Identifikasi struktur isolat aktif antioksidan dilakukan dengan spektrofotometer UV-Vis , serta aktivitas antioksidan ditentukan dengan dengan metode DPPH (1,1-difenil-2-pikril-hidrazil). Hasil isolasi senyawa aktif antioksidan diperoleh isolat A1 dan A2 yang diduga merupakan senyawa flavonoid golongan khalkon. Uji aktivitas antioksidan diketahui bahwa fraksi etil asetat memiliki potensi yang kurang bagus sebagai antioksidan dengan harga IC 50 353,41 ppm.}, issn = {2597-9914}, pages = {69--72} doi = {10.14710/jksa.16.3.69-72}, url = {https://ejournal.undip.ac.id/index.php/ksa/article/view/18113} }
