The study of ethanol extract of Epilobium angustifolium L. on blood sugar level in type II diabetic rats.

Epilobium angustifolium (EA) is well known as a traditional medicinal plant in many countries with multiple health effects. However, the chemical composition and anti-diabetic effect of EA has not been reported. In our study, the composition and anti-diabetic effects of ethanol extracts from EA in vivo and in streptozotocin (STZ)-induced type II diabetic rats were investigated. EA ethanol extracts exhibited protection effect on H2O2 induced oxidative stress damage INS-1 cells, reduce the body weight loss, blood glucose level and increase insulin level when compared with those of diabetic rats. Following 21 days of EA treatment at 9.2 and 18.4mg/kg, BW increased by 15.85% and 15.53%, respectively, which were extremely higher than diabetic group (9.50%). The fasting blood glucose level of EA 9.2mg/kg group rats significantly decreased by 60.43% and insulin level increased by 2.78 times, respectively. Corresponding to that, the fasting blood glucose level of EA 18.4mg/kg group rats decreased by 52.61% and insulin level increased by 2 times, respectively. Collectively our data suggest that ethanol extract of EA has remarkably hypoglycemic effect in type 2 diabetes and EA might be a promising functional food or medicine for T2DM treatment.

Production technology, nutritional, and microbiological investigation of traditionally fermented mare milk (Chigee) from Xilin Gol in China.

Mare milk originated from female horses, known as mares, to feed their foals during lactation. The health-promoting characteristics of traditionally fermented mare milk (Chigee) are well known for the function of clinic treatment in the traditional Mongolian medicine. This study was conducted to investigate the production technology of Chigee and to evaluate the nutritional and microbiological characteristics of mare milk and Chigee based on 188 samples. The nutritional analysis of mare milk and Chigee indicated that lactose significantly decreased from 6.95 ± 0.45% to 2.82 ± 1.65% and acidity and alcoholic content significantly increased to 136.72 ± 57.88°T and 1.22 ± 0.7%, respectively, after spontaneous fermentation of mare milk. The microbiological analysis of Chigee showed that the total lactic acid bacteria (LAB) count varied from 5.32 to 8.56 log cfu/ml and total yeast count varied from 2.41 to 6.98 log cfu/ml. Moreover, the acidity of Chigee rose with the increase in LAB count within limits, and high acidity (≥178°T) inhibited the growth of coliforms. These findings provide an understanding of traditional production technology, nutrition, and microbiology that is fundamental for establishing the food standard of Chigee in China and will contribute to standardize the fermentation process for the industrial production of Chigee in the future.
