Eugejambones A-D from leaves of Eugenia jambos

摘要

A new octenone, eugejambone A, a new propenone, eugejambone B and two new heptadienone derivatives, eugejambones C and D, along with 17 known compounds were isolated from leaves of Eugenia jambos . Their structures were determined by 1D and 2D NMR spectroscopic data. The cytotoxic and antibacterial activities of the isolated compounds were evaluated.
