogens in milk samples.

Study on the PEG-based microwave-assisted extraction of flavonoid compounds from persimmon leaves.

PEG-based MAE represents an efficient choice for the extraction of bioactive substances from traditional Chinese medicines for flavonoid compounds from persimmon leaves by having higher efficiency than ethanol-based and PEG- based ultrasonic-assisted extractions.

Preparation of chitosan/silk fibroin/hydroxyapatite porous scaffold and its characteristics in comparison to bi-component scaffolds.

The in vitro biocompatibility with osteoblast-like MG-63 cells showed that all the scaffolds are suitable for cell attachment and proliferation; however, the CS/SF/nHA composite porous scaffold is much more effective than the others.

Microwave-assisted one-step extraction-derivatization for rapid analysis of fatty acids profile in herbal medicine by gas chromatography-mass spectrometry.

The MAED method simplified the sample preparation procedure, shortened the reaction time, but improved the extraction and derivatization efficiency of lipids and reduced ingredient losses, especially for the oxidization and isomerization of unsaturated fatty acids.

Preparation of 17β-estradiol surface molecularly imprinted polymers and their application to the analysis of biological samples.

Compared with traditional C18 SPE agents, the particles showed high selectivity and extraction efficiency for E2 in the pretreatment process, and could therefore be used to determine trace estrogen in biological samples with a UV detector only.
