| Sumario: | The objective of this study was to establish the chromatographic fingerprints of the essential oil (EO) from <i>Stellera chamaejasme</i> flowers collected from various natural sites by gas chromatography (GC) combined with chemometric methods. The EO was obtained by hydrodistillation, and its chemical composition was analyzed by gas chromatography−mass spectrometry (GC−MS). Most components were identified as ketones and the relatively high-content components were fitone (38.973%), <i>n</i>-hentriacontane (5.807%), myristic acid (4.944%) and phytol (3.988%). In addition, the repellent activities of the EO from <i>S. chamaejasme</i> flowers and its four main chemical compounds were evaluated against three stored product pests (<i>Tribolium castaneum</i>, <i>Lasioderma serricorne</i>, <i>Liposcelis bostrychophila</i>) for the first time. In this work, the EO and the four chemical compounds showed a repellent effect against three storage pests after 2 and 4 h exposure. The experimental method and repellent activity of <i>S. chamaejasme</i> flower EO could provide a basis for the development of botanical pesticide and the utilization of the rich plant resources of <i>S. chamaejasme</i> in the future. |
