A new natural C-benzylated chalcone, $2',4'-dihydroxy-3'-(2-hydroxybenzyl)-6{\c}-methoxychalcone$ (2), along with two other flavonoids, tiliroside and kaempferol 3-O-rutinoside, and an oxoaporphine alkaloid, lanuginosine were isolated from the aerial parts of Ellipeiopsis cherrevensis (Annonaceae). Two known polyoxygenated cyclohexene derivatives, ferrudiol and zeylenol, and a new analog, ellipeiopsol D, were also isolated. The chalcone 2 exhibited cytotoxic activity against human small-cell lung-cancer (NCl-H187), epidermoid carcinoma (KB) and breast cancer (BC) cell lines with $IC_{50}$ values of 1.40, 5.31 and $13.92\;{\mu}g/mL$, respectively. This compound also showed antimalarial activity against Plasmodium falciparum with an $IC_{50}$ value of $7.1\;{\mu}g/mL$ as well as antimicrobacterial activity against Mycobacterium tuberculosis with a MIC of 25 mg/mL.
