Abstract
The microwave radiation extracting process of lutein adopts lutein containing plant material or bacteria, such as orange peel, or photosynthetic bacteria as material and various organic solvent as extractant. The present invention features the cell wall breaking extraction process under microwave radiation with microwave radiation period of 10-60 sec and power of 100-800 W. The obtained extracted liquid is produced into lutein through further saponification and chromatographic separation.
Description
Technical field the present invention relates to a kind of microwave extract method of xenthophylls, belongs to the technology of being extracted xenthophylls by plant that contains xenthophylls or bacterium.
Background technology xenthophylls has another name called " plant lutein ", is a kind of natural pigment that extensively is present in vegetables, flowers, fruit and some algae bio.As far back as the mid-80 in last century, the western medicine researchist just finds that the contained natural carotenol of plant is a kind of antioxidant of excellent performance.A certain amount of xenthophylls is joined in the food, can prevent a series of diseases that human body causes because of organ senescence.Foreign study confirms, the visual deterioration that xenthophylls can prevent senile eyeball macula retinae to degenerate to cause is with blind.The other function of xenthophylls comprises prevention cell aging and biological organs aging.
Summary of the invention the purpose of this invention is to provide a kind of new xenthophylls extracting method, and its equipment is simple, extracts thoroughly and time-saving energy-saving.The present invention utilizes microwave extraction xenthophylls.Under microwave irradiation effect, strong polar molecule solvent will produce instantaneous polarization and with 2.45 * 10
9The speed of inferior/second is done the reversal of pole campaign, this just may produce certain microcosmic " disturbance " influence to liquid film layer, make the thinning of liquid film that is attached to around the solid phase make bonding force between solvent and the solute be subjected to a certain degree weakening, thereby the suffered resistance of the diffusion process that makes solid-liquid leaching reduces, and promotes the carrying out of diffusion process.Simultaneously molecule has so frequent swing, and its friction produces a large amount of heat energy and impels cell rupture, makes enchylema overflow and is diffused in the solvent.Compare with usual manner heating, speed of response soon, shorten the reaction times greatly has energy-efficient advantage.Equipment is simple, and Working environment cleaning, a small amount of extraction use household microwave oven to finish.It is characterized in that described xenthophylls is extracted and got by plant that contains xenthophylls or bacterium, uses the solvent heating and refluxing extraction with tangerine peel under the microwave radiation condition.The extracting solution that reaction generates is through saponification, and column chromatography gets xenthophylls.Described solvent can be ethanol, acetone, ether, chloroform equal solvent.
During described extraction, microwave power can be 100 watts～800 watts.Reaction times can be 10 seconds～and 1 minute.The add-on of described solvent can be 1～10 times that waits to put forward amount.
Embodiment embodiment 1 pulverizes tangerine peel, add acetone and in microwave oven, carry out carry out microwave radiation heating, while hot extracting solution is poured in the separating funnel after taking out beaker, mixing shakes up, continue 4～5 minutes, be placed on the iron stand then and leave standstill, pour out most of upper strata liquid after the layering, through saponification, column chromatography gets xenthophylls.
Claims (4)
1. the microwave extract method of an xenthophylls is characterized in that described xenthophylls is got by the plant extract that contains xenthophylls, uses the solvent heating and refluxing extraction with raw material under the microwave radiation condition.The extracting solution that reaction generates is through saponification, and column chromatography gets xenthophylls.Described solvent can be ethanol, acetone.
2. by the extracting method of the described xenthophylls of claim 1, it is characterized in that adopting microwave radiation broken wall extracting method.
