Antioxidant activity test and phytochemical screening of ciplukan extract (physalis angulata) as an alternative feed additive in poultry

Abstract This study aimed to test antioxidant activity and perform phytochemical screening of ecstak ciplukan (Physalis angulata) as an alternative feed additive in poultry. Methods used include extraction and identification of phytogenic content from ciplukan extract. Variables observed include antioxidant activity, phytochemical components, as well as Total Flavonoid Content (TFC), Total Phenolic Content (TPC), and Total Tannin Content (TTC). Data analysis is carried out descriptively and tabulated according to the study variables. The results of the study showed that ciplukan extract contains bioactive compounds such as alkaloids, steroids, saponins, flavonoids, and phenolics. TFC, TPC, and TTC assays showed consecutive values of 517,895 mgQe/g, 681,818 mgGae/g, and 114,286 mgTae/g. In addition, ciplukan extract has a strong classified antioxidant activity with an IC50 value of 88.67 ppm. The study concluded that ciplukan extract has potential as an alternative feed additive for poultry because it contains bioactive compounds and has strong antioxidant activity.
