Abstract: In this study, antimicrobial effect of Greek clover was determined with usage of MIC (minimum inhibition concentration) and agar diffusion method. Moreover, pH, water activity and microbial change were determined during storage of fenugreek paste. At first part of our study, microbial load of spices was evaluated. Two different fenugreek pastes were produced with mixing of Greek clover, spices, garlic and water. Fenugreek pastes were stored at 4 °C. At the second part, antimicrobial effect of Greek clover was determined on Escherichia coli, Staphylococcus aureus, Bacillus subtilis, Debaryomyces hansenii, Aspergillus parasiticus, Candida rugosa, Mucor spp., when the concentrations of Greek clover were 8%, 12% and 16%. According to the results obtained, mould growth was determined at 15th and 30th days of storage in first and second fenugreek samples, respectively. Greek clover showed only antifungal effect on Aspergillus parasiticus at previously mentioned concentrations.
Abstract: This study was conducted to evaluate the anti-diabetic
properties of ethanolic extract of two plants commonly used in folk
medicine, Mormodica charantia (bitter melon) and Trigonella
foenum-graecum (fenugreek). The study was performed on STZinduced
diabetic rats (DM type-I). Plant extracts of these two plants
were given to STZ diabetic rats at the concentration of 500 mg/kg
body weight ,50 mg/kg body weight respectively. Cidophage®
(metformin HCl) were administered to another group to support the
results at a dose of 500 mg/kg body weight, the ethanolic extracts and
Cidophage administered orally once a day for four weeks using a
stomach tube and; serum samples were obtained for biochemical
analysis. The extracts caused significant decreases in glucose levels
compared with diabetic control rats. Insulin secretions were increased
after 4 weeks of treatment with Cidophage® compared with the
control non-diabetic rats. Levels of AST and ALT liver enzymes were
normalized by all treatments. Decreases in liver cholesterol,
triglycerides, and LDL in diabetic rats were observed with all
treatments. HDL levels were increased by the treatments in the
following order: bitter melon, Cidophage®, and fenugreek. Creatinine
levels were reduced by all treatments. Serum nitric oxide and
malonaldehyde levels were reduced by all extracts. GSH levels were
increased by all extracts. Extravasation as measured by the Evans
Blue test increased significantly in STZ-induced diabetic animals.
This effect was reversed by ethanolic extracts of bitter melon or
fenugreek.
