Objective To investigate the chemical constituents in the flower buds of Lonicera confusa. Methods The chemical constituents were isolated by repeated silica gel chromatography, Sephadex LH-20, medium pressure column chromatography, and semi-preparative HPLC, and their structures were elucidated by spectroscopic analyses and comparison of NMR data with those reported in literature. Results Ten compounds were isolated and identified to be chlorogenic acid (1), quercetin (2), luteolin (3), luteolin-3'-O-α-L-rhamnopyranoside (4), apigenin-7-O-α-L-rhamnopyranoside (5), trans-cinnamic acid (6), p-hydroxy benzaldehyde (7), gentisic acid-5-O-β-D-glucopyranoside (8), benzyl-β-D-glucoside (9), and abscisic acid (10). Conclusion Compounds 4—10 are obtained from this plant for the first time.
