Separation and identification of phospholipids from fresh, cold and frozen bolti fish (Tilapia Orhyochromis)‎ formed in Riyadh area and the effect of antibiotics on them

Abstract EN

The phospholipids content of Bolii fish ( Tilt/pia orhyochromis i obtained from artifi"iallake in Riyadh was determined over periods of storage at (4"(') and ( ~ IW{') .
