Figure 1: Blood glucose concentrations in control and diabetic rats, treated or not with extracts from leaf, root and seed of Zyziphus lotus L. for 3 weeks. The rats were rendered diabetic and given or not different extracts (leaf, root or seed) of Z. lotus L. as described in the Materials and Methods section. Each value represents the mean ± SEM (n=6). Asterisks show the significant differences (p<0.001) as compared to diabetic animals on the respective days.
