title: Cytotoxic flavonoids from Vitex agnus-castus.
abstract: Four new flavonoids, luteolin 6-C-(4"-methyl-6"-O-trans-caffeoylglucoside), luteolin 6-C-(6"-O-trans-caffeoylglucoside), luteolin 6-C-(2"-O-trans-caffeoylglucoside), and luteolin 7-O-(6"-p-benzoylglucoside), together with four known ones 5, 4'-dihydroxy-3,6,7,3'-tetramethoxyflavone, luteolin, artemetin and isorhamnetin, were isolated from the root bark of Vitex agnus-castus. The structures were elucidated by spectroscopic means.
