Vaccinium Extracts as Modulators in Experimental Type 1 Diabetes.

Antihyperglycemic effects of four extracts obtained from leaves and fruits of Vaccinium myrtillus and Vaccinium corymbosum were assessed in diabetic rats. In addition, the effects of extracts on diabetic-related complications such as the development of diabetic cataract and oxidative stress were evaluated. Type 1 diabetes was induced with a single dose of streptozotocin in Wistar rats.

Isolation and quantitative analysis of physalin D in the fruit and calyx of Physalis alkekengi L.

Physalin D was isolated from the methanol extract of Physalis alkekengi L. fruits by combination of different chromatographic methods (CPC, TLC, HPLC). The structure was elucidated based on H and C NMR spectral analysis with the aid of 2D-correlation spectroscopy (H, H-COSY, HSQC and HMBC) and comparison with literature data.
