A novel pharmacological approach of herbal mediated cerium oxide and silver nanoparticles with improved biomedical activity in comparison with Lawsonia inermis

摘要

Diabetes mellitus is one of the threatening, non-communicable and chronic ailments worldwide since ancient times to the current stage of human existence. The utilization of nanoparticles as a medicine in the treatment of diabetes is an attractive proposition. In the present study, herbal mediated cerium oxide nanoparticles (HMCeO2 NPs), herbal mediated silver nanoparticles (HMAg NPs) and Lawsonia intermix extract (LIE) was evaluated for them for in-vivo hypoglycemic effect and compared the potency. The resulting HMCeO2 NPs, HMAg NPs and Lawsonia inermis have been characterized by different analytical equipments such as X-ray Diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), Particle size analyzer (PSA), Field emission scanning electron microscope (FESEM) and High resolution transmission electron microscope (HRTEM). The synthesized NPs and Lawsonia inermis extract were assessed for toxicity by using acute oral toxicity using female albino mice (s) model by following OECD-425 guidelines. In in-vivo hypoglycemic animal model, the male wistar rats with weight varying between 180-200 gins were grouped as: normal control: did not receive any treatment, diabetic control (saline): received a single intraperitoneal dose of Streptozotocin (40 mg/kg), standard: received a single daily oral dose of 50 mg/kg body weight, HMCeO2 NPs: received single daily oral dose of 100 mg/kg, 200 mg/kg, HMAg NPs: received a single daily oral dose of 100 mg/kg, 200 mg/kg, and Lawsonia inennis: received a single daily oral dose of 100 mg/kg, 200 mg/kg. The herbal mediated NPs were considered safe as they have not shown toxic effects. From the current study results, it may conclude that, due to the advanced biological and pharmacological characters, the HMAg NPs depicted more potent hypoglycemic activity than that of LIE and CeO2 NPs.
