INVITRO ANTIOXIDANT ACTIVITIES OF VARIOUS LEAVES EXTRACTS FROM FIVE VARIETIES OF RAMBUTAN (Nephelium lappaceum) AND ITS CORRELATION WITH TOTAL FLAVONOID, PHENOLIC, CAROTENOID CONTENT

Objectives: The objectives of this research were to study antioxidant activity from different polarities extracts of rambutan (Nephelium lappaceum) leaves using two methods of antioxidant testing which were 2-2-diphenyl-1-picrylhydrazyl (DPPH) and 2-2’-azinobis (3-ethyl-benzothiazoline-6-sulfonic acid) (ABTS) and correlation of total flavonoid, phenolic and carotenoid content in various extracts of rambutan leaves with DPPH and ABTS antioxidant...
