Abstract
The present invention is supercritical CO2 extraction process of obtaining wild rose extractive. The process includes freeze drying of wild rose at 0 deg.c to -30 deg.c, crushing and pulping, extracting in an extracting reactor with CO2 at flow rate of 40-80 kg/hr at 30-50 deg.c and 10-20 MPa for 3.5-5 hr, the first separation to collect coarse extractive, the second separation in a separating reactor, the second extracting at 30-50 deg.c and 10-16 MPa for 3.5-5 hr, and separation of the extractive in a column separator to obtain wild rose oil as the supernatant, wild rose water, and wild rose paste as the precipitate. CO2 as supercritical extractant has no toxicity, no side effect, no organic residue, no corrosion to extracting apparatus, great solubility and high extraction rate, and the present invention is suitable for industrial production.
Description
Technical field:
The present invention relates to the technology of wild rose extract, especially disclose a kind of method of supercritical carbon dioxide extraction wild rose extract, belong to the extracting method technical field of plant efficient part composition.
Background technology:
The extraction of effective constituents such as conventional Flos Rosae Rugosae quintessence oil or medicinal extract makes by squeezing or by organic solvent extractions such as alcohol, benzene, aldehyde under the normal temperature state, it is lower that effective constituent is removed rate, contain organic solvent residuals such as benzene, aldehyde toward contact, human body is produced detrimentally affect.
Summary of the invention:
The invention provides a kind of method of supercritical carbon dioxide extraction wild rose extract, have characteristics such as the rate of going out height, organic solvent-free be residual.
The isolating principle of the supercritical carbon dioxide extraction of wild rose extract is to utilize the dissolving power of supercritical co and the relation of its density, promptly utilize pressure and temperature to supercutical fluid solvent influence carry out.Under supercritical state, supercritical co liquid is contacted with wild rose to be separated, it is extracted the composition of polarity size, boiling point height and molecular weight size selectively successively.
Technical solution of the present invention may further comprise the steps: get the wild rose fresh flower and place-0～-30 ℃ of lyophilize, after the pulverizing making beating is sent in the extraction kettle, feed carbonic acid gas with 40～80kg/ hour flow velocity, keep 30～50 ℃ in temperature, pressure is to extract under 10～20Mpa condition 3.5～5 hours, carrying out the first time separates, collect the runic thing, crude extract continues to enter separating still and carries out secondary separation, pressure 10～16Mpa, 30～50 ℃ of temperature, extracted 3.5～5 hours, extract is put into pillar separating machine (change revolution 1～20,000) separate, getting the supernatant thing is wild rose oil, wild rose water, throw out is a wild rose sauce.
Positively effect of the present invention is: carbonic acid gas is as the supercritical extraction agent, and nontoxic, side effect and organic substance residues do not have corrosive nature to extraction equipment, and the solubleness of wild rose in CO 2 fluid is big, and the percentage extraction height is applicable to suitability for industrialized production.Adopting the rate that of technology wild rose oil of the present invention is 1～0.3 ‰, and rose water is 4～6 ‰.
Embodiment:
The following example is intended to further describe for example the present invention, rather than limit the present invention by any way, under the prerequisite that does not deviate from the spirit and principles in the present invention, any change or change that those of ordinary skills that the present invention did are realized easily all will fall within the claim scope that awaits the reply of the present invention.
Embodiment 1
Get wild rose fresh flower 10kg and place-20 ℃ of lyophilizes, after the pulverizing making beating is sent in the extraction kettle, feed carbonic acid gas with 40～80kg/ hour flow velocity, after 35 ℃ of temperature maintenances, pressure are to extract 3.5 hours under 10～20Mpa condition, send into separator and carry out the separation first time, collect the runic thing, crude extract continues to enter separating still and carries out secondary separation, 30～50 ℃ of pressure 16Mpa, temperature, extracted 4 hours, extract is put into pillar separating machine (revolution 20,000 changes) to be separated, getting the supernatant thing is wild rose water 60g, wild rose oil 3g, and throw out is wild rose sauce 9.5kg.
Embodiment 2
Get wild rose fresh flower 10kg and place-10 ℃ of lyophilizes, after the pulverizing making beating is sent in the extraction kettle, feed carbonic acid gas with 40～80kg/ hour flow velocity, after 50 ℃ of temperature maintenances, pressure are to extract 5 hours under the 12Mpa condition, send into separator and carry out the separation first time, collect the runic thing, crude extract continues to enter separating still and carries out secondary separation, 30 ℃ of pressure 16Mpa, temperature, extracted 3.5 hours, extract is put into pillar separating machine (change revolution 1～20,000) to be separated, getting the supernatant thing is wild rose water 40g, wild rose oil 10g, and throw out is wild rose sauce 9.5kg.
