The aim of this study was to determine a reliable procedure for the quantification of organic acids, alcohol soluble sugars and sugar alcohols in fruit flesh by means of a rapid GLC method, without resorting to methoximation of sugars and employing apricot as a model. The use of two internal standards, an accurate derivatization and a proper calibration of the GLC conditions allowed an accurate quantitative analysis of the compounds detected in the unknown samples. This simple procedure improves the speed of preparation of the trimethylsilyl derivatives and is highly reproducible. Variability was found between years for each of the five cultivars studied and for each compound in terms of absolute values, whereas the percentage incidence of the single sugars as a total was more stable over the two years of observation.
