Abstract

It has been done screening fitokimia and the determination of free antiradical activity extract methanol of
gaharu leaf. The screening fitokimia determined by the colour test and free antiradical activity determined by
diphenyl pykril hydrazil (DPPH) method according to sphectrophotometry UV-Vis, before that the honey was diluted
with methanol and then the absorbance was measured on 497nm, 517 nm, and 537 nm. The result showed that
methanol extract of gaharu leaf contain phenol, flavonoid and terpenoid compound and the free antiradical activity
showed inhibitor percent is 106,32 % (5”) and 111,31 % (60’).
