Background and objectives: The genus Centaurea from the Asteraceae family is one of the most widely distributed plant genera worldwide that has been extensively used in folk medicine for hundreds of years. The present study is the first investigation about the principal constituents of Centaurea albonitens Turrill which is native to Iran. Methods: The aerial parts of C. albonitens were extracte...

Propolis is one of the richest sources of plant phenolics (flavonoids and phenolic acids), which are widely recognized as rather strong antioxidants. The aim of our work was to use colored stable free radical (DPPH* and ABTS*+) spectrophotometric and thin-layer chromatographic (TLC) assays to study the antioxidative behavior of the phenolics (caffeic acid, galangin and pinocembrin) most commonl...

Paulownia tomentosa is a large indecidous tree planted mostly for its fast growing wood and decorative purposes. The tree is also used in traditional Chinese medicine. As a part of our study of natural polyphenols, the fruits of Paulownia tomentosa were extracted by EtOH and than subjected to liquid/liquid extraction. Fractions were analysed by TLC and HPLC to determine presence of phenolic sub...

Microbial pathogens are developing resistance against existing antibiotics, stressing the urgency for discovery of new therapeutic compounds. Actinomycetes, alone produce 70-80% of the available antibiotics. The chances of isolating undiscovered strains from the terrestrial habitats have diminished so that the search for novel products has switched to rare genera of actinomycetes from normal ha...

To prevent microbial growth, chemical solvents are typically utilized. However, hazardous to human health with low antimicrobial effects. Metallic-element (such as copper, silver, and gold) nanoparticles have many applications in biotechnology biomedicine. Copper (CuNPs) efficient owing their antimicrobial, anti-inflammatory, anti-proliferative properties. The objective of this study was perfor...


 Purpose: The present study was done to evaluate the antimycobacterial activity of aqueous and methanol extracts nine plants viz., Buddleja saligna, Carpobrotus dimidiatus, Capparis tomentosa, Dichrostachys cinerea, Ekebergia capensis, Ficus sur, Gunnera perpensa, Leonotis leonurus Tetradenia riparia in South Africa.
 Methods: Aqueous leaves were tested vitro for their against Mycoba...

In Africa, many of the plant resources high nutritional value are not yet included in uses local populations. This study contributes to enhancement lipid potential Musanga cecropioides (R. Brown) seeds. Soxhlet seed oil extraction gave a yield 8.62%. The evaluation physical parameters brings it closer that Argan oil. extracted from seeds M. consists mainly three major fatty acids: ole...

This study was carried out as a prerequisite to evaluate the therapeutic potential of Camellia varieties. The crude extracts of six different plants of green tea Camellia assamica and Camellia sinensis were tested against three Gram-positive and four Gram-negative bacteria using agar disk diffusion method at 50 mg/ml concentration. 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) and dip...
