Embodiment 1

[0029] Using the fruit of Jindenglong as raw material, zeaxanthin was prepared according to the following process:

[0030] Take 1000 grams of Jindeng fruit, freeze-dry, grind into powder, pass through a 100-mesh sieve, take the powder under the sieve, and add ethanol-cyclohexane solution containing 10% KOH in the ratio of Jindeng mass:solvent volume=1g:10ml (Ethanol: non-polar organic solvent volume ratio 1:1) 10 liters, stirred at 30°C for extraction and saponification for 2 hours; after the extraction, stand still for precipitation and separation; obtain the extract and filter residue;

[0031] Add 10 liters of the above ethanol-cyclohexane solution containing 10% KOH to the filter residue again for the second extraction and saponification; stir extraction and saponification at 30°C for 2 hours; stand for precipitation and separation after extraction; obtain the extract and filter residue;

[0032] Add 10 liters of the above ethanol-cyclohexane solution containing 10% KOH t...

Embodiment 2

[0036] Using Jindenglong persistent calyx as raw material, zeaxanthin was prepared according to the following process:

[0037] Take 1000 grams of persistent calyx, freeze-dry, grind into powder, pass through a 100-mesh sieve, take the powder under the sieve, add ethanol-cyclohexane solution containing mass concentration 10% KOH according to the ratio of persistent calyx mass:solvent volume=1g:50ml ( Ethanol: non-polar organic solvent (volume ratio 1:1) 50 liters, 30 ° C stirring extraction, saponification for 2 hours; after the extraction, stand still for precipitation and separation; obtain the extract and filter residue;

[0038]Add 50 liters of the above ethanol-cyclohexane solution containing 10% KOH to the filter residue again for the second extraction and saponification; stir extraction and saponification at 30°C for 2 hours; after the extraction, let it stand for precipitation and separation; obtain the extract and filter residue;

[0039] Add 10 liters of the above et...

Abstract

The invention relates to a method for extracting zeaxanthine and particularly relates to the method for extracting zeaxanthine from physalis alkekengi and fruits through a one-pot method. Both the extracting solution and saponification solution are simultaneously added into the physalis alkekengi and fruits, extraction and saponification are carried out in one step, and the zeaxanthine extractive can be obtained through simply separating and drying. According to the method, extraction and saponification are completed in one step; the method is simple, has high efficiency, uses a little amount of organic solvent, obtains high yield of zeaxanthine, can be used in fields such as food, health food, medicine, cosmetic and the like, and has good industrial application prospect.

Description

technical field [0001] The invention relates to a method for extracting zeaxanthin, specifically a one-pot method for extracting zeaxanthin from calyx calyx and fruit. The method for preparing zeaxanthin of the invention has the advantages of simple process, high efficiency, and low solvent consumption. Less, high zeaxanthin yield characteristics. The natural zeaxanthin extracted from the calyx and its fruit can be used in food, health food, medicine, cosmetics and other fields. Background technique [0002] Zeaxanthin (3,3'-dihydroxy-β-carotene, C40H56O2), also known as zeaxanthin, is a carotenoid xanthin with a hydroxyl group. [0003] [0004] Molecular structure of formula 1 zeaxanthin and lutein [0005] Zeaxanthin has two chiral carbons at 3 and 3', corresponding to four isomers, namely (3R,3'S)-, (3S,3'R)-, (3R,3'R) -,(3S,3'S)-Zeaxanthin. Due to the symmetry of the molecular structure of zeaxanthin, (3R,3’S)-, (3S,3’R)-zeaxanthin have exactly the same structure...
