Abstract
The invention discloses a method for extracting coreopsis tinctoria pigment through an ultrasonic method. The method comprises the following specific steps: (1) manually selecting to remove sundries from coreopsis tinctoria picked during a full-bloom stage, drying the coreopsis tinctoria, crushing the dried coreopsis tinctoria through a crushing machine, screening the crushed coreopsis tinctoria, and weighing an appropriate amount of coreopsis tinctoria powder for standby application according to the volume of an extracting instrument; (2) performing ultrasonic assisted extraction on the products obtained in the step (1); (3) performing vacuum filtration on the products obtained in the step (2), mixing coarse filtrates and performing suction filtration so as to obtain extraction liquid, performing rotary evaporation on extraction liquid, concentrating so as to obtain pigment colloid, removing grease through diethyl ether, and drying the pigment colloid so as to obtain pigment powder. The method has the advantages that the technological processes are simple, the cost is low, and the original nutrient substances and the functional components in the coreopsis tinctoria are not damaged. The natural pigment extracted through the method is mild in performance and has no toxic or side effects.
Description
Technical field
The present invention relates to a kind of extracting method of natural pigment, belong to the separation and extraction technology field of biological products.
Background technology
The head inflorescence of the Kunlun snow chrysanthemum and the double-colored golden wave of composite family golden pheasant Chrysanthemum (Coreopsis tinctoria Nutt.), can be used as medicine after its drying, also can make tea-drinking, millet paste magneta colour.The Kunlun bright-colored quality of snow chrysanthemum ligule petal is plump, and tubulose petal color depth is applicable to extracting natural pigment.Comparatively synthetic colour has steady quality to natural pigment, dieing activity is good, have no side effect advantages such as even having medicine healthy sofa effect, and therefore, natural pigment wins increasing favor.Tradition restricted-access media pigment length consuming time, energy consumption is many, extraction yield is low, and ultrasonic-assisted extraction rule can alleviate problems.The present invention carries out from the extraction utilizing ultrasonic technique to the Kunlun snow asterin.
Summary of the invention
The object of this invention is to provide a kind of processing method utilizing the particular form of ultrasonic assistant tradition lixiviate to extract the Kunlun snow asterin, reach extraction efficiency high, the effect of energy-and time-economizing.
Concrete steps are:
(1) chrysanthemum is avenged through manually picking removing foreign material in the Kunlun that full-bloom stage is plucked, and it is dried under 60 ± 2 DEG C of conditions, after pulverizer is pulverized, crosses 60 mesh sieves.Take snow inulin end, 0.25g the Kunlun and insert 50mL Erlenmeyer flask, supersound extraction.
(2) be that the ethanol of 70-95% mixes according to the ratio of solid-liquid ratio 1: 25-35 (g: ml) by the product of step (1) gained and mass percent concentration, keep 60-80 DEG C of constant temperature to extract 45-75min, ultrasonic frequency is 40Hz.
(3) filtered by step (2) product vacuum, the coarse filtration liquid merging suction filtration after filtering is obtained sorrel suction filtration extracting solution, and obtain pigment colloid by concentrated after suction filtration extracting solution rotary evaporation, ether grease removal post-drying obtains pigment opaque.
Present invention process concise flow, with low cost, and do not destroy the Kunlun snow original nutritive substance of chrysanthemum and functional component.Utilize present method to extract the hot property of pigment temperature in the sky obtained, have no side effect.
Accompanying drawing explanation
Accompanying drawing is that traditional extraction changes comparing of generation in time with ultrasonic wave added restricted-access media effect.
Below in conjunction with example, the present invention is described in further detail.
A method for ultrasonic extraction the Kunlun snow asterin, its processing condition are:
(1) chrysanthemum is avenged through manually picking removing foreign material in the Kunlun that full-bloom stage is plucked, and it is dried under 60 ± 2 DEG C of conditions, crosses 60 mesh sieves after pulverizing.Take snow inulin end, 0.25g the Kunlun and insert 50mL Erlenmeyer flask, supersound extraction.
(2) the Kunlun is avenged inulin end to move in extraction equipment, add Extraction solvent ethanol according to the amount of solid-liquid ratio 1: 25-35, the concentration of ethanol is 70-95%.Keep Extracting temperature to be 60-80 DEG C in supersound extraction process, after selected temperature, constant temperature extracts 45-75min, takes out extracting solution suction filtration, obtains the Kunlun snow asterin extracting solution.
(3), after the Kunlun being avenged asterin extracting solution rotary evaporation, pigment colloid is obtained.Ether grease removal post-drying is utilized to obtain pigment opaque.
(4) chrysanthemum is avenged through manually picking removing foreign material in the Kunlun that full-bloom stage is plucked, and it is dried under 60 ± 2 DEG C of conditions, crosses 60 mesh sieves after pulverizing.Take snow inulin end, 0.25g the Kunlun and insert 50mL Erlenmeyer flask, supersound extraction.
(5) the Kunlun is avenged inulin end to move in extraction equipment, add Extraction solvent ethanol according to the amount of solid-liquid ratio 1: 25-35, the concentration of ethanol is 70-95%.Keep Extracting temperature to be 60-80 DEG C in supersound extraction process, after selected temperature, constant temperature extracts 45-75min, takes out extracting solution suction filtration, obtains the Kunlun snow asterin extracting solution.
(6), after the Kunlun being avenged asterin extracting solution rotary evaporation, pigment colloid is obtained.Ether grease removal post-drying is utilized to obtain pigment opaque.
Most preferred embodiment
