ISOLASI DAN IDENTIFIKASI SENYAWA METABOLIT SEKUNDER DARI EKSTRAK ETIL ASETAT PADA KULIT BATANG MEDANG LENDIR (Litsea glutinosa)

Abstract

The stem bark of Litsea glutinosa (Medang lendir) from the Lauraceae family has been used as mosquito repellent by indigeneous community in Kampar Kiri Hulu sub-district, Riau Province. In this study, a secondary metabolite was isolated from ethyl acetate extract of Litsea glutinosa stem bark. The pure compound from vial of 6th was separated by flash chromatography method. The UV/VIS spectrum showed maximum absorption at 265 nm. The characterization of the compound was determined by FT-IR spectroscopy which showed the presence of the OH group, cyclic alkene C=C, aromatic carbonyl ester C=O, aliphatic C-H, and ester C-O.
