Chemical composition and insecticidal activity of the essential oil of Amethystea caerulea L.
Summary of "Chemical composition and insecticidal activity of the essential oil of Amethystea caerulea L."
The essential oil of the aerial parts of Amethystea caerulea L. was obtained from steam distillation and investigated by GC and GC-MS. The main components of the essential oil were morrilol (25.1%), 4-vinylguaiacol (14.3%) and acetoanisole (14.3%), followed by linalool (6.6%), eugenol (5.8%) and α-caryophyllene (5.2%). The essential oil showed pronounced contact toxicity against Drosophila melanogaster L. and maize weevil, Sitophilus zeamais (Motsch.), with LD(50) values of 5.18 and 50.45 µg per adult, respectively. The essential oil also possessed strong fumigant toxicity against the maize weevils with an LC(50) value of 25.39 µg mL(-1).

Medical and Biotech [MESH] Definitions
Kalanchoe
A plant genus of the family CRASSULACEAE. Members contain bryophyllins (also called bryotoxins) which are bufadienolides (BUFANOLIDES) that have insecticidal activity.
Models, Chemical
Theoretical representations that simulate the behavior or activity of chemical processes or phenomena; includes the use of mathematical equations, computers, and other electronic equipment.
Electrochemistry
The study of chemical changes resulting from electrical action and electrical activity resulting from chemical changes.
Isochores
Large regions of the GENOME that contain local similarities in BASE COMPOSITION.
Base Composition
The relative amounts of the PURINES and PYRIMIDINES in a nucleic acid.
