Aktivitas Penangkapan Radikal Bebas dari Infus Kelopak Bunga Rosella yang Difermentasi dengan Lactobacillus
Abstract: The research aimed
to investigate the free radical scavenging activity of ethyl acetate fraction
of roselle calyces infusion fermented by Lactobacillus casei strain Shirota
against free radical agent, DPPH (2,2-di-phenyl-2-picrylhydrazyl). In sequence,
the roselle calyces were extracted by infusion method with concentration at 5%
w/v. The infusion was fermented using Lactobacillus casei strain Shirota during
3x24 hours at 37⁰C. As regard the fermentation process, the result of that was
extracted using ethyl acetate. Free radical scavenging activity was measured
using DPPH method with unfermented-ethyl acetate fraction as control negative.
As the result, both fermented and unfermented-ethyl acetate fraction exhibited
free radical scavenging activity at 370.68 ppm and 685.49 ppm, respectively.
These results suggest that antioxidant activity of fermented-ethyl acetate
fraction could be 1.85 greater than unfermented-ethyl acetate fraction of
roselle calyces infusion
