Embodiment 1

[0011] Weigh 1000g of dry magnolia, wash and dry, pulverize with a pulverizer, then put it into the extraction tank of supercritical extraction equipment, extract with supercritical carbon dioxide under the conditions of 15MPa and 40°C, and concentrate under reduced pressure to obtain magnolia volatile oil 23.7 g.

[0012] The chemical composition of Magnolia magnolii extract was analyzed by GC / MS. A total of 49 compounds were identified, 29 of which were identified, accounting for about 88% of the chromatographic peak area. Among the components identified, the content of eucalyptol is the largest, about 19%, and the remaining volatile oil components with large content are 13.9% of ylang-ylang oil and 11.2% of farnesol.

Abstract

The invention relates to a method for extracting essential oil from a magnolia flower, and belongs to fields of food additives, in particular to essential oil and a preparation method thereof. The method comprises the following steps: washing and drying a magnolia flower material, crushing the magnolia flower material through a crusher, loading the magnolia flower material into an extraction pot of supercritical extraction equipment, performing supercritical carbon dioxide extraction under the pressure of 15 MPa and at 40 DEG C, performing vacuum concentration, and then obtaining the essential oil extracted from the magnolia flower. The method ensures that product yield of the essential oil is 2.37%, and has the characteristics of rapidness, safety, simple technology, high operability, high product yield, high quality and the like.

Description

technical field [0001] The invention relates to a method for extracting essential oil from Magnolia magnolia, belonging to the field of food additives, especially essential oil and its preparation method. Background technique [0002] Xinyi is the dried flower bud of Wangchunhua, Magnolia or Wudang Magnolia of Magnoliaceae, produced in Sichuan, Hubei, Hunan, Hebei, Henan, Shaanxi, Gansu and other places, and Henan is the main producing area. Magnolia magnolia is not only a precious Chinese medicinal material, it has the functions of dispelling wind and cold and dredging the nasal orifice, and is used for wind-cold headache, nasal congestion, sinusitis, and runny nose; it is also a good fragrance raw material, and the extracted essential oil can be used as food flavor , Production of tobacco flavor and daily chemical flavor. The medicinal and aromatic active ingredients of Magnolia magnolia are all volatile oils contained in it. Because of its volatile characteristics, tradi...
