Abstract: The technical coditions on the supercritical fluid extraction(SFE) of Linolenic acid oil From were studied, including pressure and temperature of extraction, temperature of rectifying column and extracting time .Though orthogonal experimens,the optimal extracting condition was got .Compared with the method of seqeezing ,the extracting rate is higher and the active component are better conserved by supercritical fluid extraction(SFE).

Key words: supercritical fluid extraction(SFE), pinenutlet L, inolenic acid oil
