Phytochemical investigation of the branches of Viburnum awabuki K. Koch and its chemotaxonomic significance

Abstract

Phytochemical investigation of the branches of Viburnum awabuki K. Koch led to the isolation of thirteen known compounds, including five lignans (1-5), one phytosterol (6), two phenylpropanoids (7-8), one chromone derivative (9), three pentacyclic triterpenoids (10-12), and one glyceride (13). The structures of these compounds were elucidated through extensive spectroscopic analyses and comparison of experimental data with literature data. Additionally, the chemotaxonomic significance of the isolated secondary metabolites was also discussed.
