title: Geranylated flavonols from Macaranga rhizinoides.
abstract: Two geranylated and methylated flavonol derivatives, macarhizinoidins A (1) and B (2), along with a known phenolic compound methyl 4-isoprenyloxycinnamate (3), have been isolated from the methanol extract of the leaves M. rhizinoides. The structures of these compounds were identified based on their spectroscopic data. On cytotoxic evaluation against murine leukemia P-388 cells, compounds 1-2 showed IC50 values of 11.4 and 13.9 microM, respectively, while compound 3 was inactive.
