N1  - ABSTRACT     EVALUATION OF THE ANTIOXIDANT     Title : LEVELS OF THE PARTIAL FRACTIONS OF BALAKAT (Ziziphus talanai (Blanco) Merr.)     Researcher : JAMAICA A. MACAPAGAL     School : Pampanga State Agricultural University, PAC, Magalang, Pampanga     Degree : Bachelor of Science in Biology     Date Completed March 2018     Adviser Ruth T. Libag, MAEChem     ee     The Balakat (Ziziphus talanai) leaves were extracted with ethanol. The ethanol extract was fractioned with DCM, methanol and hexane using modified Kupchan partitioning method. The solvent fractioned were subjected to test the DPPH free radical scavenging activities. It was then read through spectrophotometer and was computed using the ascorbic acid equivalent antioxidant capacity (AEAC) using the formula y=mx+b. The DCM fraction has the highest AEAC with an amount of 11.188yg/ml, followed by methanol fraction with an amount of 6.97lpg/ml and hexane fraction with an amount of 6.143pg/ml. All of the partial isolates of Balakat (Ziziphus talanai) possess antioxidant potential against the stable radical DPPH. The hexane and methanol fractions have almost similar antioxidant capacity and OCM fraction has the highest antioxidant capacity
