Abstract:

Objective: The present study was conducted to investigate the antioxidant and anti-clastogenic activity of fractions extracted from Morusalba (Moraceae) leaves. Methods: The leaves of Morus alba were sequentially extracted using n-Hexane, Petroleum Ether, Ethyl Acetate, Methanol and Water, and Total phenolic content was determined using Folin-Ciocalteau (FC) reagent. The anti-oxidant property of each fraction was determined using 2-Deoxy-D-ribose, 2, 2-Diphenyl-1-picryl-hydrazyl (DPPH) and Hydroxyl radical scavenging assay. Furthermore, anti-clastogenic potential of these fractions was determined using calf-thymus DNA in the presence of Fenton’s reagent followed by analyzing the samples by agarose gel electrophoresis. Results: All fractions showed the presence of varied amounts of total phenols and exhibited anti-oxidant activity as determined by scavenging the corresponding radicals. Among these fractions the methanol fraction (MEMA) showed the maximum phenol content as well as anti-oxidant activity. In addition MEMA could inhibit the breakage of DNA strands (anti-clastogenic activity) compared to other fractions tested. Discussion: Results of this study suggests that MEMA is likely to possess better antioxidant and anti-clastogenic activity.

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.
