Averrhoa carambola L. leaves have long been utilized in traditional medicine. This study aimed to assess the
anti-inflammatory potential of A. carambola L. leaf extracts through a lipoxygenase inhibition assay, focusing
on the ethanol fraction derived from leaves collected in Ahomgaon, Assam. The extraction process was carried
out using the Soxhlet method, initially with petroleum ether, followed by 95% ethanol. The ethanol fraction was
then evaluated for its lipoxygenase inhibitory activity using linoleic acid as the substrate, while its total flavonoid
and total phenol contents were also quantified. The correlation between IC50 values and the total flavonoid and
total phenol contents in the ethanol fraction was analyzed. Results showed that the ethanol fraction inhibited
lipoxygenase enzyme activity, with an IC50 value of 96.86 µg/mL.
