dc.description.abstractA coffee tree parasite (Loranthus ferrugineus) is a type of parasitic plant that is widely used as a medicinal plant. This study aimed to isolate and characterize the pure compound obtained from the n-hexane extract of the its stem and also to perform antioxidant tests on the extract. Isolation process was carried out by the maceration method in using n-hexane as solvents, repectively. The plant extracts were dried and then separated using vacuum liquid chromatography (VLC). A solid fraction were collected and then recrystallized to give a pure compound. This compound has a melting point of 76-78oC. This compound is than coded LF-H-03. Pure compound was characterized using FTIR. The peak of FTIR spectroscopy showed absorption at aliphatic wave numbers 2954 cm-1 (C-H), 1736 cm-1 (C=O) and 1472 cm-1 (CH2). Based on the results of the antioxidant n-hexane extract from the stem of the L. ferrugineus plant were active with IC50 values of 138.93 μg/mLen_US
