Ruzicka and his school, a large majority of the well-characterized triterpenoid compounds have been classified as being related to one or other of the three isomeric alcohols, α-amyrin, β-amyrin or lupeol, and their relationships with these three parent compounds have been rigorously established1. Such a grouping is also indicated by the results of studies of molecular rotation differences2.
