This study was conducted to analyze the nutritional components of the purple yam planted in Shaoyang and Zhuzhou, Hunan.The results show that the nutritional components of the two regions' purple yam were rich, especially its protein content was higher, and Shaoyang's purple yam protein content was 9.99% and Zhuzhou's was 15.91%. The two areas' purple yam was rich in amino acids and its amino acid contents were 62.54 g/kg and 101.05 g/kg, respectively. Its microelement content was rich, such as Fe, Zn, Mn and Se, they were 20.81 mg/kg, 16.04 mg/kg, 7.14 mg/kg and 26.40 mg/kg in Shaoyang's purple yam, and 27.65 mg/kg, 19.19 mg/kg, 2.03 mg/kg and19.70 mg/kg in Zhuzhou's purple yam, respectively.
