A new triterpenoid, (20R)-20,25-epoxy-3-methyldammaran-2-en-6α,12β-diol (1), has been isolated from the flowers of Lilium speciosum var. gloriosoides Baker, along with four known triterpenes, (20R)-20,25-epoxy-dammaran-2-en-6α,12β-diol (2), isodahurinol (3), 12β-hydrocimigenol (4), and oleanolic acid (5), which were reported for the first time from this plant. Their structures were elucidated on the basis of spectroscopic methods and from literature values. All components were tested for antivirus activity.
