Prototulbaghia is a genus within the Tulbaghieae in subfamily Allioideae (Amaryllidaceae) and comprises two species restricted to the northeastern escarpment of South Africa. The pollen morphology of these species is studied ...
Synthesis and characterisation of silver nanoparticles using leaf extract of Artemisia afra and their in vitro antimicrobial and antioxidant activities

Elemike, Elias E.; Onwudiwe, Damian C.; Jordaan, Anine; Ekennia, Anthony C. (IET, 2018)

In this study, the conversion of silver ions into ∼30.74 nm sized silver nanoparticles (AgNPs) was achieved in 30 min at a reaction temperature of 80–90°C in aqueous leaf extract of Artemisia afra. The synthesised AgNPs ...
