OBJECTIVE: To investigate the chemical constituents of the dried buds of Lonicera confusa. METHOD: Chromatography and spectral analysis were respectively used to isolate and identify the constituents. RESULT: Seven compounds were isolated from the dried buds of L. confusa, and identified as rutin, quercetin, luteilin-7-O-beta-D-galactoside, lonicerin, chlorogenic acid, beta-sitosterol and tetratriacontane. CONCLUSION: Rutin was isolated from the genus for the first time, and the others were isolated from the species for the first time.
