Vitamin E represents a group of lipophilic phenolic compounds, including α‐tocopherol, β‐
tocopherol, γ‐tocopherol, and δ‐tocopherol, and α‐tocotrienol, β‐tocotrienol, γ‐tocotrienol …

Reversed-phase liquid chromatographic (RPLC) separation of isomers and homologues of
similar polarity is challenging. Tocopherol isomers and homologues are one such example …

Tocopherol homologues are important fat‐soluble bioactive compounds with high nutritional
value. However, it is of great challenge to separate these homologues because of their high …

This work reports the first use of a monolith with method development for the separation of
tocopherol (TOH) compounds by CEC with UV detection. A pentaerythritol diacrylate …

Of the eight natural vitamin E congeners (α-, β-, γ-, and δ-tocopherol and α-, β-, γ-, and δ-
tocotrienol), the non-α-tocopherol congeners have unique biological properties that may …

Vitamin E is recognized as an essential vitamin since its discovery in 1922. Most vegetable
oils contain a mixture of tocopherols and tocotrienols in the vitamin E composition …

In this study capillary electrochromatography (CEC) was used for the separation of three
tocopherols (TOHs), namely δ-, γ-and α-TOH and the antioxidant compound, butylated …

This work reports the first use of a monolith with method development for the separation of
tocopherol (TOH) compounds by CEC with UV detection. A pentaerythritol diacrylate …

The comparison of tocopherol isomer separation achieved using different stationary-phase
alkyl chain lengths (ie, C18 vs C30) and modes of alkyl phase attachment to the silica-based …

Four stationary phases containing different groups such as: C18, C30, alkylamide, and
cholesterolic, were presented for simultaneous HPLC analysis of structural isomers of …
