Abstract
The aerial parts of Osteospermum vaillantii (Decne) T. Norl., collected in Saudi Arabia, yielded four saponin glycosides, one of which was a new natural product. The structures of the isolated compounds were elucidated using MS, 1 H, 13 C NMR, 1 H- 1 H COSY, HMQC, HMBC and HOHAHA experiments.
