In order to estimate the chemical composition of Raspberry (IR Crataegifalius), the free amino acids were analyzed by amino acid autoanalyzer, and organic acids contents were determined by gas chromatography and the free sugars were detected by paper chromatography. The results obtained were as follows: 1) The free amino acids found in Raspberry were 18 kinds of them, especially, all essential amino acids were showed, and lysine was abundant among them, consequently it was found that the composition of amino acids in Raspberry is more superior than those of the other fruits. 2) The organic acids in Raspberry were found citric acid, tartaric acid, malic acid and fumaric acid. It was found that the quantity of the organic acids was less than those of other common fruits. 3) Sugar such as glucose, fructose, maltose and mannose were detected by paper chromatography.
