Chemical constituents from stem bark of Styrax perkinsiae / 中草药

ABSTRACT

Objective: To study the chemical constituents from the stem bark of S. perkinsiae. Methods: The chemical constituents were separated and purified by chromatographic methods after solvent extraction and were identified by spectroscopic analyses. Results: Ten lignans were isolated from the stem bark of S. perkinsiae and identified as following obassioside B (1), lariciresinol 4-O-β-D-glucoside (2), (-)-secoisolariciresinol 4-O-β-D-glucopyranoside (3), lariciresinol 4′-O-β-D-glucoside (4), lanicepside A (5), isolariciresinol 4-O-β-D-glucopyranoside (6), (+)-lariciresinol 9-O-β-D-glucopyranoside (7), isotachioside (8), 2R*, 3S*-dihydro-dehydrodiconiferyl alcohol 4′-O-β-D-glucopyranoside (9), and pinoresinol (10). Conclusion: Eight compounds (2-9) are isolated from the plants of Styrax Linn. for the first time.
