Two new diterpenes,2-acetoxy-13-hydroxy-mulin-11-ene and 2-acetoxy-mulin-11, 13-diene,have been isolated from the aerial parts of Azorella spinosa and their structures determined by spectroscopic and conventional chemical ...

The inhibition of the enzyme acetylcholinesterase is considered as a strategy for the treatment of Alzheimer's disease, senile dementia, ataxia, and myasthenia gravis. Three lanostane- and two cycloartane-type triterpenes, ...

The absolute configuration of the diterpenoid 9,12-cyclomulin-13-ol (1), a constituent of Azorella and Laretia species, has been established by vibrational circular dichroism spectroscopy in combination with density ...

In addition to mulinolic acid, a new diterpenoid, mulin-11,13-dien-20- oic acid, has been isolated from the aerial parts of Azorella compacta. Its structure was based on a spectroscopic comparison with mulinolic acid and ...

Four isoflavones, isolated from the whole plant of Azorella madreporica, were identified as angustone C (1), alpinumisoflavone (2), licoisoflavone A (3) and isolupalbigenin (4) by spectroscopic studies. The compounds were ...

A new diterpenoid, azorellanol (5), was isolated from the whole plant of Azorella compacta (Umbelliferae). The stricture was established by using mainly one- and two-dimensional NMR techniques, whereas the absolute ...

A new azorellane diterpenoid has been isolated and identified from the aerial parts of Azorella madreporica Clos. The structure of 1 was established by one- and two-dimensional NMR techniques. © 2011 Taylor & Francis.
