Abstract

This study was designed to observe the efforts of the feeding Platycodon grandiflorum, Codonopsis ianceolata, perilla oil and safflower oil on the improvement of the lipids in the serum and liver of dietary hypercholes-terolemic rats. Experimental groups mixed with 5% cellulose+10% lard (group 1, control group), 2% cholestyramine+10% lard (group 2), 5% C. Ianceolata+10% perilla oil (group3). 5% P. grandiflorum+10% perilla oil(group 4), 5% C. ianceolata+10% safflower oil(group 5) and 5% P. grandiflorum+10% safflower oil (group 6) were administered to the male rats of the Sprague Dawley for 3 weeks. Concentrations of total cholesterol in serum were significantly lower in the all experimental groups (2~6 groups) than in the control group, and particularly, the lowest in the group 2 and 6. Concentrations of HDL-cholesterol in serum were remarkably higher in the groups 2 and 4. The ratio of HDL-cholesterol to total cholesterol was the highest in the group 2. Atherosclerotic index was lower in the groups 2, 4 and 6. Concentrations of LDL, phospholipid and triglyceride in serum were remarkably lower in the all experimental groups than in the control group, and particularly, lower in the groups 2, 4 and 6. Concentrations of free cholesterol and cholesteryl ester in serum were significantly lower in the all experimental groups than in the control group, and particularly, the lowest in the group 2. Concentrations of glucose in blood were the lowest in the group 2. And groups 3 and 5 were slgnificantly lower. Contents of total cholesterol and triglyceride in liver were significantly lower in the all experimental groups than in the control group, and particularlyr the lowest in the groups 2 and 3. Phospholipid content was showed little differenre among groups but the lowest in the group 2. From the above research, the feeding 5% Platycodon grandiflorum+10% perilla oil and 5% Platycodon grandiflorum+10% safflower oil were effective on the improvement of the lipid compositions in serum and liver.
