Summary

Chemical Constituents of the Rhizomes of Drynaria bonii Collected in Lang Son Province

Seven compounds, including daucosterol (1), arisantetralone A (2), arisantetralone B (3), p-hydroxybenzoic acid (4), protocatechuic acid (5), caffeic acid (6), and ferulic acid (7) were isolated from the 70% ethanol extract of Drynaria bonii. The structures of these compounds were identified using extensive nuclear magnetic resonance spectroscopy (NMR) data, mass spectrometry (MS), and comparison with published literatures. Compounds 2-4, 6, and 7 were reported for the first time from this species.

Keywords: Drynaria bonii, Rhizome, Sterol, Lignans, Phenolic acids.
