Abstract:
Objective To study the chemical constituents from the wing twigs of Euonymus alatus. Methods Compounds were isolated and purified repeatedly on silica gel, Sephadex LH-20, open RP-C18 column chromatographies and PTLC, and their chemical structures were elucidated by their physicochemical properties and spectral data, such as 1H-NMR, 13C-NMR, and EI-MS. Results Nine compounds were obtained and identified as: epifriedelinol (Ⅰ), stigmast-4-en-3-one (Ⅱ), 6?-hydroxy-stigmast-4-en-3-one (Ⅲ), ?-sitosterol (Ⅳ), methyl 2, 4-dihydroxy-3, 6-dimethyl benzoate (Ⅴ), methyl 2, 4-dihydroxy-6-methyl benzoate (Ⅵ), 7-methoxy-4-methylphthalide (Ⅶ), vanillin (Ⅷ), n-octacosanol (Ⅸ). Conclusion Compound Ⅶ is first reported as a natural product. Compounds Ⅴ-Ⅷ are reported from plants of Euonymus L. for the first time.
