Abstract
The crude chloroform bark extract of Syncarpia glomulifera (Myrtaceae) shows antibacterial and cytotoxic activity. Bioactivity-directed separation led to the isolation of oleanolic acid-3-acetate, ursolic acid-3-acetate and betulinic acid. The relatively large abundance (10 % of the crude extract) and high degree of activity of betulinic acid are responsible for the bioactivity of the crude bark extract.
