| Abstract: | Six new pentacyclic triterpenoids were isolated from the fruit of Camptotheca acuminata. The chemical structures of the new compounds were elucidated by extensive spectroscopic analysis including HR‐ESI‐MS, IR, UV, 1D‐ and 2D‐NMR. Moreover, the antibacterial activities of compounds 1 , 2 , 4 , 5 , and 6 were evaluated against Staphylococcus aureus, Escherichia coli, Bacillus subtilis and Dickeya zeae. All these tested compounds showed moderate antibacterial activity against Bacillus subtilis and Dickeya zeae. |
