Background: From time immemorial herbal preparations are been employed for the treatment of several ailments. In recent years due to poor bioavailability the conventional herbal preparations are replaced by phytoniosomes, an advanced novel drug delivery system in which the herbal extracts are incorporated into a non-ionic surfactant to yield higher absorption and remarkable desired pharmacological activity. The present study is aimed to prepare and characterize the ethanolic leaf extract of (nELETC) loaded phytoniosome and to compare its antioxidant properties with ethanolic leaf extract of (ELETC).
Methods: The ethanolic leaf extract and ethanolic leaf extract of loaded phytoniosome (ELETC and nELETC) were prepared. The characterization of the prepared phytoniosomes were performed by UV-Visible spectroscopy, FTIR, XRD, SEM, TEM, DLS and zeta potential. The nontoxic nature of the prepared phytoniosomes was analyzed using MTT assay in vero cell line. The antioxidant potential of ELETC and nELETC were compared by the scavenging activity of DPPH, Hydrogen peroxide and Superoxide radicals.
Results: The formation of ethanolic leaf extract of loaded phytoniosome (nELETC) was confirmed with UV-Vis spectroscopy. The SEM and TEM images confirmed the spherical shape of the nELETC with average size ranging from 600 to 1800 . The zeta potential showed magnitude of -65.55 to -77.83 and its crystalline structure was confirmed by XRD analysis. Through the FTIR spectrum presence of alcohols, alkanes, phenols, esters, aliphatic and aromatic compounds as well as alkenes and carbolic acids were identified. MTT assay establishes the non-toxic nature of the synthesized nELETC and excellent antioxidant potential was observed for nELETC than ELETC.
Conclusion: In conclusion, the ethanolic leaf extract of loaded phytoniosome (nELETC) will serve as a promising drug carrier in scavenging the free radicals and can be used in various biological applications.

This study aims to assess the impact of extract on periodontitis in rats, using the Papillary Bleeding Index (PBI), gingival index (GI), and histological evaluation of key inflammatory cells such as osteoclasts, osteoblasts, polymorphonuclear neutrophils (PMNs), macrophages, and fibroblasts to explore its potential in reducing inflammation and preserving periodontal tissue.The extract was prepared using the reflux method with 96% ethanol as a solvent, followed by phytochemical screening and antibacterial testing via the disk diffusion method. This study utilized a posttest control group experiment with 24 Wistar rats, divided into four groups: nonperiodontitis, no-treatment, chlorhexidine-treated (CHX), and extract-treated groups, with the latter three groups induced with periodontitis.

Background: The development of new drugs that act against multidrug-resistant microorganisms and malignant tumors is necessary owing to the limited therapeutic options and high mortality rates associated with these pathologies. In this study, we evaluated the phytochemical groups present in seven plants from the Brazilian Cerrado even as their antioxidant, antiproliferative and antimicrobial activities.
Methods: The extracts were obtained by the maceration technique and secondary metabolites were determined by phytochemical analysis.
