摘要:The effect of dietary safflower phospholipid (Saf-PL) and soybean phospholipid (Soy-PL) on plasma, lipid, and fecal lipids in rats fed a cholesterol-free diet was compared with that of a triglyceride mixture (control). The triglyceride mixture (SP-Oil) of safflower oil and palm oil (8:2) contained almost comparable amounts of linoleic acid to safflower phospholipid or soybean phospholipid. Concentrations of total cholesterol in plasma of rats fed the Saf-PL and Soy-PL diets were significantly decreased in comparison with that of the SP-Oil diet. Saf-PL induced a reduction in the concentration of liver cholesterol compared with SP-Oil. Soy-PL tended to reduce the liver cholesterol. The proportions of total cholesterol in all lipoprotein fractions were similar among the groups. The activity of plasma lecithin-cholesterol acyltransferase was increased in rats fed the phospholipid diets; Saf-PL indicated the highest value. Saf-PL and Soy-PL caused an enhanced excretion of not only neutral steroids but also acidic steroids into feces compared with SP-Oil. These results suggest that, in addition to soybean phospholipid, safflower phospholipid decreases plasma and liver cholesterol in rats fed a cholesterol-free diet and safflower phospholipid causes a favorable alteration in plasma and liver lipids compared with soybean phospholipid.
