Abstract

The invention relates to a method for optimizing supercritical extraction of high-purity fennel essential oil based on a response surface method. The method comprises: using fennel seeds as raw materials; removing impurities from medicinal materials, crushing and sieving the medicinal materials, performing Box-Behnken design by using DesignExpert 8.0.6 software, optimizing a fennel essential oil supercritical extraction process according to a predicted value provided by the software, and extracting fennel essential oil by using a supercritical CO2 extraction method; carrying out qualitative and quantitative analysis on trans-anethole in the essential oil by utilizing GC/FID and GC/MS technologies; with the obtained essential oil yield comprehensive score as an index, the essential oil yield being 3-5%, the essential oil yield being two times higher than the volatile oil yield extracted by a steam distillation method, the content of trans-anethole reaches 90-95 mg/g, and identifying 45components after separation and identification by using a gas chromatography-mass spectrometry technology and account for 97.76% of the total components; wherein the terpenoids account for 5.64%, theoxygen-containing terpenoids account for 70.16%, and a series of volatile components which cannot be obtained by a traditional method are obtained in the aspect of components. A reference basis is provided for comprehensive evaluation, development and utilization of fennel essential oil extraction.

Description

technical field [0001] The invention relates to the technical field of plant component extraction, in particular to a method for optimizing supercritical extraction of high-purity cumin essential oil based on response surface method. Background technique [0002] Fennel, also known as Aripabadiyang, Cizeyana, Cizeyana, and Ciceyna, is the dry and mature fruit of fennel (Foeniculum vulgare Mill.), a commonly used medicinal material in traditional Chinese medicine. It is cultivated in Xinjiang, Gansu, Inner Mongolia, Shanxi, Shaanxi and Northeast China. [0003] Fennel is commonly used by food processors in medicine. It has the functions of invigorating the stomach, improving eyesight, and dredging collaterals. It is mainly used to treat poor appetite caused by excessive gastric juice, cold stomach and abdominal distension, nausea, hiccups, and brain deficiency and liver deficiency. Vision loss, urinary tract obstruction caused by kidney deficiency embolism. In addition to a...
