Article abstract of DOI:10.1016/S0031-9422(00)97089-4

Six new triterpene esters, iristectorenes A and C-G, along with one known one have been found in the seeds of Iris tectorum.On the basis of spectroscopic methods and chemical evidence, the esters were established to be 3-<3-hydroxy-2-<5-hydroxy-4,8,12-trimethyl-(3E,7E)-3,7,11-tridecatrienyl>-2,3-dimethyl-6-(1-methyl-2-oxoethylidene)cyclohexyl>propyl> (Z)-9-tetradecanoate, (Z)-11-hexadecanoate, (Z,Z)-9,12-octadecadienoate, hexadecanoate, (Z)-11-octadecenoate and octadecanoate, respectively.
