Determination of Some Important Inorganic Elements and Fatty Acids of Medlar’s Fruit from Mazandaran’s Forest

The objective of the present study was determined on the concentration of seven important elementsand chemical composition of the organic compound from medlar’s fruit (iran) using icp-aes and gc-ms techniques. the mineral content of samples was determined by standard addition method and rsds lower than 3.75. the detection limits of the method for the 7 elements were 0.04-4 μglg1. in medlar fruit, the concentration of calcium with compare to k, mg, na, fe, zn and cr was more. fourteen organic compounds of the medlar's fruit were characterized. the results have shown that the main fatty acid is linolelaidic acid with percentages of 24.01. the percentages of oleic acid and palmitic acid in this fruit were 11.45 and 6.97, respectively.
