Abstract

Objective: This study aimed to investigate the chemical components present in the ethyl acetate extract of Styrax dasyanthus leaves.

Methods: Chemical components were isolated and purified using organic solvent decolorization, extraction, preparation of the liquid phase, silica gel column chromatography, and semi-preparative high-performance liquid chromatography. The structure identification of the isolated compounds was based on nuclear magnetic resonance (NMR) data and carbon spectrum matching analysis.

Results: A total of six compounds were isolated from Styrax dasyanthus, which were identified as (-)-secoisolarciresinol (1), dibutylphthalate (2), dihydromyricetin (3), kaempferol-3-O-\(\beta\)-D-glucopyranoside (4), kaempferol-3-rutinoside (3,4',5,7-tetrahydroxyflavone-3-rutinoside) (5), and (-)-secoisolariciresinol-4-O-\(\beta\)-D-glucopyranoside (6).

Conclusion: This study represents the first isolation of these six compounds from Styrax dasyanthus.

Keywords: Styrax dasyanthus, (-)-secoisolarciresinol, dihydromyricetin, kaeMpferol-3-O-\(\beta\)-D-glucopyranoside
