Abstract:

The experimemt observed effect of flaxseed on Wistar rats′ serum triglyceride(TG), total cholesterol(TC), high density lipoprotein cholesterol(HDL-C), low density lipoprotein cholesterol(LDL-C), Apo B and atherosclerosis index(AI). The rats were divided into a lard group, three flaxseed groups(low, middle and high level)and a basal diet group. Thirty two days later, significant decrease in serum TC and LDL-C were found in the flaxseed groups(low, middle and high level)as compared with the lard group(P<0.05), significant decrease in serum TG and significant increase in serum Apo B, HDL-C/TC and AI were found in the flaxseed groups(middle and high level)as compared with the lard group(P<0.05), but there was no difference in HDL-C between flaxseed group and lard group(P>0.05). The experiment indicates that flaxseed rich in α linolenic acid can be used to prevent and lower blood lipid, and deserves further study and development.

Key words: flaxseed, blood lipid, &alpha, -linolenic
