“Lepidum peruvianum Chacón, or Lepidium meyenii Walpers,  internationally well know by its original Andean name, MACA, a tuber of Andine origin still cultivated in the highlands over 12,000 to 15,000 feets over sea level, in Peru for local preparation, was studied. The carbohydrate,  lipid, protein, fiber and also the amino-acid, fatty acid, mineral and sterol fractions were determined. The results show that the tuber is nutritionally interesting. Alkaloid like compounds ( Glucosilanates) were also found. It is concluded that this tuber can be a food source in countries, where economic and technological conditions are inadequate to combat malnutrition.” (1);
