Blood profiles
The initial mean postprandial serum TG concentration in the
high fructose control diet-fed rats before GTE or MGTE treatment
was 219.8 ± 77.5 mg/dL. Fig. 1 illustrates the changes in
postprandial serum TG levels over a 4-week period of high
fructose diet and high fructose diet with GTE or MGTE
treatment. Fructose-fed rats had a higher serum TG level (P <
0.05) than normal control diet-fed rats and it remained elevated
for the remainder of the 4-week experimental period. The
administration of GTE or MGTE in high fructose-fed rats reduced
postprandial blood TG significantly (P < 0.05). However, there
was no significant difference in the postprandial blood TG
responses to the GTE or MGTE treatment.
Table 2 summarizes the effect of GTE and MGTE treatment
on fasting serum TC, HDL-C, NEFA, and uric acid concentrations.
High fructose-fed rats had higher fasting serum TC levels
(P < 0.05) than normal control diet-fed rats. GTE and MGTE
administration in high fructose-fed rats decreased TC levels over
the 4-week treatment period. However, there was no significant
difference between the GTE and MGTE treated groups.
