Abstract:
Objective To study the chemical constituents from the leaves of Magnolia delavayi. Methods The chemical constituents were isolated and purified by column chromatography on silica gel, Sephadex LH-20, MCI, and HPLC. Their structures were identified based on spectroscopic data. Results Fourteen compounds were isolated from 95% ethanol aqueous extract of M. delavayi and the structures were identified as (2E)-3,7,11-trimethyl-2,10-dodecadien-l,6,7-triol (1), (2E,6E)-3,7,11-trimethyl-2,6-dodecadien-l,10,11- triol (2), loliolide (3), pinoresinol (4), syringaresinol (5), medioresinol (6), eudesmin (7), phillygenin (8), coniferaldehyde (9), 3,4,5-trimethoxycinnamyl alcohol (10), indole-3-carboxaldehyde (11), indole-3-ethanol (12), 3,4-dimethoxy-benzoic acid (13), and 3,4-dimethoxyphenol (14). Conclusion All compounds are isolated from this plant for the first time. In addition, the 1H- and 13C-NMR spectroscopic data are reported for the first time in the current study.
