HPTLC and reflectance mode densitometry of anthocyanins in Malva silvestris L.: a comparison with gradient-elution reversed-phase HPLC.
Aqueous alcoholic mallow flower extracts were analyzed both by HPTLC-densitometry in the reflectance mode at 530 nm and by reversed-phase HPLC with gradient elution. For the mallow flowerExpand

Determination of optical purity by nonenantioselective LC using CD detection.
The use of a circular dichroism (CD) based HPLC detection system was recently described by some authors and proposed for a nonenantioselective HPLC enantiomeric purity determination. Indeed theExpand

Human alpha1-glycoprotein acid as chiral selector in the enantioseparation of midodrine and deglymidodrine racemates by HPLC.
Human alpha1-acid glycoprotein (alpha1-AGP) has been used as a chiral stationary phase (CSP) for the enantioseparation of midodrine and deglymidodrine racemates in the same HPLC run. The imobilizedExpand

Analysis of ceftazidime and related compounds by micellar electrokinetic chromatography.
A micellar electrokinetic chromatographic method for the separation and quantification of ceftazidime, its delta2-isomer and pyridine (two ceftazidime related impurities) was developed and validated.Expand

Analysis of venlafaxine by capillary zone electrophoresis.
Capillary electrophoresis has been used for the separation of venlafaxine and two of its impurities deriving from the synthesis process. The electrophoretic experiments were performed usingExpand
