It is particularly beneficial for individuals who may not consume enough vitamin E through their diet.
Used in Preventive Healthcare:
In the healthcare industry, 3,4-dihydro-2,7,8-trimethyl-2-(4,8,12-trimethyltridecyl)-2H-benzopyran-6-ol is used as a preventive measure against certain illnesses. Its antioxidant properties are believed to help reduce the risk of developing conditions such as cancer and heart disease by neutralizing harmful free radicals.
Used in Cosmetics and Skincare Products:
3,4-dihydro-2,7,8-trimethyl-2-(4,8,12-trimethyltridecyl)-2H-benzopyran-6-ol is used as an ingredient in cosmetics and skincare products for its antioxidant and moisturizing properties. It helps to protect the skin from environmental damage and supports the maintenance of a healthy skin barrier.
Used in Food Fortification:
In the food industry, 3,4-dihydro-2,7,8-trimethyl-2-(4,8,12-trimethyltridecyl)-2H-benzopyran-6-ol is used for fortifying products with vitamin E, ensuring that consumers receive the recommended daily intake of this essential nutrient. This is particularly important for products that are low in natural vitamin E content or for those targeting populations with specific nutritional needs.

Novel Tocopherol Compounds VII. γ-Tocopherol-5-carboxylic Acid - A Novel Route to γ-Tocopherol

A novel route for the synthesis of γ-tocopherol starting from the readily available vitamin E (α-tocopherol) has been found. The key step is the photochemical decarboxylation of γ-tocopherol-5- carboxylic acid.

FORMATION OF CHIRAL 4-CHROMANONES USING CHIRAL PYRROLIDINES IN THE PRESENCE OF ACIDS

The present invention relates to a synthesis of chromanones or chromanes in a stereospecific matter in view of the 2-position in the chromanone or chromane ring. It has been found that this synthesis is particularly possible in the presence of a chiral compound of a specific type and of at least one Bransted acid or in the presence a specific chiral compound having a Bransted acid functional group in the molecule.

PROCESS OF SEPARATING CHIRAL ISOMERS OF CHROMAN COMPOUNDS AND THEIR DERIVATIVES AND PRECURSORS

The present invention relates to a process of separating chiral isomers of chroman compounds, particularly tocopherols and tocotrienols as well as the esters and intermediates thereof. It has been found that this process allows a separation of the desired isomer with a higher yield and enables the use of the non-desired isomers in a very efficient way. Said process is particularly useful when implemented in an industrial process. Furthermore, it has been found that this process allows using isomer mixtures as they result from traditional industrial synthesis.

Process for separating tocopherol homologues

Methods for separating gamma and delta homologues of tocopherol are described.

3-methoxybenzyl thiourea derivatives and improved lipid compositions containing same

Also provided are methods for enhancing the oxidative stability of a lipid comprising supplementing a base lipid in need of enhanced oxidative stability with at least one 1-(3-methoxybenzyl)-3-substituted thiourea compound of the present invention.

Preparation of chromanyl derivatives

A process for the preparation of chromanyl derivatives of the formula I STR1 where R1 is hydrogen, C1 -C8 -alkyl, aryl, aralkyl, Si(R4)3, C(=O)R4 or C1 -C4 -alkoxymethyl, R2 and R3 are hydrogen or C1 -C3 -alkyl, and R4 is C1 -C8 -alkyl or aryl, which comprises decarboxylating 5-carboxychromanyl derivatives of the formula II STR2 where the substituents R1 to R3 are as defined above and 5-carboxylchromanyl derivatives of the formula II.

Biotenside esters and phosphatides with vitamin-D and vitamin-E compounds

New biotenside esters and phosphatides formed with Vitamin-D and Vitamin-E compounds possessing a pronounced antitumor activity, processes for their production as well as for the preparation of concentrates and pharmaceutical compositions containing these new esters and phosphatides, and their use for treating tumors are described.

Process for separation of tocopherol homologues

A process for separating the various members of a tocopherol homologue mixture to obtain fractions of the separate tocopherol homologues. The isolation of the various tocopherol homologues is accomplished by selective deacylation of tocopheryl esters followed by separation of the esters from the free tocopherols.
