The dye mixtures formed from three commercial hair colour formers were purified by absorption onto human hair wefts, washed and dried, extracted with dichloromethane:trifluoroacetic acid (75:25) and then analysed by liquid chromatography–mass spectrometry. Only 1–2 dyes were identified from each complex mixture of commercial aromatic amines along with a broad UV absorption mainly consisting of mixtures of quaternary ammonium salts from shampoos and some surfactants. Mecetronium ethyl sulfate and didecyldimethylammonium chloride were the main ammonium salts.

Objective: The study was carried out with an objective to characterize the possible bioactive phytochemical constituents from fruits of Schisandra chinensis Bail. by liquid chromatography–mass spectrometry analysis.Methods: Plant material was collected from Schisandra chinensis during August–October. The dried plant fruits were extracted with solvents using ethanol 95% extractor. The results of chromatography–MS analysis performed on the instrument Agilent Technologies established the presence of major and minor components. It was conducted a qualitative and quantitative comparison of infusions using software ChemStationE 02.00 and full library of mass spectra NIST 05.
