Description
Technical field
The present invention relates to a kind of method of plant component extraction, in particular to a kind of subcritical abstraction fresh peony flower medicinal extract
Method.
Background technique
Fresh flower medicinal extract is exactly that will immerse in organic solvent containing the fresh flower of aromatic oil, using transport phenomenon, make aromatic substance,
Protein, pigment etc. are transferred in organic solvent, then different with aromatic substance boiling point using organic solvent, will with distillating method
Organic solvent recycling is clean, and gained is exactly fresh flower medicinal extract like aromatic substance paste.Fresh peony flower medicinal extract can be used as good
The raw material of cosmetics.105820880 A of China Patent Publication No. CN publication date on 08 03rd, 2016, discloses a kind of low temperature
The method of fresh peony flower medicinal extract and fresh peony flower water in abstracting tree peony fresh flower stoste, used raw material are fresh peony flower stoste,
It needs peony carrying out pre-processing, obtains fresh peony flower stoste, then carry out fresh peony flower by raw material of fresh peony flower stoste
The extraction of medicinal extract, and the subsequent treatment process that the water in fresh peony flower stoste makes is complicated, to increase cost.
Summary of the invention
In order to make up the above deficiency, a kind of method that the present invention discloses subcritical abstraction fresh peony flower medicinal extract, simple process,
It is low in cost.
The present invention is achieved through the following technical solutions：A kind of method of subcritical abstraction fresh peony flower medicinal extract, including
Following steps：
（1）Fresh flower picking：4 ~ 8 points of tree peonies opened are selected, plucking time selects the morning, and when picking wears disposable glove, picks
It is packed into the refrigerated vehicle that temperature is 0 ~ 10 DEG C immediately afterwards；
（2）Extraction：Fresh flower is put into extractor, is vacuumized, so that pressure is -0.085MPa ~ -0.09 in extractor
MPa is extracted using No. 4 solvents, the mass ratio 30 ~ 35 of extractant and fresh flower：4, extraction temperature is 30 ~ 45 DEG C, pressure 1
~ 15MPa, extraction time are 20 ~ 60min, repeat extraction 2 ~ 3 times, after extraction, stratification obtains miscella phase and flower
Slag phase；
（3）Product treatment and extractant recycle：By step（2）In the miscella that is obtained by extraction mutually be filtered, then subtracted
Pressure evaporation, which carries out recycling to extractant, can be obtained fresh peony flower medicinal extract；By step（2）In flower slag phase be evaporated under reduced pressure back
Receive extractant.
Preferably, the step（1）In tree peony be phoenix pellet tree peony, plucking time be morning 6:30~10：When 30
Between.
Preferably, the step（3）In, filter sizes employed in filter process are 3.0 ~ 7.0 μm.
Preferably, the step（3）In, the initial pressure of reduction vaporization is 4 ~ 5 MPa, the pressure of terminal is-
The MPa of 0.085MPa ~ -0.09, temperature is 30 ~ 45 DEG C, and is continued to after reaching authorized pressure 1 ~ 2 hour.
The beneficial effects of the invention are as follows：Using the fresh peony flower now plucked, colored or petal does not need the present invention as raw material entirely
Any pre-treatment, both reduced costs, and also simplified process flow；Fresh peony flower plucking time and condition require strictly, to go forward side by side
Row Refrigerated Transport, ensure that fresh peony flower is entirely colored or the freshness of petal and extract it is pure；Extracted at a lower temperature
It takes, active material in fresh peony flower and the exclusive fragrance of fresh peony flower, the tree peony extracted can be retained to the greatest extent
Fresh flower medicinal extract quality is good；Extractant is recycled and reused, and production cost and organic waste pollution are reduced；Relative to investment
Fresh flower amount for, for medicinal extract yield of the invention 0.1% ~ 0.3%, cost reduces by 10% or so.
