A new method was developed for effective separation and simultaneous determination of estrogens, gestagens, and androgens, including estrone, 17β-estradiol, testosterone, progesterone, and estriol, in infant formula. The samples were enzymatically digested with β-glucuronidase/arylsulfatase prior to microwave-assisted extraction. After the extract was cleaned up by gel permeation chromatography the...
A novel ultrahigh performance liquid chromatographic method is developed for analysis of 21 synthetic colorants with different acid–base property, solubility, and polarity. The meat samples were extracted by microwave-assisted extraction followed by cleanup with solid-phase extraction. The effective separation of the colorants in meat matrixes was achieved, and no interfering peaks could be detected...
