Antioxidant activities of medang lendir (Litsea glutinosa) stem bark

Background: Medang lendir (Litsea glutinosa), a member of the Lauraceae family, is typically found in Kampar Regency area Riau Province, Indonesia. This plant frequently used traditional medicine to treat rheumatism, diarrhea, and dysentery. Objective: To evaluate antioxidant activities L. glutinosa stem bark extracts. Method: was macerated methanol obtain extract, followed by partitioning with ethyl acetate extract. The these extracts were determined using NO radical scavenging DPPH methods. Folin-Ciocalteu method also this study determine total phenolic content (TPC). Result: against radicals resulted small percentage inhibition (%I < 0). Meanwhile, for scavenging, activity extract (IC50 = 222.03 ug/mL) greater than 232.81 ug/mL), TPC value (23.88 mgGAE/g) (23.16 mgGAE/g). Conclusion: These results show that based on both active; however, it inactive radicals. possessed higher compared
