Osladine is a naturally occurring, high-intensity sweetener isolated from the rhizome of Polypodium vulgare.[3] It is a saponin, sapogenin steroid glycoside, 500 times sweeter than sucrose.[4]
A related compound, polypodoside A, has been identified from the of Polypodium glycyrrhiza and is 600 times sweeter than a sucrose solution at 6%.[2]
