At present, in natural plant spices extracting method, the most frequently used method is steam distillation.The equipment that is characterized in is simple, processing ease, cost is low, output is large.Except the plant material that the main note composition easily dissolves, is hydrolyzed or decomposes in boiling water (as jasmine, violet, Acacia, jacinthe etc.), most scented plants can adopt steam distilled method to extract essential oil.Traditional essential oil production method has milling process, steam distillation and organic solvent extraction, and wherein steam distillation is the classical way of traditional mode of production essential oil product.Adopt steam distillation to extract outward appearance, the color and luster of the Herba Lysimachiae foenumgraeci quintessence oil obtained, fragrance is good, and refractive index etc. are all in the GB scope.Because steam distillation itself has advantages of, obtain the Herba Lysimachiae foenumgraeci quintessence oil quality better, so have dissemination in industrial production in addition.
Summary of the invention
The invention provides the Herba Lysimachiae foenumgraeci quintessence oil extracting method, adopt vapor distillation method, the oil extracted has the effects such as calmness, sterilization, treatment and health care.
The present invention adopts following technical scheme: the Herba Lysimachiae foenumgraeci quintessence oil extracting method, and extraction step is as follows:
(1) the lavandula angustifolia dried flower is weighed;
(2) dried flower is put into water, and dried flower is soaked for the 1:8-10 ratio with the quality ratio;
(3) soaked flower is packed in distiller;
(4) vapor distillation extracts: by above-mentioned soaked the spending of steam injection, make soaked flower be subject to thermal evaporation, and collect vaporised gas cooling, obtain extracting solution No. one time;
(5) secondary separation: not thorough because of flash liberation, may there is the oil mixing with water phenomenon, its secondary separation is obtained to essential oil;
(6) pure essential oil separation obtained is weighed;
(7) pure essential oil packing is preserved.
Advantage of the present invention: when using the vapor distillation method extraction and manufacturing essential oil, put into distiller to vegetable material, then in the steam injection vegetable material.Needn't add water in this method distiller, the water vapour that boiler is occurred passes into bottom in distiller, and generally under porous barrier, the pot bottom position is equipped with one and is had and permitted lacunary ring pipe, and water vapour directly sprays by aperture, through porous sieve plate, directly enters the bed of material.Usually, the water vapour of being sent here by boiler be there is certain pressure, temperature is higher and saturated steam that water capacity is lower can make rapidly material bed intensification.The steam of heat contributes to discharge aromatic molecules from vegetable material because steam can the force open vegetable material in the oil droplet cell of essential oil storage.These volatile essential oil molecules discharge and enter among steam from vegetable material.The temperature of steam needs careful regulation and control, makes it just to make vegetable material discharge essential oil.Vegetable material or essential oil are lighted in too hot meeting.The steam that contains essential oil is by a cooling system, and steam is concentrated, forms liquid, and essential oil and water just have been separated from each other out like this.It is large that the vapour pressure ratio normal atmosphere used is wanted, so the boiling temperature of steam while producing can promote that more than 100 ℃ essential oil discharges fast from vegetable material like this, prevents that essential oil is damaged.Herba Lysimachiae foenumgraeci quintessence oil is responsive to heat.Adopt this extracting method, essential oil just can not be damaged, and its composition can not resolve into phantol (Linaool, phantol) and acetic acid yet, as fragrant camphor tree ester etc.
The material quantity that this kind of distillation mode distilled is more, and hydrolytic action is little, and efficiency is high.Be suitable for scale operation.Steam distilled distillation speed is fast, and because dried flower soaks in advance outside pot, fully " water is loose ", fuel-displaced also fast.The present invention has done certain exploration for the extraction process of optimizing Herba Lysimachiae foenumgraeci quintessence oil, and the essential oil extracted meets national standard, has the effects such as calmness, sterilization, treatment and health care.Contribute to improve the level of utilizing of corresponding plants resource, promote the development of China's scented plants industry, serve society.
