Description
Technical field
The technical program belongs to natural plant essential oils extractive technique field, in particular to a kind of agilawood essential oil extracting process.
Background technique
Essential oil is the general name in plant with certain volatile oily ingredient, has more biomedical active,
Such as anti-inflammatory, analgesia, tranquilizing the mind, expelling parasite, degerming, skin care, sweating promote and protect to the normal physiological activity for improving human body
Immune system has great importance.Research has shown that different essential oils are for endocrine, metabolism, gynecological disease, nervous system
There is good curative effect with the disease of digestive system etc..
Agalloch eaglewood be winter daphne can the resiniferous timber of plant suspension culture of Aquilaria sinensis, be the kind that " Chinese Pharmacopoeia " is included, be clinically often
Qi-regulating drug.Its acrid flavour, hardship, warm-natured, returns spleen, stomach, kidney channel have the function of that sending down abnormally ascending, middle benefit gas, warm kidney is supporing yang.
Agalloch eaglewood is that the timber containing resin is formed after many years deposition, and agalloch eaglewood is exactly very rare since ancient times
Timber is also the superior raw material of craftwork.Agalloch eaglewood is that agalloch eaglewood trunk is parasitic by fungi intrusion, is changed, heavy through many years
Product formed face cream, be with drive it is dirty avoid evil spirits, adjust in calming the liver effect valuable ingredient of traditional Chinese medicine, be very rare.
Different from santal, agalloch eaglewood is not a kind of timber, but what a kind of special fragrant tree " knot " went out, it is mixed with grease
The solid-state condensation product of (resin) ingredient.And the timber of this kind of fragrant tree itself has no special fragrance, and wooden more soft.According to
Research, several trees that Thymelaeceae agalloch eaglewood belongs to, such as Aguilaria malaccensis Lamk tree, tabernaemontanus bulrush perfume (or spice) tree, Aquilaria agallocha tree can form agalloch eaglewood.One
As for, the density of agalloch eaglewood is bigger, illustrate cohesion resin it is more, quality is also better.
Agalloch eaglewood is the resiniferous part of Thymelaeceae agalloch eaglewood category suspension culture of Aquilaria sinensis, in China mainly produced in Hainan, Guangdong, Yunnan, good fortune
It builds etc. and to save.Its key aroma ingredient is sequiterpene and its containing oxygen derivative, aromatic compound, fatty acid and its lipid and chromogen
Ketone.Agalloch eaglewood is that the remaining white wooden being connected with agalloch eaglewood after face cream is rejected at agalloch eaglewood Edgeworthia chrysantha, wherein containing few
The face cream of amount, therefore agalloch eaglewood is expensive.
Agilawood essential oil, that is, agalloch eaglewood extractive of volatile oil, the existing method for extracting agilawood essential oil is more, there is steam distillation
Method, supercritical extraction, solvent method and mixed enzyme fermentation extraction method etc., but these extracting methods to the extraction efficiency of agalloch eaglewood all
Be not it is very high, be easy to cause the waste of raw material.
Summary of the invention
The technical program provides a kind of agilawood essential oil extracting process, and the extraction efficiency of the extracting process is high, and can fill
