Eight compounds were isolated from Oxytropis myriophylla. On the basis of spectral analyses, their structures were elucidated to be (6R,9R)-roseoside (1), (6R,9S)-roseoside (2), adenosine (3), myriophylloside B (4), myriophylloside C (5), myriophylloside D (6), myriophylloside E (7), and myriophylloside F (8). Five flavonoids (4-8) were new compounds, and the three known compounds were isolated from this plant for the first time.
