The percent composition, soluble and insoluble food fibers, oil fatty acids and minerals were determined in the mesocarp of fruits of three peach palm (Bactris gasipaes Kunth) populations grown in Central Amazonia, Brazil. Amino acids were also determined in one of the populations. The mean protein levels ranged from 1.8 to 2.7%, lipid levels ranged from 3.5 to 11.1%, the nitrogen free fraction ranged from 24.3 to 35%, food fiber ranged from 5.2% to 8.7%, and energy ranged from 179.1 to 207.4 kcal%. All essential, as well as non-essential, amino acids were present, with tryptophan and methionine presenting the lowest mean concentrations. The mono-unsaturated oleic acid predominated in the oil, ranging from 42.8 to 60.8%, and palmitic acid was the most abundant saturated fatty acid, ranging from 24.1 to 42.3%. Among the essential fatty acids, linoleic acid was the most abundant, with a maximum of 5.4% in Pampa-8. The most important mineral elements were potassium, selenium and chromium, respectively corresponding to 12%, 9% and 9% of daily recommended allowances. Considering the nutritional potential of the fruit, we suggest its more frequent incorporation into the diet of the Amazonian population.
对生长在巴西亚马孙中部地区的三个桃棕（Bactris gasipaes Kunth）种群果实的中果皮进行了成分分析，测定了其可溶和不可溶膳食纤维、油脂脂肪酸及矿物质含量。还对其中一个种群的果实进行了氨基酸测定。结果显示，蛋白质平均含量在1.8%至2.7%之间，脂质含量在3.5%至11.1%之间，无氮成分含量在24.3%至35%之间，膳食纤维含量在5.2%至8.7%之间，能量含量在179.1至207.4千卡%之间。所有必需氨基酸和非必需氨基酸均有检出，其中色氨酸和蛋氨酸的平均浓度最低。油脂中以单不饱和油酸为主，含量在42.8%至60.8%之间，棕榈酸是含量最高的饱和脂肪酸，含量在24.1%至42.3%之间。在必需脂肪酸中，亚油酸含量最高，在潘帕-8种群中最高可达5.4%。最重要的矿物质元素是钾、硒和铬，分别占每日推荐摄入量的12%、9%和9%。考虑到该果实的营养潜力，建议亚马逊地区居民在日常饮食中更频繁地食用。
