Biosynthesis of Clinacanthus nutans Lindau leaf extract mediated ag NPs, au NPs and their comparative strong muscle relaxant, analgesic activities for pain management in nursing care for using in intensive nursing care unit

摘要

The present work showed the preparation of gold (Au NPs) and silver nanoparticles (Ag NPs) using aqueous leaf extract of Clinacanthus nutans Lindau (C. Lindau). The prepared NPs were studied using various microscopic and spectroscopic techniques, which confirmed the formation of crystalline Ag NPs, Au NPs that are stabilized with C. Lindau extract polyphenols. The prepared Au NPs and Ag NPs are studied to assess their comparative analgesic and muscle relaxant activities conducted on BALB/c mice. The muscle relaxant studies displayed that Ag NPs were comparatively higher efficient than Au NPs and methanolic C. Lindau extract in traction examination. Additionally, the analgesic studies exhibited that Ag NPs, Au NPs showed maximum percentage reduction in acetic acid induced writhing at the concentrations of 50, 100 and 150 mg/kg body weight. Further, these results conclude that as prepared Au NPs and Ag NPs prepared from C. Lindau leaf extract demonstrated very good analgesic and muscle relaxant activities for the use of pain management in nursing care.
