BACKGROUND
In this research, water extract solutions of Anemarrhena asphodeloides (AA) rhizomes were added to reconstituted milk at 5%, 10% and 15% (v/v) to prepare AA fermented milk (AAFM5, AAFM10 and AAFM15). The AAFM10 was selected for investigation of hypoglycaemic activity.
RESULTS
Compared with the control fermented milk, titratable acidity values and water-holding capacities of AA fermented milk were increased to different extents, but syneresis values were reduced. The viable counts of Streptococcus thermophilus, Lactobacillus bulgaricus and Bifidobacterium adolescentis were significantly increased, respectively. The blood sugar level of streptozotocin diabetic mice taking AAFM10 was reduced by 14.4%, and the food intake was decreased. The contents of malondialdehyde, blood urea nitrogen, serum creatinine, triglycerides, total cholesterol, and low-density lipoprotein cholesterol were reduced by different degrees, and insulin and total superoxide dismutase were significantly increased.
CONCLUSIONS
AAFM10 had a significant hypoglycaemic effect and improvement in the complications (such as kidney disease and hyperlipemia) in the mouse model of diabetes.
