Antibacterial activity of lupeol from the bark of Dehaasia cuneate (Lauraceae)
Current Research on Biosciences and Biotechnology
Dehaasia is a member Lauraceae. It is locally known as 'gajus hutan' or 'pekan'. A triterpenoid, lupeol was isolated from the bark of Dehaasia cuneate. The structure of the isolated compound was determined using spectroscopic methods, such as UV–vis, FT-IR, 1D and 2D NMR, and mass spectrometer. The isolated compound was tested against Gram-negative and positive bacteria using agar disc diffusion technique. The results showed that lupeol had a moderate inhibition zone value of 10.0±0.00 mmdoi:10.5614/crbb.2021.2.2/bofy6724 fatcat:cwei7dy3tjgixn55zd7wntjepe
