On the basis of the results of a spectral study of the products formed in the oxidation of gummosin and the reduction of the resulting ketone to an alcohol, it has been shown that the latter is not identical with farnesiferol A and has the substituent at C9 in the equatorial orientation. It has been shown that the transition from gummosin to farnesiferol A performed previously does not correspond to the facts.
