RESUMEN
Objective To investigate the anti-H5N1 activities and chemical constituents from stems and leaves of Buddleja lindleyana Fort. Methods Constituents were separated through AB-8 macroporous resin, chromatography of silica gel, Sephadex LH-20 and recrystallization. Structures of the compounds were identified by analysis of physicochemical properties and spectral data. Results Ten compounds were isolated and identified as linarin(l), rutin(2), luteolin(3), quercetin(4), apigenin(5), hesperetin (6), salidroside (7), oleanolic acid (8), ß-sitosterol (9), and daucosterol (l0), respectively. Conclusion Compounds 2-7 were obtained from this plant for the first time.
