Animal and vegetable fats and tocopherols
Tocotrienol content by HPLC
1 Scope
This standard specifies the determination by high performance liquid chromatography (HPLC) Animal and vegetable fats free α-, β-, γ-, δ- tocopherol and tocotrienol-containing
Method quantity.
For products containing tocopherol and tocotrienol esters, it is necessary to saponification treatment.
Note. A suitable method is described including cryogenic saponification methods in Appendix B.
2 Normative references
The following documents contain provisions which, through reference in this standard and become the standard terms. For dated references, subsequent
Amendments (not including errata content) or revisions do not apply to this standard, however, encourage the parties to the agreement are based on research

3 Terms and Definitions
The following terms and definitions apply to this standard.
3.1
Tocopherol content tocolcontent
This standard specifies the method for the determination of the mass fraction of each monomer tocopherol sum.
Note. the content expressed in milligrams per kilogram.
Principle 4
The test sample was dissolved in n-heptane, the respective monomers by high performance liquid chromatography separation tocopherol. With a standard solution Determination of correction
Coefficient calculation content of each tocopherol.
5 Reagents
The reagents were HPLC grade or equivalent rank with.
5.1 α-, β-, γ- and δ- tocopherol and tocotrienol standard material.
Without tocopherol standard material which can be a mixture of soybean germ oil and wheat as a standard substance, subject to the standard substance α- tocopherol
Referring to determine the content of which α-, β-, γ- and δ- tocopherol.
Without tocotrienol standard substance, palm oil can be used as a standard substance, subject to α- tocopherol as a standard reference material, which is determined
α- and γ- tocotrienol content.
Note. α-, β-, γ- and δ- tocopherol and tocotrienol standard substance can choose Merk1
) The company's products. α- tocopherol standard substance more products, purity
Between 85% to 100%, making it necessary concentration of the standard UV spectrophotometer dispensed (see 9.1.1).
Capacity of 50mg standard product contains α-, β-, γ- and δ- tocopherol of 95% purity (each can be reached) for HPLC use. Merk
Produced by tocotrienol standard (set613432) can also be purchased from Calbiochem company. Each bottle capacity of 50mg of standards
Contains α-, β-, γ- and δ- tocotrienol purity up to 95% (γ- tocotrienol 75%), for the use of HPLC.
This information is provided for the convenience of users of this standard, this standard is not as endorsement of the product.
