Background: The efficiency of herbal medicinal products depends on the quantity of active ingredients in them, which can vary considerably in different contents. Hence, the quality control of herbal medicines is a critical concern.
Objective: This paper aims to provide a succinct review of recent chemometrics applications in solving the uncertainty of the authentication of herbal medicines over the last two decades.
Bee pollen collected by honeybees () is one of the bee products, and it is as valuable as honey, propolis, royal jelly, or beebread. Its quality varies according to its geographic location or plant sources. This study aimed to apply rapid, simple, and accurate analytical methods such as attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR) and high-performance liquid chromatography (HPLC) along with chemometrics analysis to construct a model aimed at discriminating between different pollen samples.
