The chemical composition, total antioxidant capacity (TAC) and total flavonoids were assessed in fifty-two Andean potato cultivars, with local indigenous names, from Bolivia, comprising five species and one subspecies. Moisture content ranged from 63 to 81%, and on a fresh-weight basis, ash content from 1 to 2%, protein content from 3 to 11%, carbohydrate content from 9 to 35% and total lipids ≤ 0.01%. Solanum stenotomum cultivars showed the highest protein content. The TAC ranged from 1 to 10-μmol Trolox equivalents/g dry matter using Ferric reduction antioxidant power (FRAP) method and from 0.2 to 5 according to the 2,2′-azino-bis (3-ethylbenzithiazoline-6-sulphonic acid) (ABTS) method. The total flavonoids (TF) ranged from 2 to 19, expressed in μmol of catechin equivalents/g dry matter. The Andean potatoes studied appeared to be an important source of antioxidants and polyphenols, as well as proteins. They are therefore important for the diet of the economically depressed indigenous people of the Bolivian Andes. Furthermore, many of these potato cultivars, which still remain unknown outside the Andean region, can be considered superfoods because of their nutritional properties.

在来自玻利维亚的52个以当地土著名字命名的安第斯马铃薯品种中，对化学成分，总抗氧化能力（TAC）和总黄酮含量进行了评估，包括五个物种和一个亚种。水分含量为63％至81％，以鲜重计，灰分含量为1至2％，蛋白质含量为3至11％，碳水化合物含量为9至35％，总脂质≤0.01％。龙葵品种显示出最高的蛋白质含量。使用三价铁抗氧化剂功率（FRAP）方法，TAC的范围为1至10-μmolTrolox当量/克干物质，根据2,2'-叠氮基双（3-乙基苯并噻唑啉-6-磺酸），TAC范围为0.2至5。 （ABTS）方法。总黄酮（TF）范围为2到19，以微摩尔儿茶素当量/克干物质表示。研究的安第斯马铃薯似乎是抗氧化剂，多酚和蛋白质的重要​​来源。因此，它们对于玻利维亚安第斯山脉经济不景气的土著居民的饮食很重要。此外，许多这些马铃薯品种在安第斯地区以外仍不为人所知，由于其营养特性，可被视为超级食品。
