Diterpenes and umbelliferone derivatives from Haplopappus deserticola
Phytochemistry, 1990 Abstract The aerial parts of Haplopappus deserticola afforded three ent -labdane and one labdane derivative as well as a nor - ent -labdane. Furthermore, in addition to three known umbelliferone derivatives, a dimeric coumarin was isolated. The structures were elucidated by high field 1 H NMR spectroscopy.
