Phenolic Compounds Isolated from Fruits of Cornus officinalis Sieb. et Zucc.

Abstract

 In this study, six phenolic compounds were isolated from the ethyl acetate of Cornus officinalis, including: Gallic acid (1), dimethyl malate (2), 1,4-dimethyl ester 2-(2-formyl-1H-pyrrol-1-yl)butanedioic acid (3), stageobester A (4), coroffester (5), and methyl caffeate (6). The structure of the compounds was determined by such spectroscopic methods as MS, NMR and by comparison with the published NMR data. This is the first time compounds 3-5 have been isolated from this species.
