Abstract:

Background: Antioxidant plays a vital role in scavenging of free radicals, thus, providing protection against oxidative stress. Now the modern research is directed towards the discovery of herbal antioxidants and immnomodulators due to their lesser side effects. Objective: The aim of the present study is to evaluate the antioxidant and immunomodulatory potential of methanolic extract of Juniperus squamata from the Apharwat region of Gulmarg. Materials and method: The antioxidant activity of methanol extract of Juniperus squamata was evaluated by using 1, 1-diphenyl, 2-picrylhydrazyl (DPPH) scavenging, reducing power, hydroxyl radical scavenging, hydrogen peroxide scavenging activity and lipid peroxidation. Furthermore, the immunomodulatory potential of the extracts was investigated through the Delayed type hypersensitivity and phagocytic carbon clearance assay. Results: The highest phenolic content of 780 GAE/g (Total phenolic content) was observed in the methanolic extract, while the lowest Total phenolic content of 459 mg GAE/g was achieved in the petroleum ether extract. At a concentration of 700 g/mL, DPPH radical scavenging activity was found to be highest in methanolic extract (82.12%). Methanol extract was found to be an efficient scavenger of hydrogen peroxide radical and lipid peroxidation with IC50 values of 161.44 ± 0.08 μg/mL and 78.65 μg/mL respectively. Administration of plant extract (100 and 200 mg/kg body weight) increased the DTH response and phagocytic carbon clearance significantly. Conclusion: The results indicate that the methanolic leaf extract of Juniperus squamata has good antioxidant and immunomodulatory potential.

About Journal

Founded:  In 2004, as the PHCOG.NET – a non-profit private organization dedicated to Natural Products Research leading to develop promising drugs. Our main mission is to make information on herbal drug research readily available in different formats to suit the individual needs. About Journal : Free Radicals and Antioxidants [ISSN: 2231-2536] is an online peer reviewed publication dedicated to publishing novel, original findings in the field of free radical biology and both natural and synthetic antioxidants. Free radicals, which are defined as molecules containing one or more unpaired electrons in their outmost atomic or molecular orbital have emerged as double edged swords.The Free Radicals and Antioxidants Journal aims to foster the dissemination of scientific information by publishing manuscripts that provide new insights into the biology of free radicals, including their generation, degradation, modulation, role in cellular function and cell signaling. The submission of uninvited expert reviews and research articles in all areas of Free Radical Biology and Antioxidants are also welcomed. Free Radicals and Antioxidants publishes full research papers presenting original, high quality research, critical review articles providing comprehensive analysis of research development within a defined area and editorial commentaries on key topical issues in Free Radical and Antioxidant Biology.
