Cauloside b has been identified as hederagenin 3- -L-rhamnopyranosyl-(1 2)- -L-arabinopyranoside, while cauloside c has the structure of hederagenin 3-0- -L-arabinopyranosyl(1 3)- -L-pyranosyl-(1 2)- -L-arabinopyranoside.Pacific Ocean Institute of Bioorganic Chemistry, Far Eastern Scientific Center of the Academy of Sciences of the USSR, Vladivostok.
