Objective: To study the constituents from Sophora flavescens.
Methods: Separating the constituents by means of chromatography and identifying their structures on the basis of spectral analysis.
Results: The five compounds obtained were identified as sucrose, lignoceric acid, beta-sitosterol, sinapic acid hexadecyl ester and umbelliferon.
Conclusion: Sinapic acid hexadecyl ester is a new compound. These compounds were obtained from the plant for the first time.
