概要
Bioassay-directed fractionation of an ethanolic extract of Selaginella moellendorffii has led to the isolation of a known biflavone, ginkgetin (1). A dose-dependent inhibition was observed with 1 on the growth of OVCAR-3 (human ovarian adenocarcinoma) cells with 50% inhibition occurring at 1.8 micrograms/mL. Nonbioactive fractions yielded four additional known biflavones, amentoflavone 7,4',7",4"'-tetramethyl ether, kayaflavone, podocarpusflavone A, and amentoflavone.
