Protocatechuic acid

Phytochemical study of Knema saxatilis stems led to the isolation of six known compounds. Their chemical structures were determined as 8-hydroxy eriodictyol (1), (2S)-7-hydroxy-3′,4′-methylenedioxideflavan (2), sitostenone (3), protocatechuic acid (4), 4-hydroxybenzoic acid (5) and vanillin (6) using NMR and MS spectral data.
