Extraction method and application of sanchi flower hydrolat in high altitude area

Abstract

The invention belongs to the technical field of food and cosmetics, and discloses a method for extracting sanchi flower hydrolat in high-altitude areas, which comprises the following steps: (1) cleaning sanchi flowers, putting the sanchi flowers into a distillation kettle, adding deionized water, and crushing to obtain sanchi flower pulp; (2) adding deionized water containing magnesium chloride and ethylene diamine tetraacetic acid into the pseudo-ginseng flower pulp in the distillation kettle, and mixing; (3) heating the distillation kettle, keeping the boiling state, and distilling for 3-5 hours; and (4) when the temperature of the distillation kettle is reduced to 55 DEG C, opening a condenser, carrying out condensation separation to obtain distillate, and standing and filtering to obtain the sanchi flower hydrolat. The prepared sanchi flower hydrolat is free of any additive component, pleasant in fragrance, capable of retaining saponin and volatile oil components in sanchi flowers, capable of preserving moisture, supplementing water, improving skin quality, inhibiting melanin biosynthesis, moisturizing epidermis and repairing barriers, and capable of being applied to cosmetics. Meanwhile, the product has the effects of resisting inflammation, protecting the liver, reducing blood fat, reducing blood pressure, resisting tumors, relieving asthma and the like, and can be applied to food.

Description

technical field [0001] The invention belongs to the technical field of food and cosmetics, and relates to a method for extracting Sanqi flower hydrosol in high altitude areas and its application in food and cosmetics. Background technique [0002] Panax notoginseng is the dry product of Panax notoginseng, which has grown for more than 2 years and has not yet opened inflorescences. The main active ingredients are saponins, including ginsenosides Rb1, Rb2, Rb3, Rc, and Panax notoginsenoside Fc. There are a variety of volatile oil components, mainly including monoterpenoids such as camphor, borneol, and sesquiterpenoids such as δ-pijnasolene, δ-bourbonene, δ-syringene, β-picubaene, other Aromatic terpenes, etc., have the effects of sedation, anti-inflammatory, liver protection, lowering blood fat, lowering blood pressure, anti-tumor, relieving asthma, antitussive, and expectorant. [0003] Pure dew refers to a 100% saturated distilled stock solution separated during the distil...

AI Technical Summary

Problems solved by technology

At high altitudes, the air is relatively thin, and the natural atmospheric pressure is low. The lower the air pressure, the lower the boiling point. Using traditional methods to extract pure dew will affect the extraction content of its main components and directly affect the aroma of the pure dew.

[0005] Since Panax notoginseng mostly grows in high-altitude areas such as Yunnan, the boiling point of the solution is low. Using traditional distillation methods, the extraction rate of pure dew is relatively lower than that in plain areas, resulting in low content of Panax notoginseng essential oil, and the extracted Panax notoginseng flower hydrosol has a weak fragrance

There are relatively few reports about the extraction of Panax notoginseng pure dew at present. The inventors have found through experimental research that adding extraction aids in the extraction process of panax notoginseng pure dew can effectively improve the content of essential oils; Sodium chloride increases the yield of pure dew. Although the yield is increased, high-salinity wastewater will be formed during the extraction process. Direct discharge will reduce the dissolved oxygen in the water, destroy the living environment of phytoplankton and animals in the water, and cause environmental pollution.
