Abstract

The invention discloses an extraction method for a rhodiola rosea essence substance. The extraction method comprises the following steps: (1) pre-treating rhodiola rosea and purifying water; (2) extracting the pre-treated rhodiola rosea and the pure water; (3) roughly filtering cooled rhodiola rosea soup and precisely separating; (4) filtering precisely-filtered liquid with a micro-pore membrane with the pore diameter of 0.25-0.45 micron; (5) concentrating refined purified liquid by using a reverse osmosis membrane at room temperature; (6) decompressing and concentrating the rhodiola rosea soup concentrated by the reverse osmosis membrane; (7) finally, obtaining an essence extractive. Compared with the prior art, the extraction method for the rhodiola rosea essence substance is used for extracting the essence of the rhodiola rosea, greatly improves the nutrition absorption rate, and has the advantages of high efficiency, environmental friendliness, safety, guarantees of the activity of effective components and the like; the taste and the nutritional components of the rhodiola rosea are kept and the rhodiola rosea essence substance is convenient to carry; the effects of the expensive rhodiola rosea can be developed completely.
