| 摘要 | [Objectives] To explore the extraction conditions of essential oil from eucalyptus leaves. [Methods] The essential oil of eucalyptus leaves was extracted by steam distillation, and the yields of essential oil from eucalyptus leaves under different extraction times, soaking times and different solid-liquid ratios were analyzed through orthogonal test with three factors and three variables. [Results] The effects of various factors on extraction results were: distillation time >solid-liquid ratio>soaking time. When the extraction time and soaking time were 1.5 and 2 h, and the solid-liquid ratio of eucalyptus leaves to distilled water was 1：10, the yield of essential oil was the highest (0.8%). The yield of essential oil increased with the increase of extraction and soaking time, but when reaching the optimal value, the yield decreased with the extension of time. Increasing the solid-liquid ratio can improve the yield of essential oil, but beyond a certain value the yield increased gradually while the cost performance decreased. [Conclusions] The results will provide some reference for the recovery and utilization of eucalyptus leaves. |
