Abstract
The research of volatile compound of Piper crocatum leaf extract has been done. The aim of research is to know the volatile compound of Piper crocatum leaf extract. The research was started by extraction of Piper crocatum leaf. This extraction method used maceration and reflux with etanol 96%. Component in the extract were identified using of GC-MS method. DPPH (2,2-diphenyl-1picrylhydrazyl) method was used on activity test of antioxidant. The result showed that volatile compound of Piper crocatum leaf extract were dominated by the monoterpenes, which were sabinene and myrcene. Antioxidant activity test with DPPH method to leaf extract faction of Piper crocatum, known that extract by maceration and reflux have potency as antioxidant with value of IC50 of 46,51 ± 0.05 (AAEµg/ml) and 49,57 ± 0.27 (AAEµg/ml) respectively. Antioxidant capacity of Piper crocatum leaf extract by maceration and reflux were 10892,86 ± 6,06 (AAEµg/ml) and 9971,43 ± 6,06 (AAEµg/ml).
