Abstract
Stachytarpheta jamaicensis (L.) Vahl leaves contains
secondary metabolites in the form of flavonoids, which can be used as a source
of antioxidants. All flavonoids have been reported to undergo some form of
degradation with exposure to physico-chemical environmental factors. This study
aims to identify the compound content and determine the antioxidant activity of
horse whip leaf extract. Identification of compound content by TLC method and
antioxidant activity in reducing ABTS radicals using a UV-VIS spectrophotometer
which is then expressed in IC50 value. Extraction by maceration method placed
at room temperature, namely 30oC. The results of the identification
of the compounds contained in the horse whip leaf extract were positive for
flavonoids, saponins, tannins and terpenoids. ABTS method antioxidant activity
with IC50 value 39.41 ppm is included in the very strong antioxidant category
because it is < 50 ppm compared to Vitamin C which IC50 value is 4.07 ppm.
It can be concluded that the very strong activity of the ethanol extract of
horse whip leaves is thought to be due to its compound content, one of which is
the antioxidant compound content, namely flavonoids.
