Phenylpropanoids from Daphne aurantiaca / 中草药

ABSTRACT

Objective: To study the phenylpropanoids from Daphne aurantiaca. Methods: The constituents were separated by column chromatography, their structures were elucidated by spectral data analyses. Results: Thirteen phenylpropanoids were isolated from the EtOAc extract and were identified as caffeic acid tricosyl ester (1), caffeic acid eicosanyl ester (2), caffeic acid nonadecyl ester (3), caffeic acid octadecyl ester (4), caffeic acid heptadecyl ester (5), caffeic acid hexadecyl ester (6), caffeic acid tetradecyl ester (7), caffeic acid dodecyl ester (8), caffeic acid undecyl ester (9), caffeic acid isopentyl ester (10), ferulic acid (11), 3, 4-dimethoxy-cinnamaldehyde (12), and caffeic alcohol (13). Conclusion: The compounds are obtained from this plant for the first time.
