Abstract:
Two new methoxyflavone glycosides: chrysoeriol-7-O-(2,6-dirhamnosyl)-glucoside and chrysoeriol-7-O-neohesperidoside and seven other known flavonoids, were isolated and characterised from the aerial parts of Verbena bipinnatifida Nutt. (Verbenaceae). Their structures were elucidated by spectral and chemical methods of analysis.
