Resumo: Croton L. belongs to the Euphorbiaceae family, found in the Caatinga biome of northeastern Brazil. The study evaluated the influence of the circadian cycle and of seasonality on yield, and the chemical composition of essential oils of Croton blanchetianus Baill., Croton nepetifolius Baill. and Croton zehntneri Pax & K.Hoff m. To study the circadian cycle, the leaves were collected at 8:00, 12:00 and 20:00 and for the seasonal collections they were carried out at 8h. The circadian cycle and seasonality only infl uenced the yield of C. zehntneri, indicating a greater yield in harvest at 12:00 and in the dry season. Chemical compositions of C. blanchetianus, C. nepetifolius and C. zehntneri oils were influenced by the circadian cycle and seasonality demonstrating that certain compounds are only produced at specific times and seasons. Therefore, the studied environmental factors affect the yield and chemical composition of essential oils of species of Croton.

O estudo objetivou avaliar a influência do ciclo circadiano e da sazonalidade no rendimento e na composição química dos óleos essenciais de Croton blanchetianus Baill., Croton nepetifolius Baill. e Croton zehntneri Pax & K. Hoff m. Para estudo do ciclo circadiano, as folhas foram coletadas no horário de 8, 12 e 20h e para a sazonalidade as coletas foram realizadas no horário de 8h. O ciclo circadiano e a sazonalidade influenciaram o rendimento apenas de C. zehntneri, indicando maior rendimento na colheita às 12 horas e na estação seca. A composição química das espécies estudadas foi influenciada pelo ciclo circadiano e a sazonalidade, constatando-se que determinados compostos só são produzidos em horários e estações específicas. Portanto, os fatores ambientais estudados interferem no rendimento e composição química dos óleos essenciais das espécies de Croton spp.Iheringia.
