摘要：

We have studied the efficiency of analytical procedures for two phenolic compounds found in Eucalyptus globulus and Quercus robur L.: gallic and ellagic acid. Isochratic HPLC was used as a mean of quantitative analysis. Eluants for HPLC analysis were H2O:CH3OH:H3PO4 (975,5:19.5:1, v/v/v) for gallic and (449,5:449,5: 1, v/v/v) for ellagic acid. The time required for each HPLC analysis was 10 and 6 min. The recuperation of gallic acid and ellagic acid was respectively 83,0% and 58,6%. We have showed that high temperature Quercus robur L. kiln drying resulted in an important augmentation in gallic and egallic acid proportions.
