The operational conditions of the protein extraction step from a grass (pennisetum purpureum schum) were studied. Extracting agents utilized were water and alkaline solutions. The best extraction conditions observed in the present was the extraction at 40ºC and pH 10. Similar extraction yield was obtained with water as extracting agent in a two step process at 70ºC. It was studied also the dry mass and protein content in the plant with the cutting period.
