Fecha de publicación: | 28-abr-2021 | Editor: | Multidisciplinary Digital Publishing Institute | Citación: | Plants 10(5), 891: 1-14 (2021) | Resumen: | Three new compounds, the sesquiterpenes absilactone and hansonlactone and the acetophenone derivative ajenjol, have been isolated from a cultivated variety of Artemisia absinthium. In addition, the major lactone isolated, 3α-hydroxypelenolide, was biotransformed by the fungus Mucor plumbeus affording the corresponding 1β, 10α-epoxide. A cadinane derivative was formed by an acid rearrangement produced in the culture medium, but not by the enzymatic system of the fungus. Furthermore, 3α-hydroxypelenolide showed strong antifeedant effects against Leptinotarsa decemlineata and cytotoxic activity to Sf9 insect cells, while the biotransformed compounds showed antifeedant postingestive effects against Spodoptera littoralis | Versión del editor: | https://doi.org/10.3390/plants10050891 | URI: | http://hdl.handle.net/10261/240067 | DOI: | 10.3390/plants10050891 | E-ISSN: | 2223-7747 |
