127-40-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 127-40-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,2 and 7 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 127-40:
(5*1)+(4*2)+(3*7)+(2*4)+(1*0)=42
42 % 10 = 2
So 127-40-2 is a valid CAS Registry Number.

Process for Synthesis of (3R,3'R,6'R)-Lutein and its Stereoisomers

-

Page/Page column 10-11; 24-25, (2009/10/30)

(3R,3′R,6′R)-Lutein and (3R,3′R)-zeaxanthin are two dietary carotenoids that are present in most fruits and vegetables commonly consumed in the US. These carotenoids accumulate in the human plasma, major organs, and ocular tissues. In the past decade, numerous epidemiological and experimental studies have shown that lutein and zeaxanthin play an important role in the prevention of age-related macular degeneration (AMD) that is the leading cause of blindness in the U.S. and Western World. The invention provides a process for the synthesis of (3R,3′R,6′R)-lutein and its stereoisomers from commercially available (rac)-α-ionone by a C15+C10+C15 coupling strategy. In addition, the present invention also provides access to the precursors of optically active carotenoids with 3-hydroxy-ε-end group that are otherwise difficult to synthesize. The process developed for the synthesis of lutein and its stereoisomers is straightforward and has potential for commercialization.

The present invention relates to nutritional supplements that provide an adult with essential vitamins and minerals that may be lacking in the adult's diet and prevent chronic diseases, such as osteoporosis. A number of combinations of nutrients in set ratios are provided to increase the body's ability to absorb and use the nutrients. These combinations are important in helping the body reach the proper balance required for maximized function. Because adults over the age of 50 years have different nutritional needs, nutritional supplements specifically designed for them are also provided.

METHOD OF RECOVERING XANTHOPHYLL

, (2008/06/13)

The present invention provides a method for collecting xanthophylls, the method comprising an adsorption step of contacting a sample containing xanthophylls with a hydrophilic resin to allow the resin to adsorb the xanthophylls; and a desorption step of eluting the xanthophylls adsorbed to the resin with a polar solvent. Preferably, the method comprises a step of washing the resin between the adsorption step and the desorption step. As the resin, a hydrophilic, acrylic and/or methacrylic resin is preferably used.

ISOLATION AND PURIFICATION OF CAROTENOIDS FROM MARIGOLD FLOWERS

Page/Page column 10-12, (2008/06/13)

The present invention explains a realistic and effective process for isolating and purifying carotenoids containing higher concentrations of carotenoids such as trans-lutein, trans-zeaxanthin, Cis-lutein, ?-carotene and Cryptoxanthin from Marigold flower petals under controlled conditions leaving no traces of any organic hazardous solvents. The process involves ensilaging marigold flowers, dehydration, solvent extraction, alkali hydrolysis of carotenoid esters with absolute alcohol, crystallization/purification using water, absolute alcohol mixture followed by filteration and drying until the crystals are considerably free from moisture and absolutely free from residual hazardous solvents. These crystals are suitable for nutraceutical and food products as supplements.
