Development of a fluorescent probe for detecting Al in cooked wheaten food based on phosphonic acid group functionalized polythiophene derivatives.

As an unnecessary trace element, the content of aluminium in biological systems should be strictly controlled. Therefore, it was necessary to develop a convenient method for detection of aluminium ions. In this study, a fluorescent probe based on polythiophene derivatives was developed and used to detect Al in Chinese traditional pasta.

[Study on chemical constituents of Kochia scoparia].

Objective: To investigate the chemical constituents of Kochia scoparia.

Methods: The constituents of EtOAc-soluble portion were isolated and purified by silica gel column chromatography. Their structures were identified by spectral features.
