Dichagelinoids A-C (1-3), three unusual dichapetalin-type triterpenoids, together with two biogenetically related derivatives dichagelinoids D and E (4 and 5) were isolated and characterized by solid data from Dichapetalum gelonioides. Compounds 1-3 possess a common rearranged C ring and different C6-C2 modified motifs at the A rings. Biological evaluation revealed that compounds 1-3 showed distinct cytotoxic activity against the tested human cancer cell lines.
