A new compound, schistochilic acid D (1) and two known compounds (2 and 3) were isolated from MeOH extract of Bornean liverwort. Schistochila acuininata collected from Mount Trus Madi, Sabah. The structure of the new metabolite was established based on spectroscopic (ID NMR, 2D NMR, and IR). and HRESIMS data. In addition, another population of S. acuminata collected from Mount Alab (Sabah) yielded four known compounds, 2, 3, 4 and 5. These compounds were tested for their biological potential against the B 16-Fl0 cell line. Compounds 4 and 5 exhibited weak cytotoxic activity.
