Gerunggang (Cratoxylum arborescens (Vahl.) Blume) is one of the plants from Hypericaceae that has benefits. From several studies that showed Hypericaceae has antioxidant activity and potential as a source of natural antioxidants. An investigation on the antioxidant activity of gerunggang extract has been done using 1-1-diphenyl-2-picrylhydrazyl (DPPH) method. The extract was obtained by macerating the stem barks of cratoxylum arborescens using n-hexane, ethyl acetate and methanol respectively. The antioxidant activity test was performed quantitative using microplate reader with ascorbic acid as a standard. The result showed that IC50 value of n-hexane extract, ethyl acetate extract and methanol extract of gerunggang sequentially 82.058 μg/mL ; 12 µg/mL and 8.335 µg/mL. methanol extract has the highest antioxidant activity that is 8.335 µg/mL.
