Chemical Constituents from the Stem Bark of Styrax Perkinsiae Rhed (Ⅱ)
[Objective] The research aimed to study the chemical constituents from the stem bark of Styrax perkinsiae Rhed.[Method] The chemical constituents were separated and purified by chromatographic methods after solvent extraction and were identified by spectroscopic analyses.[Result] Seven compounds were isolated from CHC13 fraction of the stem bark of Styrax Perkinsiae Rhed and identified as following: Oleanolic aldehyde acetate (1), 3β-Acetoxyolean-12-en-28-acid (2), (7R, 8R, 8R')-3, 3'-Dimethoxy-7, 9'-epoxylignane-4, 4', 9-triol (3), 9-Hydroxyl piperonol (4), 7 'R-Hydroxylariciresinol (5), 7 '-methoxy-laricireslnol (6), Uridine (7).[Conclusion] Five compounds (3-7) were isolated from the plants of Styrax for the first time.
