Abstract: The nutritional components in bamboo shoots of Phyllostachys aurea Carr. ex A. et C. Riv. of 3 different geographical provenance from China and the US were analyzed and compared; Nutrition and edible value of bamboo shoots has been analyzed in order to provide a theoretical basis for development and utilization of P. aurea. The results shows that the water content has little difference among different provenance; The content from high to low is Nanjing(90.63%), Kunming (89.92%) and Pineville (88.69%); Total sugar content in provenance of Kunming is the highest (46.93%), while in the US is the lowest(17.54%); The descending order of advantage object for crude protein and crude fat is Nanjing>Kunming>Pineville. Crude fiber has little difference between the provenances of Kunming and Nanjing; and Pineville has slight advantage(9.78%). K content is the most abundant in the detection of mineral elements. K content in provenance of Pineville is twice as much as Kunming and Nanjing, microelements shows the variation trend of Pineville>Nanjing>Kunming. The total amino acids in provenance of Nanjing and Pineville shows a clear significant advantage in detected content of 17 kinds of amino acids; Methionine and cystine are their first limiting amino acids. The essential amino acid content of Kunming provenance is also lower than the others; And its first limiting amino acid is threonine.
