Carbon dots of small carbon nanoparticles surface-functionalized with 2,2'-(ethylenedioxy)bis(ethylamine) (EDA) were synthesized, and the as-synthesized sample was separated on an aqueous gel column to obtain fractions of the EDA-carbon dots with different fluorescence quantum yields. As already discussed in the literature, the variations in fluorescence performance among the fractions were att...
Ferulago species have been utilized since ancient times as digestive, sedative, aphrodisiac, along with in salads or as a spice due to their special odors. The study reports isolation and characterization of bioactive compounds of Ferulago pachyloba (F. pachyloba), Ferulago trachycarpa (F. trachycarpa), Ferulago bracteata (F. bracteata), and Feru...

The current research was carried out to assess the antibacterial activities and phytochemical analysis of the methanol, n-hexane, ethyl acetate, n-butanol soluble fractions and aqueous extracts of the tubers of Arisaema jacquemontii. All the extracts were tested for their antibacterial potential at 1, 2 and 3 mg disc-1 concentrations against 6 bacterial strains through disc diffusion suseptibil...
The aim of this study was to analyze and evaluate antimicrobial potential of medicinal plants obtained from kacha area of river indus, that are used as ingredients of traditional medicine for treatment of multiple infectious diseases. The antimicrobial activities of methanol and aqueous extracts of 5 medicinal plants of a traditional medicine were evaluated against 6 human gram positive (Staphy...

Ward Taifi (Taif rose) is considered one of the most important economic products of Taif, Saudi Arabia. In this study both fresh and dry Taif rose were biologically and phytochemically investigated. The 80% methanol extracts and n-butanol fractions of dry and fresh Taif rose had high radical scavenging activity toward artificial 1,1-diphenyl picrylhydrazyl (DPPH)(•) radical with SC50 values ran...
Moringa oleifera Lam. (M. oleifera) from the monogeneric family Moringaceae is found in tropical and subtropical countries. The present study was aimed at exploring the in vitro wound healing potential of M. oleifera and identification of active compounds that may be responsible for its wound healing action. The study included cell viability, proliferation, and wound scratch test assays. Differ...

Benthic marine invertebrates collected from sub-Arctic regions of northern Norway, were found to be a promising source of novel bioactive compounds against human and fish pathogenic bacteria and fungi. Lyophilized material from seven species of ascidians, six sponges and one soft alcyonid coral were extracted with 60% acidified acetonitrile (ACN). After separation into an ACN-rich phase (ACN-ex...

Hippocratea africana root used locally in the treatment of poisoning was investigated to confirm its antidotal potential rats. The extract (200-600 mg/kg) and fractions; dichloromethane (DCM) aqueous, 400 were evaluated for nephroprotective activity against doxorubicin-induced kidney injury Kidney function parameters, oxidative stress markers histology assess protective effect extract. fraction...
Introduction: Neisseria gonorrhoeae is a sexually transmitted bacterial pathogen for which there is an increasing antimicrobial resistance concern. Frequency of isolation of multi drug resistant strains is increasing rendering a potential 'Super bug' status for N. gonorrhoeae. Material & methods: Agar dilution method was used to evaluate in vitro anti N. gonorrhoeae activity of crude and solven...
