Isolation of a nitrobenzoate from the leaves of Cinnamomum tenuifolium

Investigation of leaf extract of Cinnamomum tenuifolium (Lauraceae) led to the isolation of one new nitrobenzoate, ethyl 3,5-dihydroxy-4-nitrobenzoate (1), along with four known compounds. This is the first report of Cinnamomum metabolites with a nitro benzenoid derivative. Their structures were determined through in-depth spectroscopic and mass spectrometric analyses.
