title: Chemical diversity of iridal-type triterpenes in Iris delavayi collected in Yunnan Province of China.
abstract: From Iris delavayi collected in the northwestern Yunnan Province of China, eight iridal-type triterpenoids were isolated, three of which were new. Both 2(7)Z- and 2(7)E-iridals were isolated in about equal amounts from the sample collected at Laojunshan, while only 2(7)Z-iridals were isolated from samples collected in Shangrila area, indicating the presence of chemical diversity in the species.
