R. Benlarbi et al.: Carboxylic Acids of Pinus pinaster Bark HPLC HPLC analyses were performed with a Jasco chromatograph equipped with a diode 870 UV/VIS detector and 880Up pumps. It is fitted with a 250 * 4.6 mm id, Whatman ODS column that is protected with a pre-column of the same material. The mixture Holzforschung 53 (1999) 580-584
SummaryIn this work, carboxylic acids of the Moroccan Pinus pinaster bark were studied and analysed by High Performance Liquid Chromatography (HPLC), Thin Layer Chromatography (TLC) and Gas Chromatography coupled with Mass Spectrometry (GC-MS). Several acids, such as gallic, p-hydroxyphenylacetic, 3,4-dihydroxyphenylacetic, salicylic, shikimic, protocatechuic, terephtalic, ferulic, p-coumaric, vanillic, caffeic and isovanillic acids, were detected by direct injection of standard products and by studying the mass spectrum of their trimethylsilyl derivatives.
