Abstract

The chemical composition of the seed oil and residual seed meal of Rosa rubiginosa L. (<<rosa mosqueta>>) harvested at El Bolson (Chubut, Argentina) was analyzed. Iodine Number of the drying oil is 172,7, having high content of linolenic acid (31,4% of total acids). Sitosterol is the main component of the sterol fraction. Residual seed meal is rich in crude fiber (56,6%) and polysaccarides (18,4%) and poor in proteins (9,75%), which ha ve low reactive lysine content.
