Embodiment 1

[0015] Using the flowers of unisexual magnolia as raw material, it is extracted by steam distillation. Weigh 100g of flowers and place them in a 1000mL round bottom flask, add 400mL of distilled water to soak for 1h, and extract in a steam distillation pot under normal pressure at 120°C for 6h, collect the oil layer in the oil-water separator, dry and dehydrate with anhydrous sodium sulfate, and obtain Fragrant yellowish transparent unisexual magnolia essential oil with an extraction rate of 0.13%.

Embodiment 2

[0017] The flower of unisexual magnolia is used as raw material, and the organic solvent is extracted at room temperature. Put 30 g of parthenotropic magnolia in a 500 mL conical flask, add 120 mL of petroleum ether, extract at room temperature for 3 h, and filter to obtain a solution, heat the solution under normal pressure to recover petroleum ether, and obtain a parthenotropic magnolia paste, which is passed through Dissolve in ethanol, filter, and freeze for 24 hours to remove the precipitate, and recover the ethanol by rotary evaporation under reduced pressure to obtain the light yellow transparent unisexual magnolia essential oil with a special aroma, and the extraction rate is 0.24%.

Embodiment 3

[0019] The flower of unisexual magnolia is used as raw material, and the organic solvent reflux extraction method is adopted. Put 30g of unisexual magnolia flower in a 500mL Erlenmeyer flask, add 120mL of petroleum ether, heat and reflux in a reflux device for extraction for 4h, filter to obtain a solution, heat the solution under normal pressure to recover petroleum ether, and obtain a parthenotropic magnolia flower paste, ointment The substance was dissolved in ethanol, filtered, refrigerated for 24 hours to remove the precipitate, and the ethanol was recovered by rotary evaporation under reduced pressure to obtain the brown-yellow transparent monosexual magnolia essential oil with an aromatic smell, and the extraction rate was 0.22%.

[0020] Get the parthenosexual magnolia spice essential oil extracted from the above examples for component analysis, dilute the essential oil with absolute ethanol at a ratio of 1:1, take 0.2 μL of the diluted oil sample, and measure and analy...

Description

technical field [0001] The invention belongs to the field of research and development of natural spices, in particular to a spice essential oil extracted from unisexual magnolia flowers and a preparation method thereof. Background technique [0002] The unisexual magnolia (Kmeria septentrionalis), also known as Xirui magnolia and Huanyong wood, belongs to the genus Kmeria septentrionalis in the family Magnoliaceae. It has unisexual flowers and dioecious plants. It is a rare and endangered plant unique to my country. The unisexual magnolia is only distributed in Guangxi and Guizhou, and has been listed as a first-class protected plant in my country. The tree is fast growing, fine material and tough. Pollination of unisexual magnolia is affected by flowering phenology and pollinators, resulting in low seed setting rate. Germination is difficult due to the oil in the outer testa, and the plant resources are on the verge of extinction due to people's wanton logging. In recent ...
