Abstract

Macro- and micro-elements of Jerusalem artichoke (Helianthus tuberosus L.) tubers growing in Konya (Karapınar and Çumra locations) provinces in Turkey were determined by inductively coupled plasma atomic emission spectrometry (ICP-AES). Potassium, phosphorus, magnesium, and calcium contents of Jerusalem artichoke were found at high levels, whereas K content was found as 21615 mg/kg and 26251 mg/kg for Jerusalem artichoke; P contents of Jerusalem artichoke were found between 2585 and 4791 mg/kg; and Ca was determined between 1573 and 2073 mg/kg for Jerusalem artichoke. In addition, Zn content was found in a range from 11.0 mg/kg for Yaylapınar to 15.6 mg/kg for Saracoğlu artichoke. While Fe content of Jerusalem artichoke was found between 23.32 mg/kg to 54.46 mg/kg, Cu content of Jerusalem artichoke was determined between 4.50 mg/kg to 8.98 mg/kg. The Cr contents of Jerusalem artichoke were found between 0.396 mg/kg to 0.642 mg/kg. Ash contents of Jerusalem artichoke tubers were found between 5.70% to 7.63%. Protein contents of Jerusalem artichoke samples were found between 6.23% to 10.71%.
