## Abstract Hydroxyiridals − monocyclic triterpenoids − are found abundantly in sword lilies. They feature a homofarnesyl side chain that is hydroxylated at one of the allylic methylene groups, which gives rise to a chiral carbon atom. The absolute configuration of six hydroxyiridals from different
