Description
Technical field
The invention belongs to the technical field that natural product active ingredient extracts, be specifically related to a kind of method of high yield and purity extraction jasminoidin from cape jasmine fruit.
Background technology
Jasminoidin is a kind of effective constituent in cape jasmine fruit, has the effects such as anti-oxidant, anti-inflammatory, extensive application in medicine, health care, biological detection etc.Jasminoidin is iridoid glycoside compounds, different name Geniposide.Mainly natural edible coloring agent gardenia blue and gardenia red can be made in foodstuffs industry.In the 56 kinds of pigments listed in China GB2760-2007 " foodstuff additive use hygienic standard ", cyanine only has gardenia blue pigment and phycocyanin (i.e. Phycocyanins, C-pigment) two kinds.At present, at home and abroad all supply falls short of demand on market for natural blue pigment, and therefore active development high efficiency extraction jasminoidin technology, will have great realistic meaning and considerable market outlook.The China that is extracted in about jasminoidin has patent report, but the method for these patents uses Flavonoids by Macroporous Adsorption Resin to prepare jasminoidin mostly.As patent CN1939458A adopts macroporous absorption to prepare Fructus Gardeniae extract, because the remaining inert solvent of macroporous adsorbent resin endoporus is high, pre-treatment difficulty is large, and desorb is insufficient, affects separating effect, and resin regeneration difficulty, production cost increases.And the same model resin that same manufacturing enterprise produces, between each batch, greatly, poor reproducibility in separation and purification, is unfavorable for continuous prodution for specific surface area and functional group content difference.Double-aqueous phase system (ATPE) has easy to operate with it, separation efficiency is high, to many characteristics such as separate substance zero destructions, is widely used in product separation and the extraction in the fields such as biological chemistry, cytobiology and biochemical industry.Although existing bibliographical information utilizes ethanol/dipotassium hydrogen phosphate double-aqueous phase system to carry out the research of jasminoidin extraction, the jasminoidin purity obtained only has 62.12%, and yield is 96.32%.The factor affecting double-aqueous phase system extraction efficiency mainly contains solvent species, the kind of salt and the mass ratio of solvent and salt.Even if same double-aqueous phase system extraction different substances time, because the structures and characteristics of extract is on the impact of dissolution with solvents ability, the solvent in its system and the mass ratio of salt also variant.Virahol has the advantages such as inexpensive, low toxicity, viscosity are less, utilizes Virahol to make extraction agent and inorganic salt at present and forms double-aqueous phase system separation and purification jasminoidin there is not been reported.For this reason, we by Virahol with the stability of the double-aqueous phase system of sylvite, sodium salt and ammonium salt and study the alkoxide ratio in system and pH value, set up the Virahol/salt double water-phase new system of separation and purification jasminoidin.The method is easy and simple to handle, green high-efficient, and economy saves time, be easy to amplification.It has not only widened the double-aqueous phase system kind of extraction jasminoidin, improve the efficiency of jasminoidin separation and purification, and this technique also can be applicable to extraction and the production of other pigments.
