Selected phenotypes of dried maca () hypocotyls and supercritical CO extract (USPlus) of saw palmetto () were used to determine their targeted, cytotoxic action in prostate cancer cells. Fingerprinting by HPLC-MS and PCA analysis showed compositional differences in glucosinolates, amides, macamides, and other alkaloids, which varied based on the color and the size of hypocotyls. These phytochemical differences translated into a higher antioxidant potential of red maca than black maca samples.
