Abstract

Four new compounds (1-4) together with six known compounds (5-10) were isolated from the leaf extract of Garcinia nigrolineata. Compound 4 is a rare tocotrienol quinone dimer. The structures were elucidated based on NMR and MS data. All isolated compounds were evaluated for their antibacterial activities.

Keywords: Antibacterial activities; Garcinia nigrolineata; Tocotrienol; Xanthone.
