栀子花精油的水蒸气蒸馏提取工艺

Extraction process of Gardenia jasminoides essential oil by steam distillation

  • 摘要: 栀子花精油是一种具有芳香和药用价值的天然产物。用水蒸气蒸馏法对栀子花精油进行提取,以栀子花精油提取量为指标,通过单因素试验和正交试验考察原料润湿与否、蒸馏温度、提取时间、装填料厚度对精油提取量的影响,确定水蒸气蒸馏提取栀子花精油的最佳工艺。结果表明,原料预润湿,蒸馏温度105℃,提取时间240 min,装填料厚度为4 kg(75.49 mm)时,栀子花精油提取量最大,平均提取量为95.04±0.22 mg·kg−1。这为栀子花精油的工业化生产提供了依据。

     

    Abstract: Gardenia jasminoides essential oil is a natural product with aromatic and medicinal properties.The Gardenia jasminoides essential oil was extracted using the steam distillation method. Using the extraction amount of Gardenia jasminoides essential oil as an indicator, the effects of raw material wetting, distillation temperature, extraction time, and filling thickness on the extraction amount of essential oil were investigated through single-factor experiments and orthogonal experiments. The optimal process for extracting G. jasminoides essential oil by steam distillation was determined. The results indicated that the maximum extraction amount of G. jasminoides essential oil, with an averageextraction amount of 95.04±0.22 mg·kg−1, was achieved when the raw material was pre-wetted, the distillation temperature was set at 105 °C, the extraction time was 240 minutes, and the filling thickness was 4 kg(75.49 mm). This provides a basis for the industrial production of gardenia essential oil.
