Flavonoids are among the most widely distributed natural products in plants with 2000 different compounds occuring in free forms or as glycosides. They have assigned differant roles in nature as signalling molecules. The major and general structures are Flavones, Flavonones, Flavonols, Isoflavones and Anthocyanidin. Methylated, acylated, prenylated or sulfated derivatives can also be met. Flavo...

BACKGROUND Medicinal plants are considered new resources for producing agents that could act as alternatives to antibiotics in the treatment of antibiotic-resistant bacteria. The aim of this study was to evaluate the antibacterial activity of 28 plant extracts and oils against four Gram-negative bacterial species. METHODS Experimental, in vitro, evaluation of the activities of 28 plant extrac...

BACKGROUND AND THE PURPOSE OF THE STUDY Artemisinin is one of the most effective medicine against malaria, which is produced naturally by Artemisia annua in low yield. It is produced in a metabolic pathway, in which several genes and gene products are involved. One of the key genes in this pathway is am1, which encodes amorpha-4, 11-diene synthase (ADS), a key enzyme in artemisinin biosynthesis...

Extensive comparative characterization was performed to explore halophytes native the Persian (Arabian) Gulf. Ten species collected from Western region of Abu Dhabi, United Arab Emirates (UAE) were analyzed for their lignocellulosic components as well ash and extractives content. It found that significantly differ in content carbohydrates, lignin, total ash-free ash. The negatively influence ca...

Degradation of plant patches is considered as one of the indices for rangeland degrading health condition. Investigating the accuracy of triple indices (infiltration, stability and soil nutrient cycle) presented by LFA method seems necessary to determine its efficiency in semi-arid areas with the least cost. This study aims to investigate the role of vegetative species and growing forms on soil...
