detection of volatile compounds of medicinal plants with some nano-sorbents using modified or new methodologies and investigation of antioxidant activity of their methanolic extracts
in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...
Measurement of amylase activity.
The Nelson photoelectric method for the determination of glucose in biological fluids (1) has proved to be the method of choice in this laboratory and in many others, owing to its reproducibility, stability of color, and excellent agreement with the Beer-Lambert law. Nelson, however, states that the method is unsuitable for the determination of diastatic activity. Since it is convenient and eco...

متن کاملAmylase inhibitory activity of some macrolichens in Mazandaran province, Iran
Introduction: α-amylase is a major form of amylase found in humans and other mammals. It is the special key enzyme involved in carbohydrates breakdown. Inhibition of this enzyme could be used in treatment of diabetes. In this study, the effect of ten Iranian macrolichens on alpha amylase were tested. Methods: Different concentrations of the extracts (25, 50 and 75 mg/ml) were incubated wi...
متن کاملInhibitory Effects of Six Allium Species on ?-Amylase Enzyme Activity
Diabetes mellitus is a metabolic disorder characterized by chronic hyperglycemia. The management of the blood glucose level is a critical strategy in the control of diabetes complications. Inhibitors of carbohydrate hydrolyzing enzymes have been useful as oral hypoglycemic drugs for the control of hyperglycemia especially in patients with type II disables mellitus. The goal of the present study...
