Problems solved by technology

[0004] It should be said that regular consumption of carotenoid-rich red duck eggs and other such foods will have certain health care and anti-cancer effects on the human body, but conventional consumption is affected by factors such as low and uncertain doses, differences in human digestion and absorption, etc. , not enough to achieve significant anti-cancer pharmacological effects

Embodiment 1

[0023] Take the raw material red duck egg, the Roche chroma of the yolk of the red duck egg reaches 19 degrees, after routine cleaning and disinfection, the egg yolk is separated from the egg white, and freeze-dried to obtain freeze-dried egg yolk powder for later use. Take 100 grams of freeze-dried egg yolk powder and use petroleum ether: acetone (2:1V / V) mixed solvent extraction 3 times, each time with 400 ml of mixed solvent to extract for 60 minutes, separate the extract, add 20 ml of distilled water, let stand, make petroleum ether and acetone layered, release the acetone layer, distilled water Wash 2 to 3 times, 15 ml each time, release the water layer, add 3 g of anhydrous sodium sulfate to the petroleum ether layer, recover the petroleum ether layer, obtain the extract containing carotenoids, and concentrate the extract in vacuum at 40°C , put the concentrated extract on a silica gel column, first use petroleum ether: acetone mixture (24:1V / V) to elute non-carotenoids, ...

Embodiment 2

[0025] Take the raw material red duck egg, the Roche chroma of the yolk of the red duck egg reaches 15 degrees, after routine cleaning and disinfection, the egg yolk is separated from the egg white, and freeze-dried to obtain freeze-dried egg yolk powder for later use. Take 100 grams of freeze-dried egg yolk powder and use petroleum ether: acetone (1:1V / V) mixed solvent extraction 3 times, each time with 300 ml of extract, extract for 50 minutes, separate the extract, add 15 ml of distilled water, let stand, make petroleum ether and acetone layered, release the acetone layer, Wash with distilled water 2 to 3 times, 20 ml each time, release the water layer, add 4 grams of anhydrous sodium sulfate to the petroleum ether layer, recover the petroleum ether layer, and obtain the extract containing carotenoids, and vacuum the extract at 40 ° C. Concentrate, put the concentrated extract on a silica gel column, first use petroleum ether: acetone mixture (24:1V / V) to elute non-carotenoi...

Abstract

An anticancer carotenoid for preventing and treating liver cancer is prepared from the yolk of red-core duck egg through extracting with the mixed solvent of petroleum ether and acetone, separation, vacuum concentrating, purifying, and low-temp drying. Its advantages are high extracting rate and recovered solvent.

Description

technical field [0001] The invention relates to a carotenoid with anticancer effect extracted from carotenoid-rich red duck eggs and a preparation method thereof. Background technique [0002] Modern studies on the biological activity of carotene compounds, especially the antitumor activity, are very attractive. Because certain carotenoid compounds can be converted into vitamin A in the human body, this type of carotenoid is called provitamin A. Studies have shown that people who are deficient in vitamin A and carotenoids are prone to various cancers. In addition, carotenoids also have a significant effect on the prevention and treatment of cardiovascular diseases. [0003] Among the laying ducks stocked or raised in the lake area, when the laying duck eats a certain amount of weed grass or feed containing weed grass, the yolk of the laid eggs is red, which is called red duck egg. Experiments have proved that the main component that forms the red substance in the yolk in ...
