Investigation of bioactive compounds in leaf and anticancer activity of its biosynthesized gold nanoparticles.

The development of cancer therapies has become difficult due to high metastasis, and lack of tissue selectivity, which in most cases affects normal cells. Demand for anticancer therapy is therefore increasing on daily basis. Gold nanoparticles (AuNPs) have many applications in biomedical field.

Biological synthesis of gold and silver nanoparticles using leaf extracts of and their comparative antioxidant activities.

The use of plant and plant products in the synthesis of silver nanoparticles (AgNPs) and gold nanoparticles (AuNPs) is made possible because of the natural inherent phytochemicals responsible for the reduction of respective metallic salts to nanoparticle forms, and ensuring therapeutic applicability. In this study, synthesis of AgNPs and AuNPs was performed using two different aqueous extraction methods for : maceration using laboratory method of extraction (cold aqueous extract of (AECR)), and decoction using traditional healer's method of extraction (hot aqueous crude extract of (CECR)). The synthesized nanoparticles were characterized using various methods, and antioxidant potential were thereafter investigated.
