Structures and stereochemistry of melicophyllone A and hypocholesterolemic melicophyllone B, novel sesquiterpene lactones from Melicope triphylla
Abstract
Melicophyllones A and B, two novel skeletal sesquiterpene lactones, have been isolated from Melicope triphylla and their structures have been established from spectral data in conjunction with single-crystal X-ray analyses; melicophyllone B demonstrated significant hypocholesterolemic activity.
