Abstract
The invention relates to the technical field of extracting essential oil from flowers, in particular to a peony flower essential oil extracting method. The method comprises the following steps that dried peony flowers are purified, dried and smashed to reach the specification of 10 meshes for use; the peony flowers are placed into a supercritical carbon dioxide extraction device, supercritical carbon dioxide extraction is performed on the condition of 40 MPa and 55 DEG C, and the extraction time is controlled within 100 min; alcohol with the volume percentage being 85% and the weight two times that of the extraction solution is added, standing is performed for 12 h under the temperature of 22 DEG C, and a mixed alcohol solution is obtained; the mixed alcohol solution is fed into a molecular distillation tank to be subjected to vacuum distillation, purification and condensation, and the finished peony flower essential oil is obtained; the pressure inside the distillation tank is controlled to be 0.06 MPa, the compressed air pressure is not larger than 0.5 MPa, and the vacuum degree inside the tank is 45 MPa. Compared with the prior art, the method has the advantages that the method is easy to implement, the obtained peony flower essential oil is good in quality, and the oil extraction rate can reach 0.03%.
Description
Technical field
The present invention relates to from the technical field spending middle extraction quintessence oil, particularly to a kind of peony essential oil extracting method.
Background technology
Peony essential oil is to spend middle extraction plant essence, the aminoacid needed rich in multiple human body and trace element from Paeonia suffruticosa.Peony essential oil contains abundant Paeonia suffruticosa polyphenol, is superpower antioxidant, is of value to delay skin aging, it is suppressed that mottle, senile plaque, prevents and treats acne, bright and clean skin quality.Peony essential oil be mainly composed of alcohols, alkanes, esters, ketone and fragrance hydrocarbons and their derivates, also contain a small amount of aldehydes, pyrans, alkene class and phenols etc..It effectively can suppress skin pigment formation, smoothing wrinkle, minimizing skin splash and women striae gravidarum by scavenging activated oxygen.Improve blood microcirculation, remove skin toxins, improve dry skin and pore refining, make skin smooth, flexible.Peony essential oil is natural plant hormone, hormone secretion in balance women body, alleviates menalgia, nourishes uterus.Its fragrant composition is mainly phenethanol and linalool oxide.Aldehyde in quintessence oil, ester, ketone are that it has the reason of notable antioxidant activity.
The extraction efficiency of existing peony essential oil is low, therefore is necessary to provide a kind of extracting method that can improve oil yield and ensure quintessence oil quality.
Summary of the invention
Present invention aims to the defect of prior art and deficiency, it is provided that a kind of peony essential oil extracting method.
For achieving the above object, the technical solution used in the present invention is:
A kind of peony essential oil extracting method of the present invention, comprises the steps:
A, by dry Flos Moutan remove impurity, dry, be crushed to 10 orders, standby；
B, being placed in supercritical carbon dioxide extraction apparatus by Flos Moutan, at 40MPa, carry out supercritical carbon dioxide extraction under 55 DEG C of conditions, extraction time controls at 100min；
C, addition weight are the 85%(volume of extract weight 2 times) ethanol, at 22 DEG C, stand 12h, filter, obtain mixed alcohol liquid；
D, by mixed alcohol liquid send into molecular distillation tank carry out vacuum distilling purification condensation, prepare finished product peony essential oil；Distillation pressure inside the tank controls at 0.06MPa, and compressed air pressure is less than 0.5MPa；Vacuum in tank: 45MPa.
The present invention compared with prior art provides the benefit that: this method is simple to operate, and the peony essential oil quality of preparation is good, and oil yield is up to 0.03%.
Detailed description of the invention
Describing the present invention below in conjunction with specific embodiment, following embodiment and explanation are only used for explaining the present invention, but not as a limitation of the invention.
A kind of peony essential oil extracting method of the present invention, comprises the steps:
A, by dry Flos Moutan remove impurity, dry, be crushed to 10 orders, standby；
B, being placed in supercritical carbon dioxide extraction apparatus by Flos Moutan, at 40MPa, carry out supercritical carbon dioxide extraction under 55 DEG C of conditions, extraction time controls at 100min；
C, addition weight are the 85%(volume of extract weight 2 times) ethanol, at 22 DEG C, stand 12h, filter, obtain mixed alcohol liquid；
D, by mixed alcohol liquid send into molecular distillation tank carry out vacuum distilling purification condensation, prepare finished product peony essential oil；Distillation pressure inside the tank controls at 0.06MPa, and compressed air pressure is less than 0.5MPa；Vacuum in tank: 45MPa.
The present invention compared with prior art provides the benefit that: this method is simple to operate, and the peony essential oil quality of preparation is good, and oil yield is up to 0.03%.
The above is only in order to conveniently to illustrate the present invention, and in the scope created without departing from the present invention, that is familiar with that those skilled in the art of this technology does various simple covert should belong to protection scope of the present invention with modifying.
