Comprehensive Summary: 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. [ABSTRACT FROM AUTHOR]
