Key Findings:
Flaxseed and date palm (Phoenix dactylifera) leave extract were studied for effects on serum concentration of glucose and lipids in alloxan diabetic rats. Flaxseed extract produced a significant decrease in serum glucose levels and reduced TC significantly by 37 and 55% after 2 and 4 weeks of treatments. LDL-C was significantly reduced 21% and 29% respectively, with either flaxseed or date palm. The hypoglycemic effects of flaxseed could be due to seciosolariciresinol diglucoside (SDG).
ABSTRACT:
The aim of the present investigation was to examine the effect of flax seeds (FS) and Date Palm Leaves (DPL) extracts on the concentration of serum glucose and lipids in alloxan diabetic rats. Rats were divided into six groups, normal control rats (without treatment with either FS or DPL), normal control rats treated with either FS or DPL extract for four weeks, diabetic control rats and diabetic rats treated with either FS of DPL extract for four weeks. The concentration of glucose in diabetic rats treated with FS (D+FS) for four weeks was significantly decreased from 17.20±2.33 to 8.14±0.54 mmol L-1 (p<0.001). Serum total cholesterol concentration (TC) of diabetic rats treated with either FS or DPL extract showed significant decrease by 40 and 31% respectively in four weeks. Also, serum low density lipoprotein cholesterol (LDL-C) concentration was significantly decreased after two weeks of treatment (p<0.001 and p<0.01, respectively). However, no significant changes were obtained in serum high density lipoprotein cholesterol (HDL-C) concentration. Results of the present study showed that FS extract has a hypoglycaemic effect against alloxan diabetic rats. Present findings also showed that treatment of alloxan diabetic rats with either Fs or DPL extract significantly decreased serum concentration of TC and LDL-C. Present findings suggest that both of FS and DPL extracts could have a protective effect against diabetes complications as well as against hyperlipidemia through improvement of lipid profile.
