title: Enolic iridolactone and other iridoids from Alberta magna.
abstract: From fresh leaves of Alberta magna two new iridoids and a known cyclopentene dialdehyde have been identified. One of the new compounds has the less-common irido-lactone structure and has an enolic hydrogen on C-4. Two of the compounds show short term mosquito-repellent effects.
