Abstract
The invention relates to a new process for extracting high-content lutein ester from a tagetes erecta l extract. The new process comprises: placing a tagetes erecta l extract into a closed container, carrying out closed extraction with an organic solvent, precipitating, filtering, rinsing the filter cake by using an alcohol, and drying the rinsed precipitate under a negative pressure condition to obtain the lutein ester with the content of not less than 80%, wherein the total yield is not less than 70%. According to the present invention, with the new process, the high-content lutein ester can be effectively extracted from the tagetes erecta l extracts having different qualities, and the problem that the tagetes erecta l extracts having different qualities require different extraction processes is solved; and the process has the simple operations and is suitable for industrial mass production.
Description
Technical field:
The present invention relates to extracting the new technology of high-content lutein ester from marigold extractum
Background technology:
Phylloxanthin is the key component of human eye retina's macular area, and human body itself can not synthesize, and relies primarily on picked-up from food.State for many years
Inside and outside research shows, high-content lutein ester is more beneficial for absorption of human body.So the lutein ester extracting high-load from marigold extractum in recent years becomes
Study hotspot.Because marigold extractum quality is different, to extract high-content lutein ester, technique used also differs, and is so that high-volume is raw
Produce high-content lutein ester and bring very big restriction, greatly reduce the yield of product.
Content of the invention:
The problem to be solved in the present invention is to disclose a kind of new technology extracting high-content lutein ester from marigold extractum.
Concrete solution is as follows:
Marigold extractum is placed in airtight container and carries out airtight extraction with organic solvent normal butane, condition is: pressure 0～1mpa, time 0.1～2
Hour, temperature stirs at -35 DEG C～50 DEG C, is rinsed filter cake dehydrated alcohol, then will rush after filtering through precipitation under conditions of 0 DEG C～60 DEG C
Precipitate after washing is dried under conditions of negative pressure.
The positive effect of the present invention:
1. solve the problems, such as that the raw material (marigold extractum) of different quality needs different techniques to extract high-content lutein ester.
2. lutein ester content height (more than 80%) extracted under this technique, high income (more than 70%)
3. process is simple, is easy to high-volume commercial production.
Specific embodiment:
Marigold extractum is placed in airtight container and carries out airtight extraction with organic solvent normal butane, condition is: 0～1mpa, 0.1～2 hour time,
Temperature stirs at -35 DEG C～50 DEG C, after filtering through precipitation is rinsed filter cake dehydrated alcohol under conditions of 0 DEG C～60 DEG C, after then rinsing
Precipitate is dried under conditions of negative pressure.Obtain the lutein ester that content is not less than 80%, total recovery is not less than 70%.
Claims (4)
1. extract the new technology of high-content lutein ester from marigold extractum it is characterised in that marigold extractum is placed in airtight container with organic molten
Agent extracts, and precipitates the solvent washing with micro- poison for the filter cake after filtering, the precipitate after rinsing is dried under negative pressure, and final acquisition content is not low
In 80% lutein ester.
2. the technique extracting high-content lutein ester from marigold extractum according to claims 1 is it is characterised in that extract high-content lutein
Ester normal butane is solvent, and extracting pressure is 0～1mpa, and extraction time is: 0.1～2 hour, temperature was between -35 DEG C～50 DEG C.
3. according to claims 1 from marigold extractum extract high-load leaf Huang rope ester technique it is characterised in that precipitation filter after filter cake
It is rinsed with micro- poison dehydrated alcohol, rinse temperature between 0 DEG C～60 DEG C.
4. according to claims 1～3 from marigold extractum extract high-content lutein ester technique it is characterised in that precipitate is in negative pressure
Under the conditions of be dried.
