| Popis: | 5 pages, figures, and tables statistics. In the context of the study on plant defensive compounds we have isolated the main alkaloid from Hippeastrum puniceum (Amaryllidaceae), 3-0-acetyl-narcissidine. and its biological activities tested against two divergent insect species and severalplant species, was isolated from to bioactive alkaloidal fraction of H. puniceum. Its chemical structure was established by spectroscopic analysis. The biological activity test showed that is an antifeedant against the polyphagous insect. Spodoptera littoralis but not against the olyphage Lepinotarsa decemlineata. Furthermore. the root growth of Amaranthus hypochondriacus. Rottboellia cochinchinensis. Panicum maximum and Solanum Icypersicum was significantly affected by These results a plant protective role for H. puniceum alkaloids. |
