Abstract: Two new norbisabolane sesquiterpenoid glycosides, glochicoccinosides A (1) and B (2), together with two known compounds, have been isolated from the rhizomes of Glochidion coccineum. Their structures were elucidated by the combination of 1D NMR, 2D NMR, and MS spectral analysis, as well as chemical evidence. Cytotoxic activities and the antioxidant effect of these compounds were evaluated, but none of them showed activity.
