Abstract
The invention discloses a kind of preparation methods of wistaria flower volatile oil, prepare wistaria flower volatile oil by extraction, separation, water suction technique using refining；Component effective component can be extracted completely using supercritical carbon dioxide extracting, step is simple, cost has been saved, has been compared with the traditional method simultaneously, has had the advantages that recovery rate height, low operation temperature, effective component of chinese medicine are not destroyed, organic solvent-free remains and simple process；NaC is added in emulsion in the present invention simultaneously, it can more effectively oil-water separation, along with anhydrous Na SO4 can absorb water the grease after separation, it is got product after filtering, it is simple with refining technique, advantage more than oil pump capacity is the preparation method that wistaria flower volatile oil is preferably prepared using extraction, separation, water suction technique.
Description
Technical field
The present invention relates to the technical field of biological oil extraction, espespecially a kind of preparation method of wistaria flower volatile oil.
Background technique
Chinese wistaria, alias Chinese wistaria, Zhu Teng, Huang Huan.Belong to pulse family, Wistaria, a kind of fallen leaves climb up by holding on to the big liana of prehensile.It is dry
Skin Dark grey, does not split；Spring blooms, the livid purple color crown of papilionaceous flower, flower purple or darkviolet, very beautiful.Chinese wistaria is warm band and temperature
Band plant, to the adaptable of growing environment.Produce the Yellow River Yangtze river basin and Shaanxi, Henan, Guangxi, Guizhou, Yunnan on the south Hebei.
Civil purple flower or water are scalded cold and dressed with sauce, or wrap up in face frying, production " purple trailing plants cake ", the flavors wheaten food such as " purple trailing plants cake ".And Chinese wistaria is fragrant
Essential oil has removing toxic substances, antiemetic to rush down and other effects.The seed of Chinese wistaria is slightly poisonous, and containing cyanide, the volatile oil of refinement can be controlled
Muscles and bones pain, moreover it is possible to prevent wine corruption rotten.Chinese wistaria leatherware has desinsection, analgesic, dispelling wind and removing obstruction in the meridians and other effects, can control muscles and bones pain, wandering arthritis pain,
Enterobiasis etc..Traditional local method refines wistaria flower volatile oil, and it is cumbersome that there is refining techniques, the few defect of oil pump capacity, to purple
Rattan refines volatile oil and brings many shortcomings.
Summary of the invention
The purpose of the present invention is to provide the preparation methods that wistaria flower volatile oil is refined in a kind of extraction, to solve above-mentioned back
The problem of being proposed in scape technology.
To achieve the goals above, case is put in technology of the invention solution is: a kind of preparation method of wistaria flower volatile oil,
Wistaria flower volatile oil is prepared by extraction, separation, water suction technique using refining；Its component:
| Parts by weight | |
| Dry wistaria flower | 100g~150g |
| NaCl | 60g~80g |
| NaSO4 | 20g~40g |
Preparation step is as follows:
(1) stock up: dry wistaria flower being cleaned and is crushed, cross 60 meshes, extracting screen underflow obtains mixed powder；
(2) extract: using supercritical extracting equipment device, mixed powder is put into the extraction kettle of SCF-CO 2 equipment, is added
Enter to carry secretly the ethyl alcohol that agent content is 60% and submerges mixed powder, using supercritical CO 2 as extractant, extraction temperature 30 DEG C~50
DEG C, extracting pressure 15Mpa~30Mpa, extraction time is 4h~6h, is then separated using heating, decompression, forms grease
Mixture, after cooling, mixture can separate oil-yielding stratum and water layer again again；
(3) steam distillation: mixture is placed in steam distillation device, is distilled by heating, after steam distillation, vertebra
The emulsion of white is obtained in shape bottle.The emulsion component of white is the mixture of attar of rose and water；
(4) filter: when attar of rose and water are separated, NaCl need to be added into emulsion, with its concentration is increased, just will appear obvious
Layering, then this two layers point is opened with separatory funnel.Isolated oil reservoir contains certain moisture, and some anhydrous Na SO4 need to be added
Water suction, stands overnight, and refilters and removes solid Na2SO4, wistaria flower volatile oil can be obtained.
The present invention can be extracted completely component effective component using supercritical carbon dioxide extracting, and step is simple, section
About cost, is compared with the traditional method simultaneously, there is recovery rate height, low operation temperature, effective component of chinese medicine not to be destroyed, nothing has
The advantages of solvent residual and simple process；It is obvious in emulsion NaC layering to be added in the present invention simultaneously, can promote more effectively into
The separation of row grease can obtain in addition the grease after separation effectively can be carried out moisture absorption by anhydrous Na SO4 after filtering
Finished product has refining technique simple, the advantage more than oil pump capacity, is ideal using extraction, separation, water suction technique preparation wistaria flower
The preparation method of volatile oil.
