Embodiment 1

[0013] The preparation steps are as follows:

[0014] ⑴Material preparation: Remove impurities and crush 100g of dried wisteria flowers, pass through a 60-mesh sieve, and take the sieve to obtain a mixed powder;

[0015] (2) Extraction: Using supercritical extraction equipment, put the mixed powder into the extraction kettle of the supercritical CO2 extraction equipment, add ethanol with an entrainer content of 60% to immerse the mixed powder, use supercritical CO2 as the extraction solvent, and extract at a temperature of 30°C ~50°C, extraction pressure 15Mpa ~ 30Mpa, extraction time 4h ~ 6h, then use temperature rise and pressure drop to separate to form oil-water mixture, after cooling, the mixture will re-separate oil layer and water layer;

[0016] (3) Steam distillation: the mixture is placed in a steam distillation device and distilled by heating. After steam distillation, a white emulsion is obtained in a cone flask. The white emulsion composition is a mixture of rose...

Embodiment 2

[0019] ⑴Material preparation: Remove impurities and crush 150g of dried wisteria flowers, pass through a 60-mesh sieve, and take the sieve to obtain a mixed powder;

[0020] (2) Extraction: Using supercritical extraction equipment, put the mixed powder into the extraction kettle of the supercritical CO2 extraction equipment, add ethanol with an entrainer content of 60% to immerse the mixed powder, use supercritical CO2 as the extraction solvent, and extract at a temperature of 30°C ~50℃, extraction pressure 15Mpa~30Mpa, extraction time 4h~6h, and then use temperature rise and depressurization to separate to form oil-water mixture, after cooling, the mixture will re-separate oil layer and water layer; 

[0021] (3) Steam distillation: the mixture is placed in a steam distillation device and distilled by heating. After steam distillation, a white emulsion is obtained in a cone flask. The white emulsion composition is a mixture of rose oil and water;

[0022] ⑷ Filtration: When ...

Abstract

The invention discloses a preparation method of wisteria flower aromatic essential oil. The wisteria flower aromatic essential oil is prepared through extraction, separation and water absorption processes by refining; and supercritical carbon dioxide extraction is adopted to completely extract effective components of ingredients, so steps are simple, and the cost is saved, and compared with conventional methods, the method in the invention has the advantages of high extraction rate, low operating temperature, no damages to the effective components of a traditional Chinese medicine, no organicsolvent residual and simple process; and NaC is added to an emulsion in order to effectively separate oil and water, anhydrous NaSO4 can extract the water from the separated oil and water, and filtration is carried out to obtain the finished product, so the preparation method of wisteria flower aromatic essential oil has the advantages of simple refining process and high oil output, and is an ideal method for preparing the wisteria flower aromatic essential oil by the extraction, separation and water absorption processes.

Description

technical field [0001] The invention relates to the technical field of biological oil extraction, in particular to a preparation method of wisteria flower aromatic essential oil. Background technique [0002] Wisteria, also known as wisteria, Zhuteng, and Huanghuan. It belongs to Fabaceae and Wisteria, a large vine with deciduous climbing and twining properties. The dry skin is dark gray, not cracked; it blooms in spring, with a blue-purple butterfly-shaped corolla, and the flowers are purple or dark purple, very beautiful. Wisteria is a warm and temperate plant with strong adaptability to the growing environment. Produced in the Yellow River and Yangtze River Basin in the south of Hebei and Shaanxi, Henan, Guangxi, Guizhou, and Yunnan. Folk purple flowers are boiled in water or cold, or wrapped in dough and deep-fried to make "Purple Cake", "Purple Cake" and other flavored pasta. Wisteria aromatic essential oil has detoxification, antiemetic and diarrhea effects. The s...
