Bioactive compounds from transformed root cultures and aerial parts of Bethencourtia hermosae

A study of Bethencourtia hermosae, aerial parts and root cultures, afforded the undescribed sesquiterpenes ceratopicanol angelate, 8β-hydroxy-african-4(5)-en-3-one tiglate, 8β-hydroxy-african-4(5)-en-3-one 3′-angeloxy-2′-methylbutanoate, 1α,8β-dihydroxy-african-4(5)-en-3-one 8β-angelate, 6α,8β-dihydroxy-african-4(5)-en-3-one8β-angelate (8), and the alkaloid hermosine. Their insect antifeedant and cytotoxic activities were also studied.46
