Abstract

The plant Brugmansia suaveolens (Bercht. & Presl) belongs to the family Solanaceae and is endemic to the Malnad region (Shimoga) of the Western Ghats. Traditionally leaf extract has been applied externally to treat cut wounds, pain-killer swellings, scalds, inflammations, skin rashes, and hemorrhoids. The objective is to synthesize silver nanoparticles (AgNPs) conjugated Leaf methanol extract of B. suaveolens analyzed and characterized based on multiple (X-ray diffraction (XRD); Scanning electron microscopy (SEM); Fourier transform infrared (FTIR) spectroscopy and ultraviolet–visible (UV–Vis) spectroscopy) analytical methods. After characterization, the analgesic activity of extract bio-synthesized with silver nanoparticles was evaluated and compared with different concentrations of leaf methanol extract alone. Analgesic activity was examined by writhing and tail-flick testing. Reduction in the writhing and tail withdrawal time after administration of 250 mg/kg b.w./d of leaf methanol extract bio-synthesized with silver nanoparticle is more significant than 250, 500, and 750 mg/kg b.w./d extracts alone and is slightly less significant when compared to the standard drug. This has proved that the bio-synthesized silver nanoparticles may have played a fundamental role as drug delivery vehicles to target tissues more conveniently and efficiently compared to nascent extract.
