Antimicrobial, immunomodulatory and cytotoxic activities of green synthesized nanoparticles from Acacia honey and Calotropis procera

Calotropis procera and Somra (Acacia) honey are used in traditional medicine. The benefits of mixing 20% Somra honey and C. procera leaf water extract (CPLWExt) were aimed to be studied. Honey/CPLWExt were utilized to produce silver nanoparticles (AgNPs) separately. AgNPs were characterized via UV/Vis and electron microscope scanning. Bio-molecules in CPLWExt/honey were investigated utilizing FT-IR spectroscopy. Biological activities of CPLWExt and honey were tested. The outcomes showed that CPLWExt and honey have numerous functional groups and could produce AgNPs. CPLWExt, CPLWExt + AgNPs, honey and honey + AgNPs hindered the growth of rat splenocytes, while CPLWExt + honey invigorated it. Antimicrobial power was found in CPLWExt and honey, which increased in the presence of AgNPs. Honey/honey + AgNPs suppressed the proliferation of HeLa and HepG2 cells. In conclusion, honey/CPLWExt could produce AgNPs and showed immunomodulatory and antibacterial power. Somra honey/honey + AgNPs have anticancer power. Somra honey + CPLWExt reflected a good immunostimulatory powers that can be nominated as an immunostimulant. (c) 2021 The Author(s). Published by Elsevier B.V. on behalf of King Saud University.
