among them 44,96 ± 0,42% are acidic monosaccharides and the rest 55 ± 0,62% are neutral monosaccharides. The considered optimum conditions of hydrolysis by trifluoroacetic acid were: 4 M during 5 hours at 80°C. Anion exchange high performance chromatography of hydrosoluble polysaccharides of Malva leaves indicates the presence of galactose (56.86%), glucuronic acid (20.57%), arabinose (9.04%), rhamnose (8.46%) and mannose (5.05%). The oligosaccharides resulting from the partial hydrolysis of the

stealing. But now , he is clean because for him Ellie is a miracle for his family. Moreover , the birth of Ellie has saved Maria’s life. In fact , Maria didn’t know but she had a cancer. She learned this when she went at the hospital for the chromatography. If she went at the hospital few months later , the doctors could not do anything for her cancer. She says that his daughter saved her life. At the end , Francisco adds that he admires the bravery of his sister and he says that he will always

®ller, prooxidant and photosensitizers was conducted in oven at 60 and 100C for a period of 14 days. Volatile and semivolatile degra- dation products were extracted by solid phase micro extraction (SPME) technique and identi®ed utilizing gas chromatography± mass spectrometry (GC±MS). Chemical and morphological changes were monitored and these are given as carbonyl index, crys- tallinity and melting behavior, molecular weight and molecular weight distribution. The samples containing solely prooxidant

mérite de tenir debout. Elle démontre en tout cas la finesse et la difficulté des phénomènes de surface. 5. Chromatographie ionique sur colonne (HPLC) 5.1. Partie théorique La chromatographie ionique sur colonne (HPLC : High Performance Liquid Chromatography) est un peu l'aboutissement de la chromatographie liquide : en remplaçant la gravité et la pression atmosphérique par de hautes pressions (facilement autour de 100 bars; jusqu'à 450 bars !), elle permet des analyses très fines en des temps remarquablement

en phase inversée. Dans notre cas, l’ion compensateur est l’acide triofluoroacétique (TFA) ; acide ayant à la fois la fonctionnalité d’être une molécule chargée négativement et de molécules hydrophobe. * HPLC (« Hight Performance Liquid Chromatography ») : Le principe de l’ HPLC est de séparer des particules plus fines exigeant des pressions de la phase mobile beaucoup plus élevées.

December 1996; accepted 27 February 1998) This paper summarises some recent work concerned with the development of colour and flavour via the Maillard reaction in both aqueous and restricted moisture model systems. High performance liquid chromatography (HPLC) and capillary electrophoresis (CE), both with diode array detection, are discussed for their ability to separate reaction products. The use of the diode array data to classify reaction products is presented. The coloured reaction products
