Two New Phloroglucinol Derivatives with Phosphodiesterase Inhibitory Activity from the Leaves of Eucalyptus robusta

Abstract

Two simple, new phloroglucinol derivatives have been isolated from the leaves of Eucalyptus robusta Smith, used in the Chinese traditional medicine Da Ye An. These phenolic compounds were purified using a phosphodiesterase inhibition bioassay to guide the isolation. Both compounds had moderate activity in this bioassay. © 1991, Verlag der Zeitschrift.
