Pentacyclic triterpene and alkane side chain skeletons are commonly found in holostane type glycosides. (a) Pentacylic triterpene skeletons. Substitution by selective functional groups and unsaturation generally take place in the alkane side chain (2-methylpentane) attached to C-20 of the E-ring of aglycone; (b) Alkane side chain architectures.
