Webthe residue must be re-dissolved in water before analysis with HPLC or LC/MS. The purpose of this research is to develop a simple, fast, accurate and sensitive method for glycol analysis using GC/FID. This developed method is applicable to drinking water, waste water, as well as to ISS humidity condensates and biological samples, such as urine. II. WebAbstract: Luteolin (Lu) is one of the flavonoids with anticancer activity, but its poor water solubility limits its use clinically. In this work, we used monomethoxy poly (ethylene glycol)-poly (ε-caprolactone) (MPEG-PCL) micelles to encapsulate Lu by a self-assembly method, creating a water-soluble Lu/MPEG-PCL micelle.
