Polypodium vulgare L.

Osladin, a steroidal saponin, was isolated as a sweet principle of the fem Polypodium vulgare L. (Polypodiaceae). Later, Nishizawa and Yamada.36 reinvestigated the structure of osladin and revised the stereochemistry at C-22, C-25, and C-26. Although osladin has been reported to be 3000 times sweeter than sucrose, this value was also... 

The steroidal saponin osladin (58) was isolated as a sweet principle from the fern Polypodium vulgare L. (Polypodiaceae) nearly 40 years ago [20,28]. However, the original structure proposed was later revised because the synthetic compound produced was not sweet at all [87]. The correct structure of osladin (58) was characterized by single crystal X-ray...
