Five new oleanane saponins (1-5) together with four know flavonol glycosides were isolated from the aerial parts of
Stylosanthes erecta. Their structures were elucidated by 1D and 2D NMR experiments including 1D-TOCSY, DQFCOSY,
ROESY, HSQC, and HMBC spectroscopy, as well as ESIMS analysis. The aglycone moieties of 1-4 were
assigned as new oleanane derivatives.
