Antiallergic dimeric prenylbenzoquinones from Ehretia microphylla
Abstract
The ethyl acetate-soluble portion of the MeOH extract of Ehretia microphylla showed inhibitory activity on exocytosis in antigen-stimulated rat basophils. The bioassay-guided separation of this fraction afforded five biologically active compounds. By means of chemical and spectroscopic methods, the structures of these compounds, which include microphyllone, a unique dimeric prenylbenzoquinone, and its congeners, were elucidated. © 1995 Elsevier Science Ltd.
