Abstract

Scopoletin has been isolated from chloroform fraction of methanolic extract of Mengkudu fruit (Morinda citrifolia L). Its structure was confirmed using infra red spectroscopy and mass spectroscopy. Scopoletin revealed a scavenging activity of 2,2’-diphenil-1-picrylhydrazil (DPPH) radical by IC 50 348.79 μg/mL, 35 times lower than that of vitamin E (IC 50 9.77 μg/mL). Furthermore, scopoletin also showed an antioxidant activity which was lower than that of vitamin E by using linoleic-thiocyanate method.ABSTRAKSkopoletin telah diisolasi dari fraksi kloroform ekstrak metanol buah mengkudu (Morinda citrifolia L) yang strukturnya dikonfirmasikan dengan spektroskopi inframerah dan spektrometri massa. Skopoletin menunjukkan aktivitas penangkapan radikal 2,2’-difenil-1-pikrilhidrazil (DPPH) dengan nilai IC50 348,79 μg/mL, 35 kali lebih lemah dibandingkan dengan vitaminE (IC50 9,77 μg/mL). Skopoletin juga mempunyai aktivitas antioksidan yang lebih lemah dibandingkan dengan vitamin menggunakan metode linoleat-tiosianat.
