Determination of Tocotrienols and Tocophenrols Using HPLC-ECD

Figure 1. Structures of the various tocopherol and tocotrienol vitamers. Introduction There are eight vitamers of vitamin E (alpha-, beta-, gamma-, and delta-tocopherols and the corresponding tocotrienols) (Figure 1), differing in their biological activity and distribution in foods. Most often vitamin E’s role is usually associated with its antioxidant activity. For example, α-tocopherol is a w...

Simultaneous Determination of Sulfamethoxazole and Phthalazine by HPLC and Multivariate Calibration Methods

Two multivariate calibration methods are compared for the simultaneous chromatographic determination and separation of Sulfamethoxazole (SMX) and Phthalazine (PHZ) by High Performance Liquid Chromatography (HPLC). Multivariate calibration techniques such as Classical Least Squares (CLS) and Inverse Least Squares (ILS) were introduced into HPLC to determine the quantification by using UV d...

Determination of urinary free cortisol by HPLC.

We here report a reversed-phase HPLC method for the determination of free cortisol in human urine, using methylprednisolone as the internal standard. Before chromatography, samples were extracted with a C18 solid-phase extraction column and the steroids were separated on a LiChrospher 100 C18 column with a mobile phase of methanol/acetonitrile/water (43/3/54 by vol). Linearity, precision, and a...
