Development of novel extraction and separation methods for the determination of anthracyclines and taxanes simultaneously from biological matrices
… and was fully automated. The entire method of extraction, separation and detection was achieved on-line by column-switching between an SPE column and an analytical column. The optimum type of switching valve, extraction conditions and separating conditions were evaluated for both methods in …

An Immobolized Surfactant Extraction Technique Compatible with High Performance Liquid Chromatography-Ultraviolet Visible Detection
Surfactant mediated extractions are analogous to liquid-liquid extractions (LLE) except surfactants are used as extractants instead of organic solvents. The benefit for using surfactants for extractions includes lower toxicity, lower associated costs and direct compatibility with high performance …

Effects of pre and post-harvest treatments on the phenolic compounds and antioxidant activity of different onion varieties
… in onions. The pre-harvest treatments and the novel approach to the post-harvest processing methods (blanching and ultrasound) can serve as ‘recommendations and guidelines’ for the industry or the agriculture authorities at a national level.
