OBJECTIVE: To study the chemical constituents of Buddleja albiflora. METHOD: The constituents were isolated by column chromatography and their structures were elucidated by spectroscopic methods. RESULT: Eleven compounds were isolated and identified as luteolin (1), quercetin (2), quercetin-3-O-beta-D-glucopyranoside (3), apigenin (4), apigenin-7-O-beta-D-glucopyranoside (5), apigenin-7-O-neohesperidoside (6), acacetin-7-O-beta-L-rhamnopyranosyl-(1-6)-beta-D-glucopyranoside (7), cranioside A (8), acetylmartynoside B (9), 4"-O-acetylmartynoside (10), isomartynoside (11). CONCLUSION: All these compounds were obtained from B. albiflora for the first time and compound 8 was obtained from the genus Buddleja for the first time.
