Antioxidant Activity of Leave’s Extract and Isolate Ketepeng Kebo Cassia alata Linn (Leguminoceae)
Abstract: Phytochemistry and
biological activity investigation
of medical plants was an important step in exploring of
their potency. The objectives of this research were to
determine the antioxidant
activity of the
extract and purified
isolate of C.alata
leave and also,
to elucidate of
the molecular structure
of the responsible molecule. The methods used were
extraction, isolation and purification by means of chromatography, DPPH radical
scavenging and spectroscopy. Result of the research provided antioxidant
activity was (ED50)
28.50±1.86 µg/mL for
the extract and 9.99±0.28
µM for the
purified isolate. Elucidation
toward the purified
isolate indicated kaemferol structure
as the most
active antioxidant compound.
