kaur-16-en-18-oic acid, 13-hydroxy-
aglucon of stevioside. Isol. from Cucurbita maxima Rebaudioside B, D, and E may also be present in minute quantities; however, it is suspected that rebaudioside B is a byproduct of the isolation technique. The two majority compounds stevioside and rebaudioside, primarily responsible for the sweet taste of stevia leaves, were first isolated by two French chemists in 1931.
