The Chemical Composition of Essential Oils from Cinnamomum camphora and Their Insecticidal Activity against the Stored Product Pests.
To investigate the chemical composition and insecticidal activity of the essential oils of certain Chinese medicinal herbs and spices, the essential oils were extracted from the stem barks, leaves, and fruits ofCinnamomum camphora(L.) Presl, which were found to possess strong fumigant toxicity againstTribolium castaneumandLasioderma serricorneadults. The essential oils of the plants were extracted by the method of steam distillation using a Clavenger apparatus. Their composition was determined by gas chromatography/mass spectrometric (GC-MS) analyses (HP-5MS column), and their insecticidal activity was measured by seal-spaced fumigation. D-camphor (51.3%), 1,8-cineole (4.3%), and α-terpineol (3.8%), while D-camphor (28.1%), linalool (22.9%), and 1,8-cineole (5.3%) were the main constituents of its fruits. The essential oils of theC. camphoraall showed fumigant and contact toxicity. Other compounds exhibited various levels of bioactivities. The results indicate that the essential oils ofC. camphoraand its individual compounds can be considered a natural resource for the two stored-product insect management.
