To provide a method for producing a Maca extract, capable of efficiently extracting the Maca extract containing a benzyl glucosinolate from Maca (Lepidium meyenii).
This method for producing the Maca extract comprises extracting an extract liquid from the Maca by water or a water-containing alcohol. The extract liquid is passed through a high porous-type synthetic polymer adsorption resin. The Maca extract containing the benzyl glucosinolate is obtained from an adsorption fraction which is adsorbed on the high porous-type synthetic polymer adsorption resin. It is preferable that the Maca extract is obtained by passing the extract liquid through the high porous-type synthetic polymer adsorption resin, after removing insoluble matter from the extract liquid extracted from the Maca and then concentrating the liquid. A concentration of the benzyl glucosinolate is made to be more higher, while the insoluble matter is removed from the Maca extract.
