Objectives: Belonging to Papaveraceae family, Glaucium vitellinum is one of the Persian endemic plants which has not been investigated biologically. The present paper focused on the assessment of the antibacterial and antifungal activities of the total methanol extract and alkaloid sub-fraction of the flowering aerial parts of G. vitellinum. Materials and Methods: The antibacterial and antifung...

Nepeta depauperata belongs to the Lamiaceae family and is one the Persian endemic plants which has not been investigated biologically. In the present paper we had focused on the assessment of the antibacterial and antifungal activities of the total methanolic extract and different sub-fraction of the flowering aerial parts of it. The Antibacterial and antifungal activities were investi...

Background & Aim:Belongs to Rosaecea family, Rosa foetida is one the Persian native plants which has not been investigated biologically. As it is traditionally used topically as poultice to treat infectious skin burns, the present paper focused on the assessment of the antibacterial activities of different extracts of R. foetida flowers against the main cause of skin burn woun...

A number of chalcones were synthesized by reacting indole-3-aldehyde, prepared by Vilsemeir Haack reaction with 4-substituted acetophenone in NaOH solution in ethanol. These chalcones were immediately reacted with urea, thiourea and guanidine hydrochloride in presence of concentrated hydrochloric acid as reagent to obtain the corresponding hydroxy, thio and amino pyrimidines. The synthesized he...

abstract background: premature neonates’ feeding is of great importance due to its effective role in their growth. these neonates should reach an independent oral nutrition stage before being discharged from the neonatal intensive care unit. therefore, the researcher decided to conduct a study on the effect of palady and cup feeding on premature neonates’ weight gain and their reaching full ora...

existence of cracks in industrial structures is one of the important causes of their failure, especially when they are subjected to important axial compressive forces that might lead to buckling. therefore, it must be considered in stress analysis and designing and loading of such structures. in this paper, the buckling and post-buckling behaviors of stainless-steel cracked plates under axial c...

In the present study the bark of Plumeria alba Linn. (Apocynaceae) was evaluated for pharmacognostical and phytochemical parameters and methanolic extract for antimicrobial activity by determining its MIC (by checker board method) and zone of inhibition (by cup plate method).Pharmacognostical parameters of the bark of Plumeria alba Linn. (Apocynaceae) were studied with the aim of drawing the ph...

A green chemistry approach for organic synthesis is described here, which involves microwave exposure of reactants in presence or absence of solvents. A novel and simple method has been developed for the synthesis of some benzotriazole derivatives under microwave irradiation. In addition, these compounds were synthesised also by conventional heating procedures for comparison. All the compounds ...
