Biosynthesis of the bufadienolide ring of scillirosid in Scilla maritima

L R Galagovsky et al. Z Naturforsch C Biosci. 1984 Jan-Feb.

Abstract

Administration of sodium [1,2-14C2]oxaloacetate and sodium [1-14C]acetate to Scilla maritima plants yielded labelled scillirosid. A systematic degradation of scillirosid indicated that the alpha-pyrone ring of the bufadienolide is formed by the condensation of a pregnane derivative (derived from mevalonic acid via squalene) and one molecule of oxaloacetic acid.
