dc.description.abstract | Background. Jackfruit (Artocarpus heterophyllus) is one of the tropical plants in
the Asian region, known to have various potential health benefits. Parts of this
plant, such as leaves, stems, and roots, are rich in bioactive compounds that have
the potential to serve as natural antioxidants. Antioxidant activity is crucial in
combating free radicals that can damage body cells and contribute to various
degenerative diseases. Phytochemical screening of jackfruit leaf, stem, and root
extracts is necessary to identify secondary metabolites or active compounds with
antioxidant activity. Objective. To determine the secondary metabolites and
antioxidant activity of ethanol extracts of leaves, stems and roots of jackfruit
(Artocarpus heterophyllus). Method. Ethanol extracts of leaves (EEDN), roots
(EEAN) and stems (EEBN) of jackfruit were obtained by maceration using a 96%
ethanol solvent. Qualitative phytochemical screening is carried out to identify
secondary metabolites in the form of alkaloids, flavonoids, saponins, glycosides,
steroids and tannins. The antioxidant activity test was carried out by the 2,2-
diphenyl-1-picrylhydrazyl (DPPH) method. Results. The three extracts (EEDN,
EEAN and EEBN) showed the presence of secondary metabolites of alkaloids,
flavonoids, saponins, glycosides and tannins. Only EEBN does not contain steroid
compounds. Furthermore, the antioxidant activity of EEAN was stronger than that
of EEBN and EEDN (IC50: 47.18 < 112.68 < 157.08 ppm). Conclusion. Jackfruit
root, stem and leaf extracts contain secondary metabolites of alkaloids, flavonoids,
saponins, glycosides and tannins. The root extract shows the most potent
antioxidant activity. | en_US |
