Abstract
Four hydrolyzable tannins named balanophotannins D-G (1-4) were isolated from the aerial parts of the parasitic plant Balanophora japonica. Their structures were characterized on the basis of spectroscopic and chemical evidence. Balanophotannins D-G contain an oxidized hexahydroxydiphenoyl (HHDP) group. The absolute configurations of balanophotannins D (1) and F (3) were determined via the PGME method. Balanophotannin E (2) showed cytotoxicity to Hep G2 cancer cells with an IC50 value of 4.22 μM.
