example 1
[0084] As examples of the effects of a compound including the chemical formulas II, stevioside was tested on normal Wistar rats and on GK rats. 2.0 g glucose / kg body weight and 0.2 g stevioside / kg body weight were dissolved in 0.9% saline and infused intravenously. The plasma glucose and insulin levels were measured over a period of 2 hours.
[0085] The results are shown in FIGS. 2a, 2b, 3a and 3b, were the O-O series (n=6 for Wistar and n=14 for GK) illustrate glucose infused alone and the ②-② series (n=6 for Wistar and n=12 for GK) illustrate the combined glucose and stevioside infusion. Data are given as mean ±SEM.
[0086] After administration of the glucose load, plasma glucose raised immediately and plasma insulin raised abruptly. When stevioside was added together with the glucose, a diminished glucose response was found in the GK-rat and a significant decrease was observed already after 30 min. In the GK rat, stevioside caused a pronounced increase in the insulin response compa...

[0088] Islet from 6-10 NMRI mice were isolated and incubated in the presence of 16.7 mmol / l and 10−9-10−3 mol / l stevioside or 10−9-10−3 mol / l steviol.
[0089] The results of these tests are illustrated in FIGS. 4a and 4b where each column represents mean ±SEM from 24 incubations of single islets. Black bars in FIG. 4a indicate that stevioside is present and hatched bars indicate that stevioside is absent.
[0090] Black bars in FIG. 4b indicate that steviol is present and hatched bars indicate that steviol is absent.
[0091] The figures show that stevioside and steviol are capable of potentiating glucose-stimulated insulin secretion. Further tests confirmed that a stimulatory effect was found already at a very low concentration (above 0.1 nM).
example 3
[0092] During a glucose tolerance test, an intravenous bolus of stevioside of 0.2 g / kg body weight was injected in GK rats (the ②-② series (n=6)). GK rats receiving 0.9% saline intravenously served as controls (the O-O series (n=6)). Glucose 2.0 g / kg body weight was administered as a bolus at timepoint 0 min. The plasma glucagon responses are shown as mean ±SEM in FIGS. 5a (control) and 5b (GK). The plasma glucagon was suppressed in the stevioside treated GK rat.
