OBJECTIVE
To study the chemical constituents of Buddleja albiflora.
METHODS
The constituents were isolated by column chromatography and their structures were elucidated by spectroscopic methods.
RESULTS
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).
CONCLUSIONS
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.
